MAVROS

MAVLink extendable communication node for ROS 2.

It provides communication with the autopilot via serial port, UDP or TCP (e.g. PX4 or ArduPilot), an internal proxy for a Ground Control Station, a plugin system for ROS-MAVLink translation, OFFBOARD mode support, and geographic coordinate conversions.

Only for Linux.

The ROS API (topics, services, parameters) of every plugin is documented in the plugin reference and the full documentation.

The transport library is split into the standalone libmavconn package, which is usable outside ROS.

Quick start

sudo apt install ros-${ROS_DISTRO}-mavros
sudo ros2 run mavros install_geographiclib_datasets.sh
ros2 launch mavros px4.launch

CHANGELOG

Changelog for package mavros

2.17.0 (2026-11-11)

  • Merge pull request #2358 from agyoungs/sys-time-match-timesync-replies sys_time: use only the FCU's replies to our own TIMESYNC requests

  • plugin: move AddressedToUsAndOk back to the mission base This reverts commit 1474e415. sys_time was the only other user and now checks the target ids in its handler. The filter knows only the common dialect, so it should not be offered as a generic one. Co-Authored-By: Claude Fable 5.2 <<noreply@anthropic.com>>

  • sys_time: check TIMESYNC target ids in the handler PX4 v1.14 - v1.17 has the target fields in TIMESYNC, but leaves them uninitialised in its replies, so a filter on them may drop the replies to our own requests. Go back to SystemAndOk and check in the handler:

    • a request is answered only if it is addressed to us or broadcast;

    - a reply is matched by ts1 only, its target fields are not checked. Co-Authored-By: Claude Fable 5.2 <<noreply@anthropic.com>>

  • Merge pull request #2366 from mavlink/ftp-burst-followup ftp: follow-up fixes for burst sequence window (#2361)

  • ftp: do not skip a sequence window after an unsupported burst A kErrUnknownCommand NAK is the only reply to a burst request, so there is no stream to separate from. Clear the reservation before falling back to kCmdReadFile, FCUs without burst support keep plain +1 sequencing. Tests, follow-up to #2361:

    - the fallback test asserts the sent sequence numbers and no replays, it passed without the plugin change before;

    - the late EOF test no longer uses the reply cache, so it does not duplicate close_after_final_burst_is_not_replayed_as_eof;

    - the wraparound test puts the burst stream on the 16-bit boundary: last data packet at 65535, cached EOF NAK at 0, close past the window. Co-Authored-By: Claude Fable 5.2 <<noreply@anthropic.com>>

  • Merge pull request #2361 from AscendEngineering/fix/ftp-burst-failed-close ftp: Standard FTP read after burst FTP read sequence error

  • Fixed Standard FTP read after burst FTP read

  • test: sys_time: check ignored TIMESYNC messages with a valid one after The tests that a request or reply is ignored waited a fixed time and then checked nothing came out, so on a slow machine they could pass without the plugin having acted. The plugin handles an injected message before inject() returns and its replies and statuses arrive in order, so each such check now sends a valid message after the ignored one and checks that the valid one's result is the only one. The fixed sleep in inject() goes, and the positive checks compare the remote timestamp rather than a count. Each check fails when the behaviour it guards is removed: any reply component accepted, ts1 not checked, SystemAndOk instead of AddressedToUsAndOk, or a pending request not removed once used. Co-Authored-By: Claude Opus 5.5 <<noreply@anthropic.com>>

  • sys_time: address review: clock steps, component 0, test helpers

    - Record each request's ts1 as sent. Forcing ts1 to increase kept it above an old maximum after our clock stepped back (sim time with a SITL restart, an NTP step), so every RTT underflowed and was rejected until the clock caught up. Duplicate ts1 values are harmless, as each reply takes one pending entry.

    - Treat target component 0 as any component. Warn (throttled) when a reply to one of our requests comes from another component, the case a misconfigured target component produces.

    - Test helpers: convert_message() zero-initialises the message and sets msgid and len, so the target-field checks no longer read garbage, and capture_sink() returns a CaptureBuffer read through a locked snapshot().

    - Note in AddressedToUsAndOk that it only knows common-dialect messages. New tests: target component 0, and sync after the clock steps back; both fail on the previous commit. Co-Authored-By: Claude Opus 5.5 <<noreply@anthropic.com>>

  • sys_time: use only the FCU's replies to our own TIMESYNC requests Any TIMESYNC with tc1 > 0 from the target system counted as a reply to our request, whatever its component and ts1. When other components also timesync with the FCU (a GCS, companion apps), the FCU's replies to them reach us too, each a sample against another clock: high-deviation rejections and "Time jump detected" resets. A reply now counts only if it comes from the target component and echoes the ts1 of one of our pending requests, each used once.

MAVROS

MAVLink extendable communication node for ROS 2.

It provides communication with the autopilot via serial port, UDP or TCP (e.g. PX4 or ArduPilot), an internal proxy for a Ground Control Station, a plugin system for ROS-MAVLink translation, OFFBOARD mode support, and geographic coordinate conversions.

Only for Linux.

The ROS API (topics, services, parameters) of every plugin is documented in the plugin reference and the full documentation.

The transport library is split into the standalone libmavconn package, which is usable outside ROS.

Quick start

sudo apt install ros-${ROS_DISTRO}-mavros
sudo ros2 run mavros install_geographiclib_datasets.sh
ros2 launch mavros px4.launch

CHANGELOG

Changelog for package mavros

2.17.0 (2026-11-11)

  • Merge pull request #2358 from agyoungs/sys-time-match-timesync-replies sys_time: use only the FCU's replies to our own TIMESYNC requests

  • plugin: move AddressedToUsAndOk back to the mission base This reverts commit 1474e415. sys_time was the only other user and now checks the target ids in its handler. The filter knows only the common dialect, so it should not be offered as a generic one. Co-Authored-By: Claude Fable 5.2 <<noreply@anthropic.com>>

  • sys_time: check TIMESYNC target ids in the handler PX4 v1.14 - v1.17 has the target fields in TIMESYNC, but leaves them uninitialised in its replies, so a filter on them may drop the replies to our own requests. Go back to SystemAndOk and check in the handler:

    • a request is answered only if it is addressed to us or broadcast;

    - a reply is matched by ts1 only, its target fields are not checked. Co-Authored-By: Claude Fable 5.2 <<noreply@anthropic.com>>

  • Merge pull request #2366 from mavlink/ftp-burst-followup ftp: follow-up fixes for burst sequence window (#2361)

  • ftp: do not skip a sequence window after an unsupported burst A kErrUnknownCommand NAK is the only reply to a burst request, so there is no stream to separate from. Clear the reservation before falling back to kCmdReadFile, FCUs without burst support keep plain +1 sequencing. Tests, follow-up to #2361:

    - the fallback test asserts the sent sequence numbers and no replays, it passed without the plugin change before;

    - the late EOF test no longer uses the reply cache, so it does not duplicate close_after_final_burst_is_not_replayed_as_eof;

    - the wraparound test puts the burst stream on the 16-bit boundary: last data packet at 65535, cached EOF NAK at 0, close past the window. Co-Authored-By: Claude Fable 5.2 <<noreply@anthropic.com>>

  • Merge pull request #2361 from AscendEngineering/fix/ftp-burst-failed-close ftp: Standard FTP read after burst FTP read sequence error

  • Fixed Standard FTP read after burst FTP read

  • test: sys_time: check ignored TIMESYNC messages with a valid one after The tests that a request or reply is ignored waited a fixed time and then checked nothing came out, so on a slow machine they could pass without the plugin having acted. The plugin handles an injected message before inject() returns and its replies and statuses arrive in order, so each such check now sends a valid message after the ignored one and checks that the valid one's result is the only one. The fixed sleep in inject() goes, and the positive checks compare the remote timestamp rather than a count. Each check fails when the behaviour it guards is removed: any reply component accepted, ts1 not checked, SystemAndOk instead of AddressedToUsAndOk, or a pending request not removed once used. Co-Authored-By: Claude Opus 5.5 <<noreply@anthropic.com>>

  • sys_time: address review: clock steps, component 0, test helpers

    - Record each request's ts1 as sent. Forcing ts1 to increase kept it above an old maximum after our clock stepped back (sim time with a SITL restart, an NTP step), so every RTT underflowed and was rejected until the clock caught up. Duplicate ts1 values are harmless, as each reply takes one pending entry.

    - Treat target component 0 as any component. Warn (throttled) when a reply to one of our requests comes from another component, the case a misconfigured target component produces.

    - Test helpers: convert_message() zero-initialises the message and sets msgid and len, so the target-field checks no longer read garbage, and capture_sink() returns a CaptureBuffer read through a locked snapshot().

    - Note in AddressedToUsAndOk that it only knows common-dialect messages. New tests: target component 0, and sync after the clock steps back; both fail on the previous commit. Co-Authored-By: Claude Opus 5.5 <<noreply@anthropic.com>>

  • sys_time: use only the FCU's replies to our own TIMESYNC requests Any TIMESYNC with tc1 > 0 from the target system counted as a reply to our request, whatever its component and ts1. When other components also timesync with the FCU (a GCS, companion apps), the FCU's replies to them reach us too, each a sample against another clock: high-deviation rejections and "Time jump detected" resets. A reply now counts only if it comes from the target component and echoes the ts1 of one of our pending requests, each used once.

MAVROS

MAVLink extendable communication node for ROS with proxy for Ground Control Station (e.g. [QGroundControl][qgc]).

ROS API documentation moved to [wiki.ros.org][wiki].

Features

  • Communication with autopilot via serial port, UDP or TCP (e.g. [PX4 Pro][px4] or [ArduPilot][apm])
  • Internal proxy for Ground Control Station (serial, UDP, TCP)
  • Plugin system for ROS-MAVLink translation
  • Parameter manipulation tool
  • Waypoint manipulation tool
  • PX4Flow support (by [mavros_extras][mrext])
  • OFFBOARD mode support
  • Geographic coordinates conversions.

Limitations

Only for Linux. Depends on [Boost library][boost], GCC 4.8+ (C++11 support). Catkin build system required.

This package are dependent on [ros-*-mavlink][mlwiki] build from [mavlink-gbp-release][mlgbp]. It exists in ROS package index and usually updates each month.

Connection URL

Connection defined by URL, you can use any supported type for FCU and GCS.

Supported schemas:

  • Serial: /path/to/serial/device[:baudrate]
  • Serial: serial:///path/to/serial/device[:baudrate][?ids=sysid,compid]
  • Serial with hardware flow control: serial-hwfc:///path/to/serial/device[:baudrate][?ids=sysid,compid]
  • UDP: udp://[bind_host][:port]@[remote_host[:port]][/?ids=sysid,compid]
  • UDP broadcast until GCS discovery: udp-b://[bind_host][:port]@[:port][/?ids=sysid,compid]
  • UDP broadcast (permanent): udp-pb://[bind_host][:port]@[:port][/?ids=sysid,compid]
  • TCP client: tcp://[server_host][:port][/?ids=sysid,compid]
  • TCP server: tcp-l://[bind_host][:port][/?ids=sysid,compid]

Note:

  • Ids from URL overrides value given by system_id & component_id parameters.
  • bind_host - default 0.0.0.0 - i.e. IP4 ANY
  • UDP default ports: 14555 @ 14550
  • UDP remote address updated every time with incoming packet on bind port.
  • TCP default port: 5760

Coordinate frames

MAVROS does translate Aerospace NED frames, used in FCUs to ROS ENU frames and vice-versa. For translate airframe related data we simply apply rotation 180° about ROLL (X) axis. For local we apply 180° about ROLL (X) and 90° about YAW (Z) axes. Please read documents from issue #473 for additional information.

All the conversions are handled in src/lib/ftf_frame_conversions.cpp and src/lib/ftf_quaternion_utils.cpp and tested in test/test_frame_conversions.cpp and test/test_quaternion_utils.cpp respectively.

Related issues: [#49 (outdated)][iss49], [#216 (outdated)][iss216], [#317 (outdated)][iss317], [#319 (outdated)][iss319], [#321 (outdated)][iss321], [#473][iss473]. Documents: [Frame Conversions][iss473rfc], [Mavlink coordinate frames][iss473table].

MAVROS also allows conversion of geodetic and geocentric coordinates through [GeographicLib][geolib] given that:

  • geographic_msgs and NatSatFix.msg require the LLA fields to be filled in WGS-84 datum, meaning that the altitude should be the height above the WGS-84 ellipsoid. For that, a conversion from the height above the geoid (AMSL, considering the egm96 geoid model) to height above the WGS-84 ellipsoid, and vice-versa, is available and used in several plugins;
  • According to ROS REP 105, the earth frame should be propagated in ECEF (Earth-Centered, Earth-Fixed) local coordinates. For that, the functionalities of GeographicLib are used in order to allow conversion from geodetic coordinates to geocentric coordinates;
  • The translation from GPS coordinates to local geocentric coordinates require the definition of a local origin on the map frame, in ECEF, and calculate the offset to it in ENU. All the conversions are supported by GeographicLib classes and methods and implemented in the global_position plugin.

Programs

mavros_node – main communication node

Main node. Allow disable GCS proxy by setting empty URL.

Run example (autopilot connected via USB at 921600 baud, GCS running on the host with IP 172.16.254.1):

rosrun mavros mavros_node _fcu_url:=/dev/ttyACM0:921600 _gcs_url:=udp://@172.16.254.1

gcs_bridge – additional proxy

Allows you to add a channel for GCS. For example if you need to connect one GCS for HIL and the second on the tablet.

CHANGELOG

Changelog for package mavros

1.5.1 (2021-01-04)

  • Fix tests for renaming of ECEF cases Introduced in 6234af29
  • Initialise message structures Uninitialised Mavlink 2 extension fields were sent if the fields were not later set. Initialising the fields to zero is the default value for extension fields and appears to the receiver as though sender is unaware of Mavlink 2. Instances were found with regex below, more may exist: mavlink::[\^:]+::msg::[\^:={]+ ?[\^:={]*;
  • Contributors: Rob Clarke

1.5.0 (2020-11-11)

  • mavros/sys_status: Fill flight_custom_version field
  • mavros: Add override specifiers
  • mavros: Move ECEF tf enums to separate enum class This avoids a bunch of unhandled switch cases, and should improve type safety a bit.
  • Contributors: Morten Fyhn Amundsen

1.4.0 (2020-09-11)

  • mavros: use mavlink::minimal:: after incompatible changes in mavlink package Incompatible change: https://github.com/mavlink/mavlink/pull/1463 Fix: #1483, https://github.com/mavlink/mavlink/issues/1474
  • fixes based on vooon's review
  • fix issue what we couldn't set real parameters to 0.0 in mavros
  • Add error message
  • Fixed compilation error: publish std_msgs::String, not std::string for gcs_ip
  • Dispatch GCS IP address
  • Contributors: Artem Batalov, Marcelino, Morten Fyhn Amundsen, Vladimir Ermakov, Øystein Skotheim

1.3.0 (2020-08-08)

  • fake_gps.cpp: implement speed accuracy
  • fake_gps.cpp: Add mocap_withcovariance configuration parameter
  • fake_gps.cpp: add initial support for GPS_INPUT MAVLink message
  • apm.launch: Avoid warning: Warning: You are using <arg> inside an <include> tag with the default=XY attribute - which is superfluous. Use value=XY instead for less confusion. Attribute name: respawn_mavros
  • Added support for MavProxy parameter file format
  • Ignore read-only parameters and statistics parameters in push operations
  • fix indentation
  • transform based on coordinate_frame
  • wind plugin: fix ArduPilot wind transformation
  • Contributors: Ben Wolsieffer, Dr.-Ing. Amilcar do Carmo Lucas, Yuan, Yuan Xu

1.2.0 (2020-05-22)

  • has_capability only works for enums
  • Uncrustify
  • Reworked Waypoint plugin to use capabilities_cb Additionally added helper functions has_capability and has_capabilities so that people can use either ints or enums to check if the UAS has a capability. This might make accepting capabilities as a parameter moot though.
  • Added alias for capabilities enum to UAS
  • Added alias for capabilities enum to UAS
  • Added a capabilities change cb queue Plugins can now write functions that they add to the capabilities_cb_vec. These functions will be called only when there is a change to the capabilities themselves not whenever the known status of the fcu_capabilities change. These functions should have a parameter of type mavlink::common::MAV_PROTOCOL_CAPABILITY which is essentially just a uint64_t however being more opinionated is helpful when looking for what the canonical enum names are in the mavlink project header files.
  • Uncrustify
  • Fixed Removed Uncrustify Option I'm not sure why this didn't break when I ran uncrustify previously but it seems that the align_number_left option was removed a while ago with this merge request but I may be mistaken https://github.com/uncrustify/uncrustify/pull/1393 I replaced it which align_number_right=true since it seems to be the inverse of align_number_left=true.
  • Removed deprecated MAV_FRAME values
  • Removed use of variant in favor of templates Since ROS messages are now the storage type in the node, providing to and from conversion functions is sufficient and can be better expressed with function templates.
  • Encode factor returns double
  • Changed encoding factor cog code
  • Uncrustify changes
  • Added new parameter to config.yamls
  • Updated waypoint plugin to support MISSION_ITEM_INT These changes add a new parameter use_mission_item_int, which allows users to prefer the old behavior. These changes also verify that the flight controller supports _INT messages since APM only sends REQUEST_ITEM messages even though it accepts _INT items back. This commit is functional and tested with the APM stack only. PX4 sitl jmavsim threw: WP: upload failed: Command is not supported. FCU: IGN MISSION_ITEM: Busy

MAVROS

MAVLink extendable communication node for ROS 2.

It provides communication with the autopilot via serial port, UDP or TCP (e.g. PX4 or ArduPilot), an internal proxy for a Ground Control Station, a plugin system for ROS-MAVLink translation, OFFBOARD mode support, and geographic coordinate conversions.

Only for Linux.

The ROS API (topics, services, parameters) of every plugin is documented in the plugin reference and the full documentation.

The transport library is split into the standalone libmavconn package, which is usable outside ROS.

Quick start

sudo apt install ros-${ROS_DISTRO}-mavros
sudo ros2 run mavros install_geographiclib_datasets.sh
ros2 launch mavros px4.launch

CHANGELOG

Changelog for package mavros

2.17.0 (2026-11-11)

  • Merge pull request #2358 from agyoungs/sys-time-match-timesync-replies sys_time: use only the FCU's replies to our own TIMESYNC requests

  • plugin: move AddressedToUsAndOk back to the mission base This reverts commit 1474e415. sys_time was the only other user and now checks the target ids in its handler. The filter knows only the common dialect, so it should not be offered as a generic one. Co-Authored-By: Claude Fable 5.2 <<noreply@anthropic.com>>

  • sys_time: check TIMESYNC target ids in the handler PX4 v1.14 - v1.17 has the target fields in TIMESYNC, but leaves them uninitialised in its replies, so a filter on them may drop the replies to our own requests. Go back to SystemAndOk and check in the handler:

    • a request is answered only if it is addressed to us or broadcast;

    - a reply is matched by ts1 only, its target fields are not checked. Co-Authored-By: Claude Fable 5.2 <<noreply@anthropic.com>>

  • Merge pull request #2366 from mavlink/ftp-burst-followup ftp: follow-up fixes for burst sequence window (#2361)

  • ftp: do not skip a sequence window after an unsupported burst A kErrUnknownCommand NAK is the only reply to a burst request, so there is no stream to separate from. Clear the reservation before falling back to kCmdReadFile, FCUs without burst support keep plain +1 sequencing. Tests, follow-up to #2361:

    - the fallback test asserts the sent sequence numbers and no replays, it passed without the plugin change before;

    - the late EOF test no longer uses the reply cache, so it does not duplicate close_after_final_burst_is_not_replayed_as_eof;

    - the wraparound test puts the burst stream on the 16-bit boundary: last data packet at 65535, cached EOF NAK at 0, close past the window. Co-Authored-By: Claude Fable 5.2 <<noreply@anthropic.com>>

  • Merge pull request #2361 from AscendEngineering/fix/ftp-burst-failed-close ftp: Standard FTP read after burst FTP read sequence error

  • Fixed Standard FTP read after burst FTP read

  • test: sys_time: check ignored TIMESYNC messages with a valid one after The tests that a request or reply is ignored waited a fixed time and then checked nothing came out, so on a slow machine they could pass without the plugin having acted. The plugin handles an injected message before inject() returns and its replies and statuses arrive in order, so each such check now sends a valid message after the ignored one and checks that the valid one's result is the only one. The fixed sleep in inject() goes, and the positive checks compare the remote timestamp rather than a count. Each check fails when the behaviour it guards is removed: any reply component accepted, ts1 not checked, SystemAndOk instead of AddressedToUsAndOk, or a pending request not removed once used. Co-Authored-By: Claude Opus 5.5 <<noreply@anthropic.com>>

  • sys_time: address review: clock steps, component 0, test helpers

    - Record each request's ts1 as sent. Forcing ts1 to increase kept it above an old maximum after our clock stepped back (sim time with a SITL restart, an NTP step), so every RTT underflowed and was rejected until the clock caught up. Duplicate ts1 values are harmless, as each reply takes one pending entry.

    - Treat target component 0 as any component. Warn (throttled) when a reply to one of our requests comes from another component, the case a misconfigured target component produces.

    - Test helpers: convert_message() zero-initialises the message and sets msgid and len, so the target-field checks no longer read garbage, and capture_sink() returns a CaptureBuffer read through a locked snapshot().

    - Note in AddressedToUsAndOk that it only knows common-dialect messages. New tests: target component 0, and sync after the clock steps back; both fail on the previous commit. Co-Authored-By: Claude Opus 5.5 <<noreply@anthropic.com>>

  • sys_time: use only the FCU's replies to our own TIMESYNC requests Any TIMESYNC with tc1 > 0 from the target system counted as a reply to our request, whatever its component and ts1. When other components also timesync with the FCU (a GCS, companion apps), the FCU's replies to them reach us too, each a sample against another clock: high-deviation rejections and "Time jump detected" resets. A reply now counts only if it comes from the target component and echoes the ts1 of one of our pending requests, each used once.

MAVROS

MAVLink extendable communication node for ROS with proxy for Ground Control Station (e.g. [QGroundControl][qgc]).

ROS API documentation moved to [wiki.ros.org][wiki].

Features

  • Communication with autopilot via serial port, UDP or TCP (e.g. [PX4 Pro][px4] or [ArduPilot][apm])
  • Internal proxy for Ground Control Station (serial, UDP, TCP)
  • Plugin system for ROS-MAVLink translation
  • Parameter manipulation tool
  • Waypoint manipulation tool
  • PX4Flow support (by [mavros_extras][mrext])
  • OFFBOARD mode support
  • Geographic coordinates conversions.

Limitations

Only for Linux. Depends on [Boost library][boost], GCC 4.8+ (C++11 support). Catkin build system required.

This package are dependent on [ros-*-mavlink][mlwiki] build from [mavlink-gbp-release][mlgbp]. It exists in ROS package index and usually updates each month.

Connection URL

Connection defined by URL, you can use any supported type for FCU and GCS.

Supported schemas:

  • Serial: /path/to/serial/device[:baudrate]
  • Serial: serial:///path/to/serial/device[:baudrate][?ids=sysid,compid]
  • Serial with hardware flow control: serial-hwfc:///path/to/serial/device[:baudrate][?ids=sysid,compid]
  • UDP: udp://[bind_host][:port]@[remote_host[:port]][/?ids=sysid,compid]
  • UDP broadcast until GCS discovery: udp-b://[bind_host][:port]@[:port][/?ids=sysid,compid]
  • UDP broadcast (permanent): udp-pb://[bind_host][:port]@[:port][/?ids=sysid,compid]
  • TCP client: tcp://[server_host][:port][/?ids=sysid,compid]
  • TCP server: tcp-l://[bind_host][:port][/?ids=sysid,compid]

Note:

  • Ids from URL overrides value given by system_id & component_id parameters.
  • bind_host - default 0.0.0.0 - i.e. IP4 ANY
  • UDP default ports: 14555 @ 14550
  • UDP remote address updated every time with incoming packet on bind port.
  • TCP default port: 5760

Coordinate frames

MAVROS does translate Aerospace NED frames, used in FCUs to ROS ENU frames and vice-versa. For translate airframe related data we simply apply rotation 180° about ROLL (X) axis. For local we apply 180° about ROLL (X) and 90° about YAW (Z) axes. Please read documents from issue #473 for additional information.

All the conversions are handled in src/lib/ftf_frame_conversions.cpp and src/lib/ftf_quaternion_utils.cpp and tested in test/test_frame_conversions.cpp and test/test_quaternion_utils.cpp respectively.

Related issues: [#49 (outdated)][iss49], [#216 (outdated)][iss216], [#317 (outdated)][iss317], [#319 (outdated)][iss319], [#321 (outdated)][iss321], [#473][iss473]. Documents: [Frame Conversions][iss473rfc], [Mavlink coordinate frames][iss473table].

MAVROS also allows conversion of geodetic and geocentric coordinates through [GeographicLib][geolib] given that:

  • geographic_msgs and NatSatFix.msg require the LLA fields to be filled in WGS-84 datum, meaning that the altitude should be the height above the WGS-84 ellipsoid. For that, a conversion from the height above the geoid (AMSL, considering the egm96 geoid model) to height above the WGS-84 ellipsoid, and vice-versa, is available and used in several plugins;
  • According to ROS REP 105, the earth frame should be propagated in ECEF (Earth-Centered, Earth-Fixed) local coordinates. For that, the functionalities of GeographicLib are used in order to allow conversion from geodetic coordinates to geocentric coordinates;
  • The translation from GPS coordinates to local geocentric coordinates require the definition of a local origin on the map frame, in ECEF, and calculate the offset to it in ENU. All the conversions are supported by GeographicLib classes and methods and implemented in the global_position plugin.

Programs

mavros_node – main communication node

Main node. Allow disable GCS proxy by setting empty URL.

Run example (autopilot connected via USB at 921600 baud, GCS running on the host with IP 172.16.254.1):

rosrun mavros mavros_node _fcu_url:=/dev/ttyACM0:921600 _gcs_url:=udp://@172.16.254.1

gcs_bridge – additional proxy

Allows you to add a channel for GCS. For example if you need to connect one GCS for HIL and the second on the tablet.

MAVROS

MAVLink extendable communication node for ROS with proxy for Ground Control Station (e.g. [QGroundControl][qgc]).

ROS API documentation moved to [wiki.ros.org][wiki].

Features

  • Communication with autopilot via serial port, UDP or TCP (e.g. [PX4 Pro][px4] or [ArduPilot][apm])
  • Internal proxy for Ground Control Station (serial, UDP, TCP)
  • Plugin system for ROS-MAVLink translation
  • Parameter manipulation tool
  • Waypoint manipulation tool
  • PX4Flow support (by [mavros_extras][mrext])
  • OFFBOARD mode support
  • Geographic coordinates conversions.

Limitations

Only for Linux. Depends on [Boost library][boost], GCC 4.8+ (C++11 support). Catkin build system required.

This package are dependent on [ros-*-mavlink][mlwiki] build from [mavlink-gbp-release][mlgbp]. It exists in ROS package index and usually updates each month.

Connection URL

Connection defined by URL, you can use any supported type for FCU and GCS.

Supported schemas:

  • Serial: /path/to/serial/device[:baudrate]
  • Serial: serial:///path/to/serial/device[:baudrate][?ids=sysid,compid]
  • Serial with hardware flow control: serial-hwfc:///path/to/serial/device[:baudrate][?ids=sysid,compid]
  • UDP: udp://[bind_host][:port]@[remote_host[:port]][/?ids=sysid,compid]
  • UDP broadcast until GCS discovery: udp-b://[bind_host][:port]@[:port][/?ids=sysid,compid]
  • UDP broadcast (permanent): udp-pb://[bind_host][:port]@[:port][/?ids=sysid,compid]
  • TCP client: tcp://[server_host][:port][/?ids=sysid,compid]
  • TCP server: tcp-l://[bind_host][:port][/?ids=sysid,compid]

Note:

  • Ids from URL overrides value given by system_id & component_id parameters.
  • bind_host - default 0.0.0.0 - i.e. IP4 ANY
  • UDP default ports: 14555 @ 14550
  • UDP remote address updated every time with incoming packet on bind port.
  • TCP default port: 5760

Coordinate frames

MAVROS does translate Aerospace NED frames, used in FCUs to ROS ENU frames and vice-versa. For translate airframe related data we simply apply rotation 180° about ROLL (X) axis. For local we apply 180° about ROLL (X) and 90° about YAW (Z) axes. Please read documents from issue #473 for additional information.

All the conversions are handled in src/lib/ftf_frame_conversions.cpp and src/lib/ftf_quaternion_utils.cpp and tested in test/test_frame_conversions.cpp and test/test_quaternion_utils.cpp respectively.

Related issues: [#49 (outdated)][iss49], [#216 (outdated)][iss216], [#317 (outdated)][iss317], [#319 (outdated)][iss319], [#321 (outdated)][iss321], [#473][iss473]. Documents: [Frame Conversions][iss473rfc], [Mavlink coordinate frames][iss473table].

MAVROS also allows conversion of geodetic and geocentric coordinates through [GeographicLib][geolib] given that:

  • geographic_msgs and NatSatFix.msg require the LLA fields to be filled in WGS-84 datum, meaning that the altitude should be the height above the WGS-84 ellipsoid. For that, a conversion from the height above the geoid (AMSL, considering the egm96 geoid model) to height above the WGS-84 ellipsoid, and vice-versa, is available and used in several plugins;
  • According to ROS REP 105, the earth frame should be propagated in ECEF (Earth-Centered, Earth-Fixed) local coordinates. For that, the functionalities of GeographicLib are used in order to allow conversion from geodetic coordinates to geocentric coordinates;
  • The translation from GPS coordinates to local geocentric coordinates require the definition of a local origin on the map frame, in ECEF, and calculate the offset to it in ENU. All the conversions are supported by GeographicLib classes and methods and implemented in the global_position plugin.

Programs

mavros_node – main communication node

Main node. Allow disable GCS proxy by setting empty URL.

Run example (autopilot connected via USB at 921600 baud, GCS running on the host with IP 172.16.254.1):

rosrun mavros mavros_node _fcu_url:=/dev/ttyACM0:921600 _gcs_url:=udp://@172.16.254.1

gcs_bridge – additional proxy

Allows you to add a channel for GCS. For example if you need to connect one GCS for HIL and the second on the tablet.
