Information for OEMs

Support for Remote ID was added in AuterionOS 2.5.5.

Enabling or Disabling Remote ID in APX4

The APX4 parameter COM_PREARM_ODID needs to be enabled in order for the Remote ID preflight check to be enabled. In production builds of APX4 this parameter will be enabled by default and cannot be changed by the pilot. The parameter primarily exists to give developers more control over their vehicle during their development process.
  • COM_PREARM_ODID=0: Remote ID preflight check is disabled and the pilot could arm even when Remote ID is not running correctly.
  • COM_PREARM_ODID=1: Remote ID preflight check is enabled. If Remote ID is not running and healthy, APX4 will deny arming.

Ground Station needs 3D position fix

The Ground Station needs to have access to an accurate 3D GPS position, as this information needs to be broadcast for Remote ID.
The exception are stationary ground stations, which can also broadcast a static position. Auterion Mission Control 1.14.6 does currently not provide a setting to manually specify the GCS position. This feature will be added in the near future.

GCS with Built-in GPS

If the GCS device has a built-in GPS module, no additional steps should be necessary except for validation.

GCS using External GPS

If the ground station is retrofitted with an external GPS module, for example via USB, please adhere the following procedure when testing:
  1. 1.
    Close AMC if it's already open
  2. 2.
    Connect the GPS device
  3. 3.
    Open AMC, then go to the "Settings" menu and the "General" tab. Then scroll down to the section "AutoConnect to the following devices". There make sure that RTK GPS is disabled, select the serial device and configure the baudrate. For the Freefly RTK GPS for example this would be a rate of 57600.
    1. 1.
      On Windows, select the corresponding COM port and baudrate.
    2. 2.
      On Ubuntu, select the corresponding /dev/tty device and configure the baudrate.
The screenshot below shows an exemplary configuration on Ubuntu:
External GPS configuration example

WiFi Requirements

The vehicle needs an exposed WiFi Antenna such that the Remote ID information can be broadcast with a sufficient signal strength. The WiFi radiation pattern has certain requirements as described in the Means of Compliance document (MOC) in Appendix X2.
The WiFi ratiation needs to match certain criteria, such as omnidirectionality and a minimum signal strength at a given distance. We summarized a possible test setup for omnidirectionality that was taken from the MOC.

WiFi Configuration

AuterionOS 2.5.5: WiFi must be disabled for Remote ID to be operational

WiFi Antenna Placement

The WiFi antenna needs to be placed in such a way that a certain signal strength at a specific distance is reached. Refer to the tests Single Point Accuracy Measurement and Omnidirectionality of the broadcast module for more details.
