Last updated 3 months ago

Firmware Setup

Configure to match the port the ARK SAM GPS is connected to on the flight controller. On the ARK FPV Flight Controller, this is already GPS 1 by default. On the ARK PAB Carrier or ARK Jetson Carrier, this is likely GPS 2 or TELEM/SERIAL 4 depending on which port it is connected to.

Older versions of PX4 will require backported to start the IIS2MDL magnetometer.

Sensor Position Configuration

If the sensor is not centered within the vehicle you will also need to define sensor offsets:

  • The parameters , and can be set to account for the offset of the ARK SAM GPS from the vehicles center of gravity.
