Just stumbled over this here:

https://directory.eoportal.org/web/e...sensors/uavsar

The design of the UAVSAR focuses on two key challenges:
First, repeat pass measurements need to be taken from flight paths that are nearly identical. This instrument utilizes real-time GPS that interfaces with the platform flight management system (FMS) to confine the repeat flight path to within a 10 m tube over a 200 km course in conditions of calm to light turbulence. The FMS is also referred to as the PPA (Platform Precision Autopilot).

...

For an observation flight, an experimenter may only select waypoints and the desired flight altitude - all other functions of platform control and navigation are being provided by the PPA.
