How is GPS position typically loaded into the INS?

Explanation:
GPS data feeds the INS automatically. The GPS receiver provides position (and velocity and time) that the INS uses to initialize and continuously update its navigation solution. This automatic GPS-aiding helps correct drift in the inertial sensors and speeds up alignment, so the INS doesn’t rely on manual input or only receiving data at takeoff. In typical GPS/INS operation, the data link between the GPS and INS runs in the background, delivering real-time updates that keep the INS accurate throughout the flight.
