27 May 1996 GPS-aided retrotraverse for unmanned ground vehicles
Author Affiliations +
A computer controlled HMMWV automatically retraces a previously recorded path using navigation data, a process we have termed retrotraverse. A Kalman filter combines the output of two navigation systems, an inertial dead reckoning systems and a differential GPS both with and without carrier phase detection. During retrotraverse, the mobility controller uses a velocity controller and pure pursuit steering. Obstacles such as another vehicle can be detected with a laser range imaging device.
