Abstract:	In this paper loosely- and tightly-coupled GPS/INS integration is analyzed. The work is related to position and attitude determination of an antenna mounted on an airplane, and the focus is on fulfilling the requirements for footprint chasing in bistatic synthetic aperture radar (SAR) at low cost. The incorporation of additional redundant attitude information derived from GPS by using multiple antennas is considered. Simulation results based on measurements generated with an RF GPS signal simulator and synthetic IMU data are presented.
