During missile flight tests, a trajectory reference system based on GPS can be used in place of conventional radars. Due to the high precision of GPS trajectory references, it is possible to make use of them in order to evaluate missile inertial measurement unit performance. Before two recent launches of Hepingbaoweizhe (peacekeeper) missiles, GPS transmitters and three wave band antennas were installed on them. On the basis of GPS measurement ranges and range increment data, use was made of kalman wave filter methods to estimate individual IMU errors. Results clearly demonstrated that GPS is superior to radar.
