TDMA Datalink Cooperative Navigation Algorithm Based on INS/JTIDS/BA

Position information is very important tactical in large-scale joint military operations. Positioning with datalink time of arrival (TOA) measurements a primary choice when global navigation satellite system (GNSS) not available, members are randomly distributed, only estimates between sources and positioning users may lead to unsatisfactory accuracy, geometry altitude poor. A division multiple address (TDMA) cooperative algorithm based on INS/JTIDS/BA presented this paper. The proposed used revise the errors inertial (INS), clock bias calibrated via round-trip timing (RTT), located height filter. TDMA estimate stated general measurements, predicted states. Weighted horizontal geometric dilution precision (WHDOP) effect accuracy analyzed theory. We simulate distribution (JTIDS) network evaluate performance algorithm. simulation results show that compared an extended Kalman filter (EKF) processes TOA sequentially without performs better.
