Abstract

Some research results of pseudolite (PL)'s application in air-based information system are presented in this paper. The study include followings: 1) A regional positioning system (RPS) using PL alone. 2) A PL/INS or PL/INS/Optical detector integrated approaching and landing system for aircrafts and MAVs. 3) A PL/INS/Odometer integrated navigation system for ground-moving vehicles. The positioning scheme and models of integration are presented, and some simulation results are introduced and analyzed. Some special problems of the PL signal, such as near-far problem, multipath problem and time synchronization, are also discussed in the paper. The research work is important for navigation/positioning when GPS signal is jammed or is not available. Also, the PL/INS and the PL/INS/Odometer integrated navigation system can be extended to civil airplane approaching and landing system, taking off and landing evaluation system and high precision positioning and fast azimuth determining system.
