LOW-ORBIT NAVIGATION CONCEPTS

Peer Reviewed

Abstract: Low-orbit, inexpensive navigation satellite concepts applicable to civil aviation are developed as an alternative to GPS. Details are provided on orbits, signal structure, positioning software, power budget, and estimated costs and risks. Comprehensive error analysis indicates that a 2 dRMS accuracy of approximately 85 m is achievable, and that the system is fault-tolerant. Rough estimates indicate that the satellite configuration will cost about $300 million.
