Precise Navigation Over Wide Areas Using Satellites

Abstract

A class of satellite-based radio navigation systems is described which can offer precise, near global position-fixing capability to a wide variety of users. The system operation, based on one-way pseudo-ranging by a user to four satellites in 24-hour inclined, elliptical orbits, is described. Ground coverage and the factors influencing accuracy are discussed.
