摘要

This paper introduces the principles of the third-generation Global Positioning Satellite (GPS) system, which is now in the early development phase. The new system has substantial advantages, including the elimination of the Doppler correction and signal tracking circuitry in the receivers. The benefits will be a significantly reduced receiver size and low-maintenance requirements for the satellites. Another objective of the paper is to present a closed-form solution for the GPS geolocation equations that does not depend on range data. Such a solution did not exist previously in the literature. Simulations that characterize the User Equivalent Range Errors in the new system are given.
