| Abstract: | Designs of the broadcast ephemeris parameters and algorithms of GPS and GLONASS, two major operational satellite navigation systems today have their respective features. This paper probes the physical background for designing the broadcast ephemeris parameters of the two systems. The features of the parameters in the two systems are compared. Finally, a fitting algorithm for estimating the broadcast ephemeris parameters of GPS is proposed. |
