A parallel GPS satellite positioning algorithm based on broadcast ephemeris

GPS is an all-round, all-weather, real-time satellite navigation and positioning system. GPS satellite positioning based on broadcast ephemeris is to calculate satellite coordinates using relevant parameters obtained from broadcast ephemeris after broadcast ephemeris were analyzed. In real-time navigation and positioning, the speed of GPS satellite positioning will affect the accuracy of the final observation point positioning. However, as GPS is widely used in real life and the data scale of the problem becomes large, the traditional serial satellite positioning algorithm is difficult to meet real-time requirements. In this paper, a parallel GPS satellite positioning algorithm based on broadcast ephemeris is proposed and realized. Through the analysis and comparison of experimental results, it shows that the parallel GPS satellite positioning algorithm can shorten the processing time and improve program efficiency effectively comparing to the traditional serial algorithm. It has practical value.
