| Abstract: | On the basis of the orbit character of the LEO satellite and the advantages of definite physical meanings, quickly creating, high precision, fewer parameters of GPS broadcast ephemeris, a new sort of ephemeris parameters for calculating LEO satellite location is designed and analyzed through a example. Some significant comparisons are made between the 15-parameter method of GPS broadcast ephemeris and the designed 25-parameter method, the results show that the designed 25 parameters method has a higher precision for LEO satellite orbit fitting under the same condition. |
| Keywords: | GPS broadcast ephemeris LEO satellite orbit analysis ephemeris parameter fitting precision |
