| Abstract: | Several methods to interpolate precise satellite clock bias are introduced.Then,the results obtained by interpolation are compared with that from JPL and other IGS analysis center.Finally,the clock bias results after interpolation are used in the orbit determination for LEOs,and orbit determination accuracies obtained by different methods are analyzed.Using the GPS data of ground tracking stations to estimate satellite clock bias,the estimation accuracy is up to 0.1-0.3 ns.When the GPS satellite clock bias is applied to orbit determination for CHAMP,the accuracy of orbit determination is better than 10cm. |
| Keywords: | precise satellite clock bias interpolation clock bias estimation Precise Point Positioning(PPP) Low Earth Orbits(LEO)determination |
