Abstract:

The essence of satellite geodesy is the resolving baseline intersection in space at observalble time with role as control data. To calculate satellite coordinate, we can use the broadcast ephemeris or precise ephemeris. We have three kinds of precise ephemeris: Ultra-rapid (IGU), Rapid (IGR) and Final (IGS) which depend on what time you receive them. This article show the result of comparing satellite coordinate and satellite’s clock bias from the precise ephemeriss which we presented above. Using Lagrance function to interpolate satellites coordinate at observable time, compare the interpolation results and the results of single point positioning after we used the precise ephemeriss which was mentioned afore.
