Abstract:

GNSS measurement from satellite transmission to receiver is influence by many difference sources of error which affected by eccentricity of satellite antenna phase centre. The measurement that we get from satellite antenna phase centre to receiver antenna phase centre. Meanwhile, the coordinate of satellite is computed for the barycentre of satellite. There are some certain deviations between antenna phase centre and geometry barycentre of some satellites. To improve the accuracy of satellite positioning problem, we have to determine the influences of this error. This paper introduces a result from absolute positioning approach considering the correction of satellite antenna phase centre variation.
