Sažetak
A method for kinematic precise orbit determination (POD) based on double-difference algorithms including ambiguity resolution has been developed and first results for the CHAMP satellite are presented here. We show that Melbourne-Wübbena wide-laning together with a bootstrapping strategy for the narrow-lane ambiguity resolution is a promising method in double-difference kinematic POD of low Earth orbiters (LEO) using the ground IGS network and LEO spaceborne GPS receiver. The ambiguity resolution strategy has been checked by comparing the ambiguities of a kinematic with a reduced-dynamic narrow-lane bootstrapping based on a reduced-dynamic orbit parameterization. Moreover, results from simulated and real CHAMP SST data have been analyzed concerning the impact of ambiguity resolution.
