CHAMP double-difference kinematic POD with ambiguity resolution

Purely kinematic precise orbit determination (POD) was performed for the CHAMP satellite over 11 days in the framework of the CHAMP Orbit Comparison Campaign. For the same period, reduced-dynamic orbits were computed and both types of orbits were independently validated by SLR. The tests with SLR showed that the accuracy of CHAMP reduced-dynamic POD is at the level of 4-5 cm, whereas kinematic orbits have a quality of 5-6 cm. Neither in the kinematic nor in the dynamic orbits a significant SLR range bias could be detected. In adition, we will present results concerning the ambiguity resolution techniques used.
