Abstract
This paper summarizes Doppler positioning and clock modeling. A combined pseudorange and Doppler measurement model is discussed, as well as implications of using Doppler for positioning with the GPS constellation. The combined Doppler and pseudorange algorithm is compared to the standard GPS positioning method, and the constraints on the Doppler positioning will be analyzed. The accuracy of the batched results is compared to GPS positioning. Results for various scenarios with varying satellite visibility are shown. The results of the batched solutions are compared to the performance of standard GPS positioning in different environments.
