Analysis of Baseband Algorithms for LEO PNT †

This paper provides an analysis of the impact of transmitter dynamics on baseband algorithms for position, navigation and timing applications using a low Earth orbit constellation. In particular, the acquisition and tracking of signals with high dynamics have larger Doppler and Doppler drift values...
