Abstract
- 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 that might impair the use of standard methods. Our analysis combines a theoretical assessment of acquisition and tracking thresholds with a performance evaluation by means of a simulation. Three frequency bands are tested (UHF, S and Ka) and an open-source software receiver has been adapted for such a purpose. The results obtained show the potential feasibility of LEO-PNT at baseband level under minimal considerations. [ABSTRACT FROM AUTHOR]
