Analysis of GNSS-R delay and Doppler tracking errors

The compensation of the delay and Doppler errors using tracking is important to accurately estimate the sea height in spaceborne GNSS-R. This work presents the impacts of the tracking residual errors on the GNSS-R observables, and potential tracking strategies for spaceborne GNSS-R. Tracking error impacts are visually demonstrated by using the P2EPS (PAU/PARIS End-to-end Performance Simulator) spaceborne simulation.
