GNSS code and phase processing techniques in a ground-based mobile altimetry system
Résumé
This article is dedicated to a ground-based altimeter using GNSS signals. This altimeter has been developed in order to be easily movable and able to estimate soil moisture as well, for swamps monitoring. New signal processing techniques are proposed in order to estimate the code, frequency and phase observables of a GNSS signal needed to solve the altimetry problem.
