High Order DPLL for High Order Doppler Dynamics Tracking

Abstract:	Current GNSS receivers mainly use classical third order tracking loops which are well documented in the literature. However, there is a coming need for fourth order loops to track the signals of future navigation systems that investigate the use of low orbit satellites and frequency bands higher than the L band. Unfortunately, there is a few literatures dealing with the fourth order loops implementation. This paper proposes to investigate and solve the different issues arising when implementing a high order tracking loop.
