Abstract

The analysis of tracking loops for global navigation satellite systems (GNSS) receivers is often confined to Monte Carlo approaches that can result in long simulation times and a limited number of simulation runs. A different approach based on Semi-Analytic principles is considered here. Matlab® code implementing a Semi-Analytic framework for the fast simulation of GNSS digital tracking loops is presented. The code structure is detailed and two specific examples implementing a standard PLL and the Double Estimator for unambiguous binary offset carrier (BOC) tracking are provided. The code has been organized in a modular way, and can be easily modified for the simulation of different tracking loops.
