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.
The Matlab code is available from following *.zip file:
