GPS Data Analysis Tools

NAVSYS provides a MATLAB Toolbox that provides GPS signal and receiver tracking simulation. These tools are available as is, or can be customized for your specific needs by NAVSYS.

The GPS Signal Simulation Toolbox simulates the GPS signals and can simulate the effects of signal degradation and dynamics. The receiver's code and carrier tracking loops are fully simulated and the effects of signal degradations can be analyzed. Tracking noise, loss of lock, and cycle slippage can be observed. The signal simulation tool can be used as an analysis aid to assist in test and evaluation of GPS receivers beyond the capability of conventional RF signal simulators that do not provide insight into why different receivers may perform better than others.
