Analysis and Simulation of the GPS-Pseudolite Signals
Global positioning system has been extremely matured in the navigation and positioning field. However, there are still some limits in some aspects and some special application areas, the performance should be improved by other techniques. The pseudolite as a GPS-like ground transmitter provides a new research direction to get a high positioning accuracy and reliability. In this paper, we have described the core technologies of design and simulation realization about the C/A codes of the pseudolite system construction. It is shown that the implementation in Matlab contributes to analyzing of the signal structure and designing the C/A codes and both the simulation results and VHDL realization results are consistent.
