GPS M'-code and P-code Signal Simulation Using an Open Source Radio Platform

Alison Brown and Bruce Johnson

Abstract:	Current generation military simulators are expensive, increasing costs for GPS test and evaluation for military GPS user equipment developers. Inexpensive commercial GPS simulators are available that use signal simulation, record and playback techniques to test receivers under representative environment, but these commercial record and playback GPS simulators do not have the bandwidth needed to collect or simulate military GPS signals. NAVSYS’ military version of the GNSS Signal Architect software, combined with their implementation of a full bandwidth record and playback capability with their GNSS Signal Generator provides an inexpensive test and evaluation tool for Y, M, P and C/A code (YMCA) receivers. The design of this product is presented in this paper with test results showing its performance with a GPS receiver.
