Advanced GPS Hybrid Simulator Architecture

Alison Brown and Neil Gerein

Abstract:	NAVSYS has developed an Advanced GPS Hybrid Simulator (AGHS) architecture to address next generation GPS testing issues for the civilian and military markets. The AGHS is a hybrid software, digital and radio frequency (RF) GPS simulator design. In addition to providing digital and RF signal simulation capability, the AGHS can also be used to record and play-back real- world GPS signals from field tests. This paper describes the modular AGHS architecture and its various uses. Digitally created simulation files were created with the system and played back into the NAVSYS Advanced GPS Receiver (AGR). Test results are included that compare the digitally created files to their real-world counterparts showing the precision that can be achieved with the AGHS digital simulation approach. Test data collected during jammer tests conducted at the Electronic Proving Grounds at Ft. Huachuca, Arizona is also presented.
