Robust Enhanced Military GPS (REM-GPS) Receiver for SWAP Constrained HMS Ground Radio Applications

In this Phase II program Mayflower Communications Company, Inc. (Mayflower) proposes to address the extreme size, weight and power and cost (SWAP-C) constraints of HMS Manpack and handheld radio users (such as Rifleman) that demand technological innovations in GPS receiver user equipment to address this need/technology gap. Currently, the JTRS HMS program office is using a commercial C/A code based GPS receiver in the Rifleman Radio under an OSD waiver to provide the situation awareness capability to the Soldiers. The vulnerability of the commercial C/A code receiver to enemy spoofing or jamming of GPS signals is well known, however the SWAP-C constraints of these platforms have precluded inclusion of secure military SAASM GPS receiver for situation awareness. The high unit cost of the current military SAASM GPS receivers, in addition to high power consumption that limits the battery life for the mission, also makes it unaffordable on some of these platforms. Mayflower proposes under this JPEO JTRS SBIR Phase II program to modify, enhance and test its military SAASM GPS receiver products developed under a recently completed program to directly address the SWAP-C needs of JTRS HMS Manpack and Rifleman Radio. The Phase II program will also develop and test software-based jamming/spoofing mitigation techniques to make the receiver product more robust against future hostile threat.
