BALTIMORE – Northrop Grumman Corporation, in partnership with the Air Force Research Laboratory Sensors Directorate, demonstrated the first Software Defined Radio (SDR)-based, M-code enabled GPS receiver on production-capable hardware during a recent flight test. In real-time, the SDR acquired and tracked the modernized GPS military signal, known as M-code, during a live-sky demonstration.
Additionally, Northrop Grumman achieved a security certification milestone by attaining Certification Requirements Review approval for the SDR-based GPS receiver from the GPS Directorate. This milestone constitutes a critical step on the way to fielding an M-code enabled GPS receiver that can be operated in an unclassified environment.
Using a system-on-a-chip SDR approach, in lieu of the traditional fixed application specific integrated circuit (ASIC) design, enabled the platform to make rapid real-time field changes.
