GPS Source developed the U.S. Army's first fielded Assured Positioning, Navigation & Timing (APNT) systems and the first fielded systems utilizing encrypted military signals, known as M-code. M-code provides improved resistance to interference, such as jamming and spoofing, and is part of the DoD's GPS modernization program. Our new family of products is based on DoD and Army defined threat conditions and are scalable, low-cost and easy to install solutions for the great majority of the Army tactical ground vehicle fleet.
Featured APNT Products
The core of our APNT systems, the ED3M PNT Hub, is widely utilized in a variety of ground vehicle applications and is the lead platform for Army and Military Marine Corps for GPS User Equipment (MGUE). Both the Fight Tonight solution and the MRPA Horizon Nuller are available today and in use by either U.S. Army units or friendly forces.
Enhanced D3 M-Code PNT Distribution Hub (ED3M)
The ED3M PNT Hub provides M-code protected GPS data and is widely utilized in a variety of ground vehicle applications.
Fight Tonight Assured PNT System
Our Fight Tonight Assured PNT System is a modification of the MAPS GEN I System, which is the only operational ground Assured PNT System available.
MRPA Horizon-Nulling Active Antenna
The Modified Reception Pattern Antenna (MRPA) is an active Horizon-Nulling GNSS antenna designed to null terrestrial interferences arriving at low elevation angles.
The Mounted Assured PNT System (MAPS) GEN I is a Assured Positioning, Navigation and Timing system that monitors GPS signals for validity and sends the validated data to military devices, even when GPS signals are degraded or denied. The Army has fielded the MAPS GEN I system, making it the first APNT solution to be operationally deployed.
