Assured Positioning, Navigation & Timing Systems
Smarter GPS. Less Recalculating.
When GPS is degraded or denied, our Assured Positioning, Navigation & Timing (APNT) systems enable warfighters to receive validated GPS data, mitigate the effects of electronic warfare attacks, and maintain the precise timing required for their communications and weapons systems.
Featured Systems
General Dynamics Mission Systems subsidiary, GPS Source, Inc., developed the U.S. Army's first fielded 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.
APNT Systems For Ground Vehicles
The U.S. Army's tactical ground vehicle fleet consists of approximately 100,000 total vehicles, many of which are dependent on GPS-based positioning, navigation, and timing (PNT) data.
Our APNT systems are designed to be scalable, low-cost and easy to install solutions for the Army's tactical ground vehicle fleet.
Built on the M-code capable ED3M PNT Hub, our Fight Tonight system is available today and is currently deployed with U.S. Army units in the Indo-Pacific region.
Featured Products
Our APNT products can be integrated into ground vehicles, airborne platforms, artillery systems and more. 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. The core of the Fight Tonight System is the ED3M PNT Hub, which is the lead platform for Army and Military Marine Corps GPS User Equipment, (MGUE), making the ED3M your path to M-code.
HALO Smart Antenna
HALO is our premier Assured PNT system, enabling continued operations in the toughest threat conditions, including GPS denied environments.
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. Fight Tonight is available now and is currently in use in INDOPACOM.
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. MRPA is available now and currently in use in Eastern Europe.
Featured Program: MAPS GEN I
The Mounted Assured PNT System (MAPS) GEN I is an 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. Based on successful installation and performance of these systems during field testing by the Army, the Army’s Project Manager Positioning, Navigation, and Timing ordered the first 2,000 units for operational deployment.
