MAPS Gen II Provides APNT in Contested Environments
The US Army has selected Collins Aerospace Systems to provide a next-generation Mounted Assured Positioning, Navigation and Timing System (MAPS) for manned ground vehicles. Designated MAPS Gen II by the Army, the system will maintain the integrity of positioning and timing during operations in GPS-contested environments. Collins Aerospace will deliver new systems to be evaluated for a year, with the potential for fielding up to 8,000 additional vehicles upon completion.
Consisting of the company’s NavHub-100 navigation system and Digital GPS Anti-jam Receiver-100 (DIGAR-100), the new MAPS Gen II solution brings heightened protection levels against the evolving GPS threats that combat elements face on today’s battlefield. New benefits from Collins Aerospace over the existing Army MAPS solution include military code (M-Code) capability and improved levels of reliability through patented Modernized Signal Tracking (MST) that enhances GPS integrity.
The NavHub-100 is the navigational solution that generates and distributes Assured Position, Navigation and Timing (APNT) information to all systems onboard the platform through one device. Additional protection comes with the ground-based DIGAR-100 anti-jam antenna, providing superior immunity in the most severe GPS-challenged environments. To reduce vehicle system changes, Collins Aerospace implemented a smart, two Line-Replaceable-Unit (LRU) system that cleanly replaces the existing navigation system in the vehicle for easier upgrade and sustainability.
“Our warfighters need to be able to execute missions with precision and accuracy, which becomes more difficult when GPS is compromised,” explained Vice President and General Manager, Communication, Navigation and Guidance Solutions, Troy Brunk. “Our mounted APNT solution provides the access and integrity required to keep up with the pace of current and future threats.”
Over more than a decade, Collins Aerospace has delivered over 100,000 anti-jam systems for weapons, aircraft and soldier systems. The DIGAR-100 adapts the proven performance of the company’s airborne and weapons anti-jam systems to meet the demanding requirement on size, weight, power and cost in the ground vehicle market.
