Warfighters require precision and accuracy to execute their missions, which becomes more difficult when GPS is compromised. Collins Aerospace’s next-generation mounted APNT solution, also known as Mounted Assured Positioning, Navigation and Timing System (MAPS) Gen II, maintains the integrity of positioning and timing in GPS-contested environments and keeps up with the pace of current and future enemy threats and technologies. To reduce vehicle system changes, Collins Aerospace also uses a smart, two Line-Replaceable-Unit (LRU) system that cleanly replaces the existing navigation system in the vehicle for easier upgrade and sustainability.

The MAPS Gen II system

Comprised of Collins Aerospace's NavHub™-100 navigation system and Multi-Sensor Antenna System (MSAS-100), the new MAPS Gen II solution brings heightened protection levels against the evolving GPS threats to support multi-domain operations and mitigate the evolving electronic threats that warfighters are facing today. New benefits of our system include Military Code (M-Code) capability and improved levels of reliability through patented Modernized Signal Tracking (MST) that enhances GPS integrity.
