Position, Navigation, and Timing (PNT)
Abstract
This twelve month project integrated commercial-off-the-shelf (COTS) technologies to provide PNT assurance by using emerging technologies for operations in a global positioning system (GPS) challenged environment. Current Army systems lack a common, integrated PNT capability to enable free maneuver in an anti-assess/area denial (A2/AD) environment. The PNT prototype system uses an enhanced defense GPS receiver (DAGR) device (ED3) with a chip-scale atomic clock (CSAC) accessory module to integrate multiple global navigation satellite system (GNSS) receivers; an embedded chip-scale atomic clock for independent timing; and, a native inertial navigation unit (INU) to provide a cross-checking reference signal. The project developed platform-specific interfaces to integrate these COTS systems into the Abrams, Bradley, Paladin, and Stryker tactical vehicle platforms. Using FY 2017 funds, additional platform integration, safety testing, technical assessment, and operational demonstrations with the warfighter will be completed in FY 2018. The PNT prototype system and demonstrations informed senior Army leadership and transitioned to the Army PM PNT portfolio; Assured PNT, Mounted; and, Anti-Jam Antenna System (AJAS) programs of record.
