Assured Positioning, Navigation, and Timing (APNT) — Dismounted APNT System (DAPS)
Print Friendly, PDF & Email

Updated: 2022



Dismounted Assured Positioning, Navigation, and Timing (APNT) System (DAPS) provides a small, lightweight solution that acquires, protects, and distributes secure PNT to the dismounted Soldier. The first generation of DAPS integrates onto the Nett Warrior (NW) system, distributes PNT information to the NW End-User Device, and replaces the Defense Advanced Global Positioning System (GPS) receiver and commercial GPS receiver on the NW ensemble. It also delivers APNT data through NW Integrated Soldier Power and Data System via wired USB connection. Additionally, DAPS uses NW Conformal Wearable Battery for power and includes modernized M-code receiver and non-GPS augmentation for positioning and navigation integrity.  

DAPS is a potential source of APNT for non-NW systems. Future generations will include a standalone handheld form factor that incorporates complementary PNT, including Alternative Navigation (ALTNAV) and integrates PNT modernization technologies that continually pace/overmatch the threat. 


DAPS provides critical timing and position information to the dismounted Soldier when in GPSdenied or degraded peer/near-peer and Joint All Domain Operations.
