DAPS - PM PNT
Dismounted Assured PNT System (DAPS)
DAPS will provide Dismounted Leaders Assured PNT capability in GPS degraded and denied environments by providing GPS integrity and non-GPS sensor augmentation as a nested capability within the Assured PNTA-PNT Ground Domain.
DAPS GEN 1.0 – Nett Warrior Dependent
WHAT IS DAPS?
DAPS replaces the Defense Advanced GPS Receiver (DAGR) and/or commercial GPS on the Nett Warrior Ensemble’s End User Device (EUD), i.e., Smartphone for the Dismounted Leader. DAPS is the primary source for Assured PNT for the Dismounted Leader equipped with Nett Warrior. JPEO Armaments & Ammunition, and PEO Soldier anticipate leveraging DAPS and future DAPS capabilities as part of their Military Code (M-Code) GPS compliance strategy.
Infantry Leaders utilize GPS to support many mission areas. Military equipment can be the subject of enemy electronic attacks, potentially resulting in a loss of situational and location awareness, increasing the risks to Army missions. While DAPS will provide Assured PNT, it will also alert the Dismounted Leader when the GPS solution may not meet mission and or situational needs. DAPS will leverage multiple sensors and timing sources in order to produce the best PNT solution possible within the GPS degraded or denied operational environment. DAPS supports Nett Warrior, Integrated Visual Augmentation System (IVAS), and other Leader platforms’ operational framework by providing IS-GPS-153 standard compliant PNT messages.
Providing Assured PNT to the Dismounted Leader provides a unique challenge. Unlike vehicles, which have the real estate and vehicle power to accommodate robust sensor and antenna suites, DAPS has significant Size, Weight, and Power (SWaP) constraints. Dismounted Leaders, already physically burdened with heavy equipment loads, cannot accept additional power and weight burdens. The DAPS size and weight objective is to be less than that of DAGR.
DAPS is using an iterative Development Operations (DevOps) approach to achieve Assured PNT accuracy, access, and integrity requirements. DAPS plans to develop, deliver, and field capability incrementally in a series of multiple iterations or generations. This strategy provides increased capability over time. Each generation or Gen is designed to inform the next as to what is technically feasible, what is or can be compliant with security, cyber standards of implementation, effective, operationally viable, and finally what keeps pace with the evolving threats. The goal is to achieve an open and modular Dismounted Assured PNT solution in a SWaP constrained environment.
There are seven (7) ongoing DAPS prototyping efforts (3 under GEN 1; and one each under 1.1; 1.2; 1.2 Software Update; and 1.3).
