Development of DPNS follows a requirement to continuously track soldiers operating in environments that have a complete absence of GPS signals, including tunnels systems, caves, built-up areas, and environments subject to GPS denial or spoofing.

DPNS uses a puck configuration that currently mounts to the boot of the user using a specially designed fixing. The DPNS is transparent to the user, requiring no user input or control and features a GNSS/MIL GPS location engine combined with a built-in barometer that provides location information in full GPS-denied environments. The device includes Bluetooth connectivity used to interface with the chosen bearer system. The DPNS output tracks enable blue force tracking to increase situational awareness, and the system has a built-in haptic feedback capability that is used to provide tangible feedback to the user.
