Assured Positioning, Navigation and Timing

The Assured Positioning, Navigation, and Timing (APNT) program is a crucial initiative by the Army to ensure reliable access to positioning, navigation, and timing information for ground maneuver forces. The primary goal is to provide assured PNT capabilities in environments where Global Positioning Systems (GPS) may be compromised due to jamming or spoofing. This initiative supports the Army's modernization priority by addressing capability gaps in access and integrity of PNT data, which are essential for effective maneuver, fires, and command and control systems.

The program includes several key components such as the Dismounted Assured PNT System (DAPS) and the Mounted APNT System (MAPS). DAPS aims to equip dismounted soldiers with M-Code GPS capabilities, ensuring they have accurate timing and position data even in denied environments. The system is designed to support precision targeting, data sharing across networks, and mission command functions.

MAPS focuses on providing mounted platforms with resilient PNT solutions through sensor fusion and anti-jam technologies. This enables combat forces to maintain situational awareness and operational effectiveness. Additionally, the Alternative Navigation (ALTNAV) Enterprise offers a complementary navigation solution that serves as a contingency in case of GPS degradation. This component aligns with guidance to ensure continued operations under challenging conditions.

The program also emphasizes modularity and future-proofing through the development of modular cards and software based on the Modular Open System Approach (MOSA) standards. The APNT program's objectives are centered around enhancing the Army's operational capabilities by ensuring reliable access to critical PNT information across various domains. By integrating advanced technologies and adhering to congressional and Department of Defense guidance, the program seeks to maintain a strategic advantage in contested environments against near-peer adversaries.
