Assured Positioning, Navigation and Timing (PNT)
Abstract
The current Global Positioning System (GPS) capability is a fixed frequency system susceptible to electronic warfare and field environments (e.g. urban, dense vegetation). Assured Positioning, Navigation and Timing (APNT) provides Army ground maneuver forces access to assured PNT under conditions that may be limited or denied (jammed and spoofed) and in accordance with National Defense Authorization Act guidance. APNT products are ruggedized tactical systems that enable Army forces the ability to shoot, move, communicate, thereby allowing forces to maneuver from operational and strategic distances to close with, destroy, and exploit the enemy with sufficient combat power, tempo, and momentum. APNT addresses two critical capability gaps: Access and Integrity. Access is the ability to retrieve accurate PNT information in a contested Electronic Warfare/Cyber environment. Integrity is the ability to trust the PNT information. PNT is a critical enabler of many Army Maneuver, Fires, and Command and Control systems that are dependent on accurate Position and Timing, and a foundational Multi-Domain Battle capability to support: calibrated force posture (position and maneuver across strategic distances); multi-domain formations (operate in contested spaces against near-peer adversaries); convergence (continuous integration of capabilities in all domains). Joint Requirements Oversight Council Memo (JROCM) 049-10, dated 05 April 2010, approved the PNT Assurance Initial Capabilities Document and designated the Army as the Lead Component for Assured PNT. Army Futures Command approved the Mounted APNT System (MAPS) Directed Requirement (DR) on 31 January 2019. The Dismounted APNT System (DAPS) Directed Requirement was approved 19 March 2019. The Alternative Navigation (ALTNAV) Directed Requirement was approved in 10 August 2019. On 12 September 2020, the Army Requirements Oversight Council (AROC) approved the MAPS Capabilities Development Document (CDD). DAPS CDD is planned to be approved in Fiscal Year (FY) 2021. Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance (C5ISR) Modular Open Suite of Standards (CMOSS) in support of House Report 116-442, 2020 efforts will prototype modular cards and software according to the Modular Open System Architecture (MOSA) standards, for future modernization and new weapons systems. In addition, the CMOSS Mounted Form Factor Abbreviated Capabilities Development Document (A-CDD) was approved in 2nd Quarter FY 2021. APNT consists of four Projects; (BV4) Area Protection and ALTNAV Technology Development, (ED5) Assured PNT, (EH8) Dismounted APNT System (DAPS), and (EJ2) MAPS. (BV4) - The Area Protection and Alt Nav Technology Development project supports the transition of technologies from industry, academia, and government Science & Technology organizations, and consequent development of alternative and complementary PNT technologies for integration into MAPS and Dismounted APNT System (DAPS). Area Protection & ALTNAV Technologies will be developed in order to demonstrate Modular Open System Architecture (MOSA), CMOSS, ALTNAV, Science & Technology emerging complementary PNT, and net-enabled GPS solutions to provide Radio Frequency (RF) and non-RF threat mitigation. (ED5) - The Assured PNT project funding line is for Resiliency and Software Assurance Measures (RSAM) software upgrades to legacy military GPS receivers. Additionally, the Assured PNT project supports the development of Assured PNT enablers, network integration and certification of ALTNAV enterprise build out (ground). Completes critical timing and equipment upgrades. These connections, upgrades, and certification activities are critical to operationalizing ALTNAV as an effective and suitable contingency source of PNT data in the event GPS is denied/degraded. (EH8) - The Dismounted APNT System (DAPS) will provide Dismounted Soldiers, Commanders, and Systems the resilient, survivable, Military Code (M-Code) capable timing and position data to effectively engage targets, share data across the network and conduct mission command in degraded or denied GPS environments. (EJ2) - The MAPS is a platform-mounted, ruggedized tactical PNT system that provides electronic protection capabilities to provide Army forces the ability to move, shoot, communicate, and provide situational awareness in degraded or denied GPS environments.
