The tests were completed in mid- November by the Army's Direct Reporting Program Manager Positioning, Navigation and Timing (PM PNT), in collaboration with the Communications-Electronics Research, Development, and Engineering Center (CERDEC). Over the course of eight weeks, anti-jam systems were tested in an anechoic chamber at the Radio-frequency Electromagnetic Compatibility and Antenna Test (REMCAT) facility located at Aberdeen Proving Ground. Ten antenna systems were assessed on their ability to receive GPS satellite signals in contested environments to accurately determine a platform's PNT. The antennas were tested in two configurations: stand alone on a ground plane and mounted on a Stryker vehicle. "PM PNT is dedicated to reducing Warfighter vulnerabilities and increasing PNT resiliency across the battlefield." said Deputy Program Manager Michael Trzeciak. "With the recent testing of anti-jam antenna capabilities, we're one step closer to ensuring our Soldiers have access to trusted GPS signals even when operating in contested environments." Supporting Signal Access GPS signals are inherently weak by the time they reach the earth's surface and susceptible to interference, whether accidental (such as terrain conditions) or intentional (such as jamming by an adversary). The job of anti-jam antennas is to enable continued access to GPS even when impeded or denied. The anti-jam capability is just one of the solutions under development within PM PNT. Assured PNT (A-PNT) is a system of systems solution designed to complement each other. In addition to anti-jam antennas, A-PNT consists of pseudolites, which will provide PNT data to users when GPS satellite signals are distorted or unavailable; dismounted PNT, a scalable and upgradable GPS receiver that will send secure PNT data to the Soldier; and mounted PNT, a scalable and upgradable PNT system for mounting within a platform. The A-PNT program focuses on platform distribution of PNT, scalable PNT architectures that outpace the threat, and the ability to upgrade to future technologies, including Military Code (M-Code). M-Code is expected to further improve anti-jamming capabilities and secure access of Military GPS signals. PM PNT continues to test system capabilities for the A-PNT program in an effort to deliver innovative PNT technologies that will augment and enhance GPS for Soldiers in the field. The A-PNT anti-jam antennas are expected to be available for fielding in fiscal year 2022.

One venue the office will use to obtain Soldier feedback is the Army Warfighting Assessment (AWA) and the Network Integration Evaluation (NIE). The AWA and NIE are Soldier-led assessments of new technologies conducted in a realistic and rigorous operational environment. While the NIE has been held twice a year since 2011 with the 2nd Brigade, 1st Armored Division, the Army is now conducting one annual NIE and one annual AWA and rotating in different units for each exercise. The NIEs focus on formal tests of tactical network and mission command systems, while the AWAs provide an experimental environment with participation from joint and multinational forces to shape requirements and improve capabilities. The first official AWA took place from Oct. 17-28, 2016, at Ft. Bliss, TX, and White Sands Missile Range, NM. It included electronic warfare, cyber and counter-unmanned aircraft systems (C-UAS) scenarios and technologies that will inform Rapid Capabilities Office efforts. Going forward, the Army RCO will continue to lever-age the NIE, AWA, Combat Training Center rotations and other opportunities to expedite the evaluation and feedback process. Emerging Technologies Office Cognizant that the Army doesn't have all the answers, the Rapid Capabilities Office will leverage innovation by other government agencies and industry partners to deliver solutions on an accelerated timeline. Within the Army RCO, there is a dedicated cell called the Emerging Technologies Office (ETO), which will engage directly and continuously to align, understand and drive academia, industry and Science & Technology solutions to near-term and emerging threats with development and demonstration of revolutionary new capabilities. The ETO will host industry days and other forums, and serve as an ombudsman, collaborating with industry to direct efforts towards specific areas of need.
