The Australian Department of Defense has collaborated with the Joint Navigation Warfare Center (JNWC) to enhance the resilience of GPS devices in contested environments. The JNWC’s mission is to ensure positioning, navigation and timing (PNT) superiority for the Department of Defense and its partners. This joint effort aimed to test the performance of GPS devices under simulated jamming conditions.

Personnel from the Australian Joint Positioning, Navigation and Timing Directorate worked with JNWC experts to evaluate the Defense Advanced GPS Receiver (DAGR), a crucial device used by U.S. and allied forces for navigation across land, sea, and air. The testing took place in an anechoic chamber designed to replicate contested and limited GPS conditions, providing insights to improve the device’s resilience.

The JNWC, recognized for its expertise in navigation warfare, created optimal conditions for this assessment. The specialized chamber allowed them to test the DAGR’s performance in a jamming environment, generating data that can inform the device’s warfighting effectiveness. The team explored solutions such as antennas that enhance jamming resilience, and the findings will be shared with coalition partners to strengthen collective space resilience.

The collaboration serves as a model for international cooperation in addressing security threats, enhancing GPS navigation and timing resilience for allied forces.

TRX Systems, developer of NEON GPS-denied location solutions, has been selected by the U.S. Army to provide a next-generation Dismounted Assured Positioning, Navigation and Timing (PNT) System (DAPS).

The TRX DAPS solution employs a lightweight soldier-worn device that enables dismounted warfighters to successfully conduct operations when operating in GPS challenged, degraded or denied environments.

Military equipment can be the subject of enemy electronic attacks, potentially resulting in a loss of location awareness that can put army missions at increased risk. The TRX DAPS solution alerts the users when their position isn’t reliable and then leverages multiple sensors and timing sources to provide the best soldier position possible within the GPS-degraded operational environment.

The solution — designed to replace the Defense Advanced GPS Receiver (DAGR) — supports both a standalone configuration and integration with the Nett Warrior ensemble. It combines inputs from small, body-worn sensors and other sources to provide assured PNT while meeting the size, weight and power (SWaP) needs of dismounted soldiers already physically burdened with heavy equipment loads.

TRX Systems has delivered GPS-denied location technology to thousands of military, public safety  and security users worldwide.

“Maintaining assured PNT is paramount to the situational awareness of U.S. warfighters in the many conflict zones around the world,” said Carol Politi, president and CEO of TRX Systems. “When initial units are fielded in mid-2022, the TRX DAPS solution will deliver a balance of the highest possible level of integrated PNT capabilities with the smallest package that can be fielded for dismounted warfighters.”

On June 26, the United States Space Force’s Space and Missile Systems Center awarded three separate rapid prototyping agreements to Collins Aerospace, Raytheon Intelligence & Space and the Technology Advancement Group for a total of $41.1 million.

The firm-fixed price agreements are for the development of a basic working prototype of the joint modernized GPS handheld device. The contract provides the government with innovative solutions demonstrated via hardware and software prototype development.

The purpose of this rapid prototyping effort is to produce a joint modernized handheld smaller in size with low power consumption, increased military-code capability, and improved anti-jamming and anti-spoofing capabilities compared to the equipment now used by the military.

4 demonstrations coming

This is the second competitive objective under the current Phase I strategy and is the result of a down-select from five to three vendors. It builds off the first objective of Phase I, which focused on mock-ups and drawings.

These agreements provide for four demonstrations to be held with Army and Marine Corps representatives. The demonstrations give the end users an early opportunity to provide feedback and the ability to influence the final design — ultimately making for a more seamless transition to operations.

“This is the first major update to the military’s GPS handheld device in more than 15 years,” said Col. Clifford Sulham, User Products Division chief.  “The advanced capabilities of this device will allow our airmen, soldiers, sailors and Marines to conduct operations in GPS-challenged environments.”

Sixty-two of the first iteration of mounted anti-jam GPS devices were equipped into light armored vehicles in Germany over the past month, with thousands more scheduled to be installed into U.S. European Command vehicles by 2028, said Army leaders in charge of location data on future battlefields.

The Mounted Assured Precision Navigation & Timing System — known as MAPS — was developed to provide trusted positioning, navigation and timing (PNT) to a platform, such as Stryker vehicles, by pairing a GPS receiver with an anti-jam antenna, said Col. Nickolas Kioutas, PNT project manager.

Read more about MAPS, along with other anti-jam systems, here. Also look for our anti-jam feature coming in the December issue of GPS World magazine.

The electronic technology comes amid the Army’s vision for 2028, to best prepare soldiers for possible warfare with near-peer competitors, who have used electronic warfare to disrupt communications vital to Western forces in recent years.

This year, more than 300 Stryker vehicles, all from the 2nd Cavalry Regiment, are expected to be fielded with MAPS technology, said Willie Nelson, the director of the Army’s Assured PNT Cross-Functional Team.

Upgraded first-generation and second-generation technology is also expected to be unveiled in the future.

The Army also plans to equip armored brigades with the technology, and put MAPS in vehicles such as the Bradley Fighting Vehicle, M1 Abrams tank, and the M109 Paladin self-propelled howitzer. After those “priority vehicles,” the Army will evaluate the mounted device in second-tier priority vehicles, Nelson said.

In the past, armored vehicles have used multiple Defense Advanced GPS receivers, known as DAGR devices.

MAPS replaces multiple DAGR devices with one “really good system,” said Kioutas. The new system uses a chip-scale atomic clock for timing, Selective Availability and Anti-Spoof Module, or SAASM, for GPS, and anti-jamming antenna to distribute PNT information.

In addition, future iterations of MAPS will include non-GPS sensors by fusing GPS with alternate navigation and timing technologies to ensure accurate PNT that soldiers can trust while operating in various threat or denied environments, according to a statement.

A single-point GPS also creates multiple practical benefits for soldiers, such as less maintenance and system key-failing, Kioutas said, adding many of his team’s decisions are based on Soldier feedback, because listening to them today helps prepare them for tomorrow.

Simply put, “MAPS continues to work whenever a GPS signal is weakened or compromised,” he said.

“This is the first technology equipping for the Assured Positioning, Navigation and Timing Cross-Functional Team, and one of the first for Army Futures Command,” Kioutas said.

Nelson noted that they’re “working in parallel with both mounted vehicles and dismounted soldier’s PNT gear.”

Earlier this year, a requirements document for the dismounted soldier’s PNT was signed. Now, currently in the prototyping phase, the latest iteration of a dismounted GPS receiver can send secure PNT data wired or wirelessly, Kioutas said.

“A lot is happening here, a lot of good success,” Nelson said, adding, the most important thing for his team is to get the best equipment to “warfighters on the front lines and getting their feedback rolled back into the next generation.”

Nelson will host a Warrior’s Corner presentation Oct. 15 focusing on the PNT CFT’s Tactical Space Line of Effort, at the Walter E. Washington Convention center in Washington, D.C.
