The portable navigation tool for the US military was found to be effective against jamming

The latest version of wearable equipment that US military soldiers can use to navigate and synchronize maneuvers performs well in the presence of a simulated enemy electronic warfare attack, according to the Pentagon’s independent weapons inspector.

The second-generation Dismounted Assured Positioning, Navigation and Timing System, or DAPS GEN II, is more effective than the legacy Defense Advanced GPS Receiver, or DAGR, amid jamming and spoofing, the Office of the Director of Operational Test and Evaluation said in a report published last month.

The Army in April tapped TRX Systems to produce DAPS GEN II in a deal valued at $402 million. An initial order – more than 700 units and related services – was valued at $14.6 million. The tool succeeds two earlier versions that were rapidly manufactured and issued to troops: GEN I and GEN 1.2. Hundreds of each had been distributed by the end of fiscal 2023.

DAPS GEN II, with its rechargeable battery and upgraded display, is designed to ensure troops understand where they are and where they are headed, even in situations where the signal is obstructed by terrain or debris, or when digital systems are under siege .

Such resilience is needed, defense officials say, as the U.S. prepares for potential struggles against tech-savvy adversaries capable of effective electronic warfare.

During testing, DAPS GEN II improved Soldiers’ situational awareness, supported successful navigation and enabled Soldiers to be “operationally effective,” according to the annual audit. Soldiers, however, asked for additional options for training.

A spokesman for Maryland-based TRX declined to comment on the report. The company is a subsidiary of the ACR Group.
