According to US Army Operational Test Command Intelligence Electronic Warfare Test Directorate major Matthew Truax, the mounted assured position navigation and timing system (MAPS) will be integrated across the service’s wheeled and tracked platforms.

The integration supports multi-domain operations by creating high protection levels against emerging GPS threats.

In the first week of testing, soldiers from the 1st Stryker Brigade Combat Team received new equipment training (NET).

This training was intended to help them get acquainted with the MAPS system and user interface and gain an understanding of its capabilities.

The latter part of the test involved providing feedback on the system during operationally realistic missions.

The operations include Call for Fire, Reconnaissance, Quick Reaction Force and Medical Evacuation in a GPS-denied environment.

1st Stryker Brigade Combat Team assistant operations officer captain Christopher Mazeau said: “I’ve never seen what happens to GPS systems when they encounter an electronic warfare (EW) attack.”

MAPS is designed to replace the need for multiple GPS devices on a single platform, supporting command and control.

It also helps in managing EW attacks with the help of an on-board anti-EW antenna.
