Over the next 18 months, the air force’s research facility intends to accelerate the progress of resilient, autonomous solutions to support aircraft and helicopter deployments in DDIL overland and over-the-water scenarios.

The US Air Force (USAF) Research Laboratory (AFRL) plans to accelerate the development of autonomous, long-range, resilient navigation capabilities over the next 18 months to improve the operation of aircraft and helicopters in overland and maritime GPS-denied, degraded, intermittent and limited (GPS-DDIL) environments.

Under the Tracking & Resilient Inertial-Derived Estimation for Naval Targets (TRIDENT) programme, the AFRL intends to conduct test flights and experimentation with rotary- and fixed-wing platforms in diverse conditions to collect data and inform the maturation of future solutions and technologies.

As part of this effort, the service awarded a US$2 million Tactical Funding Increase (TACFI) contract
