Locata’s technology has received stunning validation by the USAF following a technical demonstration of its high accuracy positioning technology at the White Sands Missile Range in New Mexico in October 2011. Locata established a LocataNet covering 3,500 sq km with just 10 LocataLite transmitters. An aircraft flown by the 746 Test Squadron based at Holloman AFB flew a series of sorties – day and night – during the last week of October.
Post-processing of the data captured by the 746TS showed Locata was able to deliver positioning accuracy to an aircraft flying up to 25,000 ft in altitude and at speeds up to 550 knots, of 6 cm (horizontal) and 15 cm (vertical) – totally autonomous of GPS and without augmentation from any other system – terrestrial or space-based.
The demonstration was part of the development of the USAF’s Ultra High Accuracy Reference System (UHARS). UHARS is the 746th Test Squadron’s next generation reference system, currently under development to meet test and evaluation reference requirements for future navigation and guidance systems. UHARS will provide a highly accurate reference solution for airborne and land-based test vehicles in electronic warfare environments where modernized and legacy GPS signals are jammed from friendly or hostile systems.
