Defence Trials

GPS Interference Trials

GPS interference trials are undertaken on a regular basis at the WTF by a number of Australian and overseas organisations including the RAAF, the Defence Science and Technology Organisation (DSTO), the Civil Aviation Safety Authority (CASA) and the Air Force Operational Test and Evaluation Center (AFOTEC) of the United States Air Force (USAF). The WTF is one of the few places in the world where such trials are possible without disrupting civilian GPS users. The purpose of the trials is to assess the vulnerability of GPS signals to interference, and to test counter-measures including the use of GPS Jammer Locators and adaptive signal processing techniques. The trials involve ground and airborne elements, with aircraft operations being conducted from Woomera Airfield (picture shows antenna mounting on the control tower at Woomera Airfield).
