Many of these issues would be addressed by a new ground-based GPS system being developed by an Australian tech firm in collaboration with both NASA and the U.S. Air Force. Locata, headquartered in the Australian Capital Territory city of Bruce, has designed ground-based transmitters which can provide accurate positioning by blanketing a vicinity with radio signals. NASA has seen some success in integrating the technology into unmanned aircraft safety systems while the Air Force is using the radio signal technology to monitor warfare simulation facilities in New Mexico. Signal synchronization timing is about 50 times quicker than conventional GPS and the proximity of these Earth-based sensors to receivers mean that signals can be more easily detected through walls.
