Abstract
A method of providing accurate position, navigation, and timing information comprising the steps of providing at least four transceiver devices, providing an auxiliary GPS device, and providing a receiver GPS device. Each transceiver devices receives a plurality of GPS signals from a plurality of GPS satellites, and calculates a transceiver position and transceiver velocity vector. The transceiver position, transceiver velocity vector, and GPS signal are repackaged at each transceiver into a first spread signal structure, which is transmitted from each transceiver as a first GPS-like signal. The GPS-like signal is received at an auxiliary GPS device, which generates a simulated GPS signal. This simulated GPS signal is then output and received by a simulated GPS device.
