Abstract
Disclosed are systems, pseudolite transmitters, receivers, and methods of using the same to navigate. An airborne pseudolite transmitter transmits a first spread spectrum signal indicative of a first fixed location spaced apart from a current actual position of the transmitter. The airborne pseudolite transmitter also transmits a corrections signal indicative of a vector error correction between the first fixed location and the current actual position of the transmitter. A receiver receiving the first spread spectrum signal and the corrections signal calculates its location in response thereto.
