Generalized high performance navigation system

摘要

A generalized high performance navigation system is provided using low earth orbit (LEO) satellites. In one embodiment, a method of performing navigation includes receiving a LEO signal from a LEO satellite. The method also includes decoding a navigation signal from the LEO signal. The method further includes receiving first and second ranging signals from first and second ranging sources, respectively. In addition, the method includes determining calibration information associated with the first and second ranging sources. The method also includes calculating a position using the navigation signal, the first and second ranging signals, and the calibration information.
