Abstract
An artificial satellite navigation system and method. The artificial satellite navigation system includes a global positioning system (GPS) receiver, local satellite, and remote satellite absolute navigation units estimating the position and velocity of a local satellite or a remote satellite and bias and drift of a clock in the receiver. A difference calculation unit calculates differences in position and velocity from the local satellite and remote satellite absolute navigation units. A relative navigation unit estimates the relative position and velocity of the local satellite with respect to the remote satellite. The relative navigation unit navigates the local satellite relative to the remote satellite.
