Tracking method
First Claim
1. A method of tracking a moving platform having an on-board navigation system, the method comprising:
- using a communication channel to send state data provided by the navigation system of the moving platform to a tracking system state estimator of a processing facility of a ground station having at least one antenna;
collecting additional state data derived from at least one electromagnetic tracking system by the processing facility;
calculating, using a processor tracking data by implementing a merging process, by the tracking system state estimator, of the state data provided by the navigation system of the moving platform and the state data derived from the at least one electromagnetic tracking system; and
effecting encoders of motors in a turning device of the antenna to direct at least one antenna for tracking the moving platform.

Abstract
A method for tracking a moving platform (MP) wherein the MP uses an on-board navigation system (NS). Data provided by the navigation system on board the moving platform (MP) is merged with data obtained using a tracking system that tracks the MP from another location. A typical navigation system on board the moving platforms is an inertial navigation system (INS). State data of one or more MP is sent to a processing facility and state data of one or more electromagnetic tracking (EMT) is collected by one or more processing facility. The collected states data from the sources are processed, using the one or more processing facilities for calculating tracking data are used to direct one or more antennas for MP tracking. The state data from one or more MP'"'"'s are sent using a communications channel.
