INTER-CHANNEL BIAS CALIBRATION FOR NAVIGATION SATELLITE SYSTEMS

摘要

Dynamic inter-channel bias calibration of a navigational receiver is provided. A reference signal is propagated through front end circuitry of the receiver. A delay caused by the propagation of the reference signal through the front end circuitry is measured. The inter-channel bias of the navigational receiver is reduced using the measured delay associated with the front end circuitry of the receiver.
