METHOD FOR VECTOR PHASE TRACKING A PLURALITY OF GLOBAL POSITIONING SATELLITE CARRIER SIGNALS

摘要

A method for vector phase tracking a plurality of global positioning satellite carrier signals is disclosed, in which for a tracked satellite a discriminator (25) is generating phase tracking error signals at different frequencies associated with the various carrier signals of the tracked satellite and in which a multi-frequency estimation of the disturbances is performed based the phase tracking error signal supplied by the discriminator unit (28). In the method the ionospheric error is taken into account for determining output phase error signals.
