Title:
A Method for Tracking a plurality of global positioning satellite signals: Multi-Carrier Vector Phase Locked Loop 
Claims:
1. A method for vector phase tracking a plurality of global positioning satellite carrier signals (4) comprising the steps of: - determining the input phase tracking error signals by a phase extraction unit (33) depending on trackable carrier signals (4) and oscillator signals associated with the trackable carrier signals (4); - transforming the input phase tracking error signals in a spatial domain by a transformation unit (28, 41, 91, 101, 111) for generating spatial difference signals; -...    »
 
Abstract:
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 i...    »
