Abstract
A method and apparatus for operating a two channel digital global positioning system receiver for receiving coded satellite signals from each of a plurality of satellites, where the signals exhibit Doppler shifts. The method comprises the steps of continuously tracking of a particular one of the satellites for receiving information included in the coded satellite signals by one channel of the receiver, and sequentially tracking of each of the plurality of satellites, except the one particular satellite, by the other channel of the receiver for receiving information included in the coded satellite signals.
