From page 154...
... GPS receivers normally track more than one signal at a time using multiple channels, but also can track multiple signals using either a single channel sequenced between satellite signals or a multiplexing channel. Once the digital signal processor is successfully tracking a set of GPS signals, the ranging data it extracts is passed to the microprocessor, where t9 A Kalman Filter incorporates both observations and mathematical models of the system dynamics to produce an optimal estimate of the current state of a system.
