Abstract
A GPS receiver includes an RF section and a digital section, the digital section including a correlator circuit for performing correlation with respect to a plurality of satellite channels. The GPS receiver is operated by cycling power to the RF section on and off according to a determined duty cycle having an ON portion and an OFF portion. During the ON portion, navigation related data received from the plurality of satellite channels is sampled by higher level software. Continuity of function may be achieved by resetting a state of at least a portion of the correlator circuit in correspondence to a transition from the OFF portion to the ON portion.
