Global positioning receiver has correlation channels for satellites and supplementary channels for supplementary satellites

摘要

The global positioning receiver has a correlation channel (CLi) per satellite channel. Each channel has a phase and quadrature correlation channel (12) for correlation between the received signal (Sr) and two local quadrature carriers generated by a digital carrier oscillator. It has, for each satellite correlator channel (CLi), as many supplementary correlation channels (Cix) as the supplementary satellites.
