Abstract
Official abstract text for this publication.
Systems and methods for a scanning correlator for global navigation satellite system signal tracking are provided. In one embodiment, a method for Global Navigation Satellite System (GNSS) receiver tracking comprises: receiving a GNSS navigation signal; generating a local Pseudo Random Noise (PRN) sequence; sampling the GNSS navigation signal over a plurality of integration periods to produce a plurality of scanning values, wherein each scanning value has a respective time offset such that at least one first time offset is not equal to at least one second time offset; estimating at least two points of an autocorrelation function for the GNSS navigation signal based on the plurality of scanning values; and calculating an alignment between the GNSS signal and the local PRN sequence based on the autocorrelation function estimate.
First claim
Opening claim text (preview).
What is claimed is: 1. A Global Navigation Satellite System (GNSS) receiver, the receiver comprising: a front end configured to receive GNSS signals; a code and carrier remover coupled to the front end; a carrier numerically controlled oscillator coupled to the code and carrier remover and generating a first oscillating signal, a code numerically controlled oscillator coupled to the code and carrier remover and generating a second oscillating signal, wherein the code and c…
