Power saving method adaptable in GNSS device

摘要

A method and system for navigation are provided to locate a GNSS device. The GNSS device comprises a RF front end receiving satellite signals of a plurality of satellites, and a GNSS device comprising a plurality of correlation channels each performing a correlation process to generate a correlation result from satellite signals corresponding to a satellite, a memory device for storage of the correlation results, and a processor performing acquisition and tracking based on the correlation results.
