RECEIVER FOR GLOBAL NAVIGATION SATELLITE SYSTEM

摘要

A GPS receiver is provided to detect signals at a high signal amplification rate accurately, reduce the acquisition time delay and guarantee the continuity of tracking. A processing unit performs the predetermined processing for a received GPS signal to generate a correlation target signal. A correlation unit produces a correlation value for a code used in a GNSS system with respect to the I and Q component of the correlation target signal. A code tracking unit performs the code tracking based on the calculated correlation value.
