Patent ID: 8665147

Claim:
A global positioning system (GPS) receiver comprising: a first antenna and a second antenna, the first and second antennas configured to receive a radio frequency (RF) signal carrying a GPS source signal including a C/A code; a first radio circuit coupled with the first antenna and configured to down-convert the RF signal to a first signal; a second radio circuit coupled with the second antenna and configured to down-convert the RF signal to a second signal an acquisition block adapted to receive the first and second signals, the acquisition block configured to generate a local code and a coarse-aligned C/A code in response to the C/A code and the local code, the coarse-aligned C/A code including a coarse phase and a coarse carrier frequency; and a signal processing section adapted to receive the first and second signals, wherein the signal processing section is configured to; track a C/A code phase using the coarse code phase; and track a carrier frequency of the RF signal using the coarse carrier frequency.
