WebGPS C/A Signal (The GPS Coarse / Acquisition (C/A) code is a 1023 chip Pseudo-Random Noise (PRN) sequence transmitted on the GPS L1 band with a carrier frequency of 1575.42 MHz. The C/A code is modulated on to the carrier by Binary Phase Shift Keying (BPSK). As all GPS satellites are using the same carrier-frequency, a Code Division WebChapter 2 examines the mathematical modeling or formulation of GPS tracking signal structure, coupled with the GPS modernization, and the key types of the GPS …
