Design and Implementation of GPS L2C Signal Tracking Algorithm

Abstract:

The study of GPS L2C signal tracking algorithm aims to realize signal tracking in poor environment. The main topic includes L2C signal tracking principle and the performance of real signal tracking. The structure and applied background of the signal is stated in the introduction at first. The characteristic of time division multiplexing of CM code and CL code makes this tracking method utilize half of received energy inevitably. Then, as compositions of L2C signal tracking algorithm, the data demodulation, the code tracking and the carrier tracking module are showed their details in the paper, including the structure of the DLL tracking loop, the Costas carrier tracking loop and some necessary computational principles. Finally, compare happens on real excellent and poor signal-to-noise ratio environments by setting suitable parameters including the sampling frequency, the center frequency and the pseudo code rate to prove the effectiveness of tracking algorithm.
