The research of GLONASS signal and base-band processing techniques
He Jiang, Chengjun Guo · 2014
Global Navigation Satellite System (GLONASS) supervised by Russia has attracted many researchers as its specialness. The paper firstly analyzes the signal system and navigation message of GLONASS. It uses BPSK modulation and frequency division multiple access (FDMA) technology and transmit L1 or L2_carrier signals. Secondly, the base band processing strategy is analyzed and designed. Then quick capture algorithm of frequency based on FFT is improved, track method and Synchronization strategies are designed. The simulation will certify the correction of signal and method. It will have a certain theoretical significance to study of GLONSS applications and software receiver today.
