Galileo system is a new satellite navigation system. In this paper, a Galileo signal receiver based on W phase detector is presented. It can capture and track the Galileo signals. Moreover, it can also reduce location errors caused by the multipath signal when the delay is just small chip length away from the useful signal. At first, the principle of the traditional E-L phase detector and its anti-multipath performance is analyzed in this article. Finally, the forming method of the W phase detector waveform is introduced.

Simulation Results

The COMPASS/Beidou Satellite Navigation System is no-blind zone for China and limited transmission capacity. It is critical for increasing the performance of disaster warning distribution by the COMPASS/Beidou system. By further analyzing the characteristics of transmission of COMPASS/Beidou, we find the method of solving that problem and also introduce some optimizations into the algorithm. The algorithm is based on application layer FEC to achieve the warning transmission probabilities. Simulation results show that the new scheme can efficiently be used disaster warning distribution system.

Multi-constellations provide much better satellite geometrics, thus RAIM algorithms areexpected to achieve greater reliability and integrity performance. This paper mainly discusses different RAIM algorithms and gives simulations of RAIM availability and reliability of standalone GPS and integrated GPS/GLONASS, GPS/BEIDOU and GPS/GLONASS/BEIDOU constellations.The results show that multi-constellation improve RAIM availability and reliability greatly. It is no less than 99.7%for APV I. Also MDB values indicate thatinternal and external reliability of satellite navigation system can be enhanced by multi-constellation.
