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.

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.

When the satellite era commenced more than a quarter of a century ago, one could hardly foresee the world wide revolution it heralded in the development of aids to navigation for merchant shipping. However, early investigations into the possible application of satellites to maritime needs led to an understanding of the powerful potential of satellite techniques for navigation. It became clear that if the international maritime community was really interested in a global all-weather, high-precision and commercially viable navigation system; such a system could only be satellite-based. This is evident from the situation that has recently arisen in IMO, where after exhaustive discussion on the mandatory carriage of electronic position-fixing equipment on ships in designated areas, the organization could not express a preference for any particular aid, until it was decided that efforts should be made to develop a global satellite navigation system capable of meeting a new standard of navigational accuracy. Moreover, in preparing the navigational accuracy standard, account was taken of experience gained with existing satellite navigation systems.

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.
