推导了EGNOS系统不同频率情况下的完备性算法。针对GPS和GPS/Galileo组合导航的情况,模拟计算了EGNOS增强系统能为多频用户提供的完备性能。分析结果表明,EGNOS能够使GPS/Galileo系统的双频用户满足Cat-Ⅰ飞行阶段的完备性要求。
The algorithm of integrity with different frequencies of the EGNOS system is deduced. The regional integrity of EGNOS system is simulated under GPS and GPS/Galileo systems with different frequencies. The results show that the EGNOS can provide Cat- I integrity requirement in case of GPS/GALILEO systems with double-frequency.
