摘 要: 全球定位系统(global positioning system, GPS)多系统并存、多技术融合阶段的确立可为用户提供大量的可视卫星,使GPS满足实际应用中更高精度、更高可靠性的要求。接收机自主完备监测(receiver autonomous integrity monitoring,RAIM)技术以粗差探测与剔除技术为核心,优化全球导航卫星系统(global navigation satellite system, GNSS)卫星星座,保证导航解满足实际应用的特殊要求。这里建立GPS/GLONASS组合系统模拟星座,构建伪距绝对定位因素,推导了基于抗差的最小二乘法,并通过抗差最小二乘及抗差卡尔曼滤波方法验证RAIM算法,优化组合星座系统,并指出组合星座系统优化的关键因素。
关 键 词: 大地测量学与测量工程;GPS/GLONASS组合系统;接收机自主完备监测;粗差探测与剔除

Abstract: As the phase of multi-system co-existence and multi-technology integration in the global positioning system can provide a large amount of visible satellites to users, how to ensure the completeness of the satellite constellation, and to achieve higher positioning accuracy and reliability has become a research topic of concern. Receiver autonomous integrity monitoring (RAIM) techniques take the fault detection and exclusion techniques as the core, optimize global navigation satellite system (GNSS) satellite constellation and ensure the navigation solution meet the requirements of the practical application. This paper established GPS/GLONASS combination system simulated constellation, verified the feasibility of RAIM algorithm by simulation data, and pointed out the key factors of different combination of constellation.
Key words: geodesy and survey engineering; GPS/GLONASS combination system; receiver autonomous integrity monitoring; fault detection and exclusion
