摘要
针对基于卫星导航的着舰系统移动参考站载波相位观测监测的需求,提出了载波相位多参考站一致性监测方法。基于舰船位置、姿态和多参考站天线相位中心在舰船坐标系的位置,将多站接收机载波相位观测、伪码观测虚拟到理想着舰点;利用虚拟载波相位和伪距的变化值作为检测统计量,构建伪码和载波B值,参考门限进行比较,判决是否有故障产生。仿真表明,论文提出的一致性检测算法,可以有效检测载波周跳、多径造成的伪距突变,能够单历元检测发现故障。
As the requirement multiple reference consistency of landing system on aircraft carrier based on carrier phase,the paper proposes a method to solve the problem of carrier phase B-value check on moving reference station.Carrier phase and pseudo range are comprehended to the ideal landing point of ship and generating the visual observations based on ship position,attitude and receiver antennas position in the ship coordinate system.The change values of the visual carrier phase and pseudo range of multiple references are used to generate the B-value to judge the fault.Through the experiment and research,the algorithm is valid to check carrier phase slips and pseudo range changes due to multipath in one period.
