GPS实施的是“到达时间差”（时延）的概念：利用每一颗GPS卫星的精确位置和连续发送的星上原子钟生成的导航信息获得从卫星至接收机的到达时间差-GPS implementation is the " time difference of arrival" (delay) concept: the use of each GPS satellite and the exact location of the satellite atomic clocks generated by

该MATLAB程序确定用于非精确接近飞行阶段的接收机自主完整性监测（RAIM）基线标准算法（恒速率算法）和指定的输入数据集的可用性和故障标志（故障检测）。(This MATLAB program determines availability and failure flags (fault detection) for the Receiver Autonomous Integrity Monitoring (RAIM) baseline standard algorithm (constan
