Satellite observation quality evaluation method, receiver and computer readable storage medium

The embodiment of the invention relates to the field of navigation and positioning, and discloses a satellite observation quality evaluation method, a receiver and a computer readable storage medium. The satellite observation quality evaluation method comprises the following steps: determining the actual pseudo-range of each visible satellite corresponding to the receiver at the current moment; calculating a predicted pseudo-range of each visible satellite; determining a pseudo-range residual error corresponding to each visible satellite according to the actual pseudo-range and the predicted pseudo-range; and according to the variance of the pseudo-range residual error corresponding to each visible satellite, determining the observation quality of each visible satellite, so that the accuracy and efficiency of a positioning result can be improved. 本发明实施例涉及导航定位领域，公开了一种卫星观测质量的评估方法、接收机和计算机可读存储介质。上述卫星观测质量的评估方法包括：确定当前时刻所述接收机对应的各可见卫星的实际伪距；计算所述各可见卫星的预测伪距；根据所述实际伪距和所述预测伪距，确定所述各可见卫星对应的伪距残差；根据所述各可见卫星对应的伪距残差的方差，确定所述各可见卫星的
