针对地面用户接收机的性能易受各种复杂环境影响的问题，研究了在遮挡、多径等复杂环境下，提高和保持定位精度及稳定性的定位算法。基于RAIM思想，对量测信息进行故障诊断和处理，给出了一种高性能、低复杂度的EKF算法。仿真和试验表明，该算法不但提高了定位的精度，而且具有较强的鲁棒性和较强的工程实用性。

The performance of the receiver for terrestrial users vulnerable to a variety of complex issues affecting the environment stud-ied occlusion, multipath and other complex environments, improve and maintain the accuracy and stability of the positioning algo-rithms.RAIM-based thinking on the measurement information for fault diagnosis and treatment, gives a high-performance, low-complexity EKF algorithm.Simulations and experiments show that the algorithm not only improves the positioning accuracy, but also has strong robustness, with strong engineering practicality.
