摘　　要：以三频模糊度解算TCAR算法为基础,利用北斗三频实测数据,对比分析了基于TCAR算法改进后的电离层改正法和无几何无电离层组合法解算北斗三频长基线模糊度的效果。结果表明,两种方法均能提高长基线模糊度固定的准确性,且经一定历元数据平滑后均可实现长基线模糊度的快速解算,从而有利于实现长距离北斗三频精密快速导航定位。On the bisis of the three carrier ambiguity resolution（TCAR） algorithm, the two improved methods, ionospheric delay correction method and the method of geometry-free and ionosphere-free combination, were compared and analyzed with the Beidou/Compass triple-frequency surveying data. The experiment results show that both methods can improve the accuracy of long-baseline ambiguity resolution, and a rapid long-baseline ambiguity resolution after data smoothing with some epochs can be realized. The two methods can be useful for achieving the long- baseline precise rapid navigation and position with Beidou/Compass triple-frequency.
