摘　　要：以北斗系统为背景,介绍了三频组合观测值的特点,分析了双差三频组合观测值的误差影响因素。简单说明采用TCAR方法进行超宽巷和宽巷模糊度固定的方法,论证了采用超宽巷或宽巷组合来求解电离层延迟一阶改正的不可行性。Taking BDS as background, we introduced fundamental equations of three Beidou signals and analyzed the influence of errors in double-differenced combination measurements at first. And then, we briefly described the three carrier ambiguity resolution(TCAR), using which to fix the ambiguity of extra-wide-lane and widelande combination, whose characteristics were given. Finally, we put forward the observational equation for double-differenced narrow-line carrier combination, discussed the methods of basic carrier ambiguity resolution, and summarized the application of TCAR in Beidou triple-frequency ambiguity resolution.
