Analysis of Beidou Triple-frequency Ambiguity Resolution

YAN Yue;  
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.
