The influence elements of TCAR success rate are analyzed and several improved schemes are proposed.From the combina-tion modes,the fix mode from extra-wide lane to wide lane and to narrow lane is abandoned and based on the analysis of influence ele-ments of TCAR,the selection rules of the combinations of TCAR are discussed,several recommended combinations are picked out for short baselines and middle-long baselines respectively.The smoothing window technique is introduced to smooth the error caused by observation noise and weaken the influence of observation noise,which increases the success rate of ambiguity of TCAR.Aiming at the problem of ionosphere error for middle-long baselines,a method uses the two combinations of observations to estimate ionosphere error and correct the fixed ionosphere error in the next step,which increases the its success rate.
