摘 要：The new generation of global navigation satellite systems （GNSSs） introduce a third （or more） carrier, which benefit ambiguity resolution （AR）. TCAR （Three-Carrier Ambiguity Resolution） and CIR （Cascaded Integer Resolution） are the typical three-carrier ambiguity resolution methods, which are biased by the residual ionospheric delay. Based on the COMPASS three-carrier observables, this contribution investigate the TCAR/CIR methods, and accommodated them to the middle and long baseline by introducing some modifications. The modified TCAR/CIR methods contributes to the second and third steps of the old methods, which reduce the error in the second step slightly from 0.547 to 0.478, and that in the third step sharply form 17.913 to 5.062.
