According to the method of assessing troposphere estimation precision in kinematic PGS water vapor inversion.The paper proposed a new method to assess troposphere estimation precision through tropospheric delay closing conditions and tropospheric delay connecting conditions.By analyzing PBO observation network's 12 CORS stations and 6IGS stations observation data to assess kinematic troposphere estimation precision through inner closed precision and external coincidence precision.Inner closed precision method in data processing,calculating the relative tropospheric delay results every 15 sby IGS ephemeris.Inner closed precision can meet the basic requirement weather forecast in GPS water vapor inversion.External coincidence precision method in data processing,calculating the tropospheric zenith delay by IGS ephemeris and IGU ephemeris,then compared with static reference result,found the results are highly consistent.This research has an important reference value for the precision of kinematic atmospheric delay solution in kinematic GPS water vapor inversion
