摘　　要：笔者将TBC和COSA_GPS两种数据处理软件分别运用在工程前期的数据处理中,并通过充分的比较论证,得出两者相结合的处理方法,即TBC用于基线解算、处理,COSA_GPS用于后期平差。讨论了COSA_GPS在精度要求较高的隧洞工程中,软件的一点一方位方法建立独立坐标系的优越性。论述了这2种软件的拟合GPS高程成果在水准检核和小范围测图中的应用。Both data Processing Software of TBC and COSA_GPS GNSS are applied in the data process of the early engineering stage. Fur- thermore, the processing method by combination of two software is derived from sufficient comparison and demonstration. Namely, TBC is applied for baseline calculation and processing, COSA_GPS for adjustment at late stage. In the paper, superiority of independent coordi- nate system established by one-point one-azimuth method of the software of COSA_GPS applied in tunneling with high precision require- ment are studied. Application of the fitted GPS elevation by the two software in level verification and small-scope mapping are demonstra- ted.
