摘　　要：研究了基于精密单点定位原理的GPS载波相位时间传递方法的数学模型和数据处理方法,设计了相应的程序流程,并基于Visual C++和Fortran混合编程的方式编写了相应的计算程序GPSCPTT V1.0。采用实际观测数据进行实验验证,结果表明,软件可以实现高精度的时间传递。The mathematical model and the data processing algorithm of GPS carrier phase time transfer based on Precise Point Positioning （PPP） are discussed in the paper. The program flow GPS car- rier phase time transfer is designed. The application software is developed using Visual C ＋ ＋ and FOR- TRAN, which is named as GPSCPTT V1.0. Large amount of raw observations are used to validate the software, which shows that it could get a quite good performance in time transfer.
