摘　　要：用上海天文台研制的八通道GPS定时接收机PTS－1^[1]，进行了不同的测量处理方法比较，极用测量平均法和测量拟合法的结果表明，定时精度和测频精度比单点测量法提高2－3倍，达到30ns和3×10^-13/d,这种低代价的轻便接收机能获得更好的效益，对许多用户是有实用价值的。The different methods and its results of measurement-data processinghave were compared, by using the eight-channel GPS timing receiver PTS-1 [1] that developed by Shanghai Astronomical Observatory. The results adopted by the methods of measurement-averaging and measurement-fitting are showns that the precisions of timing and measuring frequency improve about 2～3 times than with the results of measurement methods of a single point, they arrive 30ns and 3×10 -13 /d respectively. The portable receiver of low cost can obtained more benefit, it is practical value for many users.
