长度

The Babylonians did not use the hour, but did use a double-hour lasting 120 modern minutes, a time-degree lasting four modern minutes, and a barleycorn lasting 313 modern seconds (the helek of the modern Hebrew calendar).

In this dissertation, GPS baseline solution precision is analyzed since the following aspects: 1, Different length baselines are processed and analyzed by single frequency model and ionosphere free model. 2, Basing on current single point positioning precision, certain coordinate error is added into fixed points to study the result. 3, Baseline is processed and analyzed with different observation vectors and their lineal combination models. 4, 24 hours observation was divide up to process baseline.

本文从以下几个角度研究了影响GPS基线解算精度的因素：1、采用单频和消电离层模式对不同长度的基线分别解算，对处理结果进行分析。2、根据目前单点定位精度给起始点加上适当的坐标偏差，研究起始点坐标偏差对基线处理结果的影响。3、选用不同的观测值及其线性组合，对基线解算结果进行研究。4、对24小时观测的数据分时段处理，分析观测时间段对基线处理结果的影响。
