摘要
本文中,采用多元线性逐步回归分析方法进行了接收参数——信噪比(SN)、仰角(EL)、方位角(AZM)、电离层(ION)对GPS时间比对精度(在数据跟踪持续时间15分钟内取样平均时间为10秒的时间起伏均方差)影响的一些比较分析,结果表明:信噪比这个参数在多数情况中是影响GPS时间比对精度的主要因素。
By using the regression analysis method of polybasic linear and one by one, we carried on some comparison and analysis of the effects of the receiving parameters-Signal-to-Noise Ratio (SN), Angle of Elevation (EL) , Azimuth (AZM), Ionsphere (ION) on GPS time comparison precision (RMS of the time fluctuation for the sampling average time of 10 seconds within the data tracking duration of 15 minutes) in this paper. The results show that the parameter SN is the main factor which effects GPS time comparison precision in most cases.
