| 摘 要： | 分析GPS高频单历元时间序列中的误差特性，采用中值滤波法消去高频噪声。经计算，偶然中误差在水平方向为±4～4.5 mm,高程方向为±9 mm。通过周期性重复解算、时间序列比对及相关系数最大化发现，GPS高频单历元时间序列中包含的周期性系统误差的重复周期为86 153～86 165 s。通过对系统误差建模或差分，可消除时间序列中的系统性成分，提高GPS高频单历元数据处理的精度。

| Abstract: | This paper analyzes the error characteristics of high-rate single-epoch GPS time series and uses the median filtering method to eliminate the high rate noise. Through calculation we determine that the accidental error in the horizontal direction is ±4.0-4.5 mm and in the elevation direction it is ±9 mm. By periodically repeating solutions, comparing the time series, and maximizing the correlation coefficient, the periodic system error is discovered in the high-rate single-epoch GPS time series. The repetition period is from 86 153 to 86 165 seconds. Through modeling or differencing the system errors, the system components can be eliminated from the time series, thus improving the data processing accuracy of high-rate single-epoch GPS. |
