Abstract:

以亚洲地区46个IGS站2008-2011年实测的高精度天顶对流层延迟(ZTD)数据为参考值,通过对2008-2010年EGNOS模型计算ZTD的日均偏差进行频谱分析,建立了亚洲地区EGNOS模型的单站修正模型(SSIEGNOS),对EGNOS和SSIEGNOS模型在亚洲地区的精度和适用情况进行了评估,结果表明(1)EGNOS模型偏差和RMS在时间分布上呈现明显的季节变化规律,而SSIEGNOS模型偏差和RMS变化较小且平稳;(2)在空间分布上,两种模型的偏差随着经纬度和高程的变化均无明显规律,但随着高程或者纬度的增加RMS总体上都有递减的趋势;(3)SSIEGNOS模型预测ZTD的精度相对于EGNOS模型有明显提高。
