GPS天线相位转绕误差及其对PPP的精度影响分析

内容简介：对于GPS精密单点定位,天线相位转绕误差无法通过星间求差法消除或减弱,因此必须通过适当的模型加以改正,详细分析了该误差的特性及其改正方法,并采用自编软件,通过计算实例,分析其对GPS精密单点定位的精度影响。

Abstract：Phase windup in GPS precise point positioning can not be eliminate or mitigate easily,so it is important to deal them with accurate correction models,or set residuals of them as unknown parameters.The phase windup error and it＇s correction models are discussed detailed.Numerical result shows the accuracy of PPP using the correction model.
