摘　　要：靶场测量设备精度评估对真值的要求越来越高。高精度的GPS定位技术已成为靶场外测设备动态精度鉴定的重要手段。在采用多基站测量方案的精度校飞实验中,多基站差分定位结果直接关系对被检验设备精度的判定质量,本文提出了一种多基线测量数据加权处理方法,给出了多基线定位的残差误差分析公式。动态飞行实验数据分析结果表明多基线定位精度高、可靠,随机误差服从均值为0的正态分布。True value accuracy becomes more important in accuracy evaluation of range instrumentation.High precision GPS positioning technology is a significant measurement for dynamic testification as a mean of obtaining true value.In an instrumentation accuracy calibration test by utilizing a multi-base measurement scheme,the multi-base positioning results can affect the quality of evaluating the instrumentation tested.This paper proposes a weighing processing method of multi-baseline kinetic measurement data and presents a formula of analyzing multi-baseline positioning residual error.The result of airborne target measurement data processing shows that multi-baseline positioning precision is high and reliable,and random errors comply with a normal distribution which mean is zero.
