摘要
在工作中,我们经常采用GPS用户台对空中高速运动目标进跟踪测量,而普通GPS算法无法给出高动态单点定位的定位精度。运用最小二乘原理解算动态GPS用户台的定位方程,并对其进行精度评定能够得到动态单点定位精度,且简单、实用,具有很高的实际应用价值。
During operation, GPS user station is generally used to track and measure air high-speed moving-targets. The positioning accuracy of high dynamic point positioning can＇t be achieved depending only on common GPS algorithm. Based on the principle of least square method, the positioning equation of dynamic GPS user station is solved. After the accuracy assessment, dynamic point positioning accuracy is obtained. The simple and practical method has a bright prospect of application.
