摘　　要：本文通过前观车和自行火炮均采用 GPS定位时 ,对所测目标的位置误差及几何诸元误差的分析 ,给出了几何诸元误差与 GPS定位精度、射距离、观炮夹角等参数之间的关系。提出了减小几何诸元误差的措施 ,为进一步分析火炮的射击精度提供了依据。This paper presents an analysis for the geometrical firing data (GFD) error in self-propelled gun systems positioned by GPS. In general the observable vehicle and the gun system are positioned by GPS. As the measured target errors and the geometrical data errors are given, the functional relationship between GFD and factors such as GPS positioning accuracy, range and angle for observation and gun are determined. Some steps to lessen the errors of GFD are shown. The work suggests a direction in improving firing accuracy.
