| Abstract: | 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 |
