【Abstract】 The high precision calculagraph is the key equipment in the orientation precision test system of artillery scout and checkout of UAVs. It uses high precision crystal vibrator to time and applies GPS (Global Positioning System)to adjust time, thus the distant time accordance can be ensured.At the same time, the high, precision calculagragh can offer reliable orientation precision test and data contrast for UAVs. This paper presents the working principle, hardware and software of the high precixion calculagragh, and it has reference value for the similar applications.更多还原
