无人机远程检测中的高精度计时器

High Precision Time Counter for Remote Testing of Unmanned Aircraft

高精度计时器是无人机定位精度检测系统中的关键设备。它利用GPS进行计时校准,通过高精度晶体振荡器进行计时,保证了远距离的时间统一,为无人机定位精度的检测和数据对比提供可靠的保证。文章对高精度计时器的工作原理、硬件、软件等进行了说明,对同类应用具有一定参考价值。

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.
