微型无人驾驶飞机气象探空系统

A ROBOT PLANE METEOROLGICAL SOUND SYSTEM

微型无人驾驶飞机气象探空系统由微型无人驾驶飞机、数字化探空仪和地面接收控制处理系统组成。微型无人驾驶飞机采用ＧＰＳ导航，具有自动导航、自动驾驶功能，它能在机载自动控制系统控制下完成预定航线的飞行，并实时地将飞机的飞行轨迹和探测数据传送到地面。地面接收控制处理系统显示飞机所在位置的经纬度、高度和探测资料，并可发出控制指令。数字化探空仪采集温、压、湿资料。利用ＧＰＳ信息进行测风处理，获得风向风速。

A meteorological sounding system, consisting of a miniature robot plane , an aircraft borne digital sonde unit, and a ground based subsystem. The flight of mini aircraft is controlled by an onboard auto control system according to a pre designed navigation line under the guidance of Global Position System (GPS) data. Flight tracking and air sounding data can be transmitted in real time to ground receiver. The ground based subsystem would process the received data with a computer and display the geographic position and height of the aircraft and meteorological parameters observed. The ground based subsystem can also send command to the aircraft to manipulate its flight in a remote control manner. The sonde unit measures temperature, pressure and humidity. Wind speed and direction are derived from GPS data.
