摘要
航管系统采用球心方位投影的方式把经纬度和高度组成的地理坐标系投影到平面直角坐标系中,该系统中的空域有限制区、禁区和危险区和责任区四种类型,不同类型的空域告警预警参数不同。航管系统中空域有固定空域和移动空域之分,同时也都有激活和非激活两种状态。激活状态下,系统对飞行器的当前位置和运动趋势进行实时监视,计算出该飞行器对空域的侵入趋势以及侵入状态。如果已经发生侵入或有侵入趋势,系统中该飞行器的标牌会发生闪烁,并在标牌和屏幕左上角显示告警或者预警信息。
Carrier Air Traffic Control System uses gnomonic azimuthal projection to transform Geographic coordinates including latitude and longitude and height into Cartesian coordinates. The system has four types of airspace restricted zone, restricted and danger areas and areas of responsibility. Different types of airspace have different warning and predict warning parameters. The system has fixed airspace and moved airspace. There are two states of airspace, active and inactive state. In the active state, the system calculates the trend of airspace intrusion and invasion status according to the real-time monitoring on the current position and movement trends of aircraft. If invasive or intrusive trend has occurred, the aircraft label will flicker and display alarm or warning information in the upper left corner of the screen.
