目前,国内许多机场都安装了VOR/DME 设备,航空器加装了 GPS设备,为航空器导航提供了方便条件。但从当前的使用情况看,还没有充分发挥其效能。如果说航管雷达可供飞行管制人员使用,那么,VOR/DME 和 GPS 既可供飞行人员使用,也可供飞行管制人员和飞行签派人员间接使用。进而言之,如果能解决航空器上 VOR/DME 接收机、GPS 及高度表信息应答反馈问题,它的作用将不亚于二次雷达。 Currently, many domestic airports have installed VOR / DME equipment, aircraft equipped with GPS equipment, navigation for aircraft provides a convenient condition. However, from the current use of the situation, have not fully demonstrated their effectiveness. If air traffic radar is available to flight controllers, VOR / DME and GPS are available to pilots as well as for indirect use by flight controllers and flight dispatchers. Furthermore, if it can solve the feedback problem of VOR / DME receiver, GPS and altimeter information on aircraft, its role will be as good as that of secondary radar.
