求翻译：Following the development of radar in World War II, it was deployed as a landing aid for civil aviation in the form of Ground-controlled approach (GCA) systems, joined in 1948 by distance measuring equipment (DME), and in the 1950s by airport surveillance radar as an aid to air traffic control. VHF omnidirectional range (VOR) stations became the predominate means of route navigation during the 1960s, superseding the low frequency radio ranges and the Non-directional beacon (NDB). The ground based VOR stations were often co-located with DME transmitters and then labeled as VOR-DME stations on navigation charts. VORTAC stations, which combined VOR and TACAN features (military TACtical Air Navigation) 是什么意思？

雷达在二次世界大战中的发展，它是作为民用航空的着陆援助地面-控制方法 （好市民奖） 系统，加入了在 1948 年的距离测量设备 (DME) 的形式和上世纪 50 年代由机场雷达作为部署援助，空中交通管制。甚高频全方位范围 （VOR） 站成为路线导航在六十年代，取代低频无线电范围和非定向信标 （国家发展银行） 的主导手段。地面义和站是经常合用二甲醚发报，然后标记为 VOR DME 电台导航图上。VORTAC 站，联合甚高频全向信标和塔康信功能 （军事战术空中导航）
