卫星全球定位系统(GPS)技术正在迅速地打入商业领域。已证实美国大陆航空公司已在其飞行于阿斯彭与丹佛之间的新型 ATR-72-210飞机上使用卫星 GPS 作导航。1993年12月16日,该飞机作了首次仅用卫星导航的商业飞行。大陆快运公司飞机使用了 FMZ-9000飞行管理系统(FMS)和 HG2021全球定位系统。大陆公司的官员们希望,使用了该系统能提高导航的灵活性和精确度,降低油料消耗,改善
Satellite Global Positioning System (GPS) technology is rapidly entering the commercial arena. It has been confirmed that Continental Airlines has used satellite GPS for navigation on its new ATR-72-210 aircraft flying between Aspen and Denver. On December 16, 1993, the aircraft made its first commercial flight using satellite navigation only. Continental Express uses the FMZ-9000 Flight Management System (FMS) and the HG2021 Global Positioning System. Chinese officials hope the system will improve navigational flexibility and precision, reduce fuel consumption and improve
