摘要
卫星导航为飞机导航提供了高精度和灵活性,它将开创以卫星为基础的空中交通管理的新时代。新的交通管理系统将包括飞行计划,包括用自动相关监视(ADS)监控飞机在航路导航、防撞、着陆中的位置以及管理飞机在机场表面的运动,允许飞机离开固定的航路直接飞向目标,以及在不需要昂贵地面设备的机场作精密进近,从而节省大量时间和金钱。
Collins Commercial Avionics has launched the A VSAT line of satellite-based precision-navigation systems . In a satellite-based ATM system , the integrity of GPS data is critical to safety . The A VSAT is based on the premise that GPS is the source of position information , not just another sensor . As a result, the A VSAT design houses all flight-critical functions, such as position determination and approach computation, within the GPS receiver to ensure integrity . The AVSAT family is based on a purpose-designed sensor, the Commercial Avionics GPS Engine ( CAGE ), which consists of a single circuit-board with three five-channel GPS-receiver microchips .
