随着研制和生产GPS用户设备的厂家日益增多,全球定位系统(GPS)的应用范围正在扩大。属于航空领域的应用有:空中交通警报和防撞系统(TCAS),自动着陆系统,直升机悬停和风的切变检测系统。 与TCAS相关的应用 GPS系统能够提供三维的位置数据和测定加速度。所以使用GPS的TCAS也会有垂直速度信息,从而能够更好地预测将在邻 With the increasing number of manufacturers developing and producing GPS user equipment, the range of applications for the Global Positioning System (GPS) is expanding. Applications belonging to the aeronautics field include: air traffic alert and collision avoidance system (TCAS), automatic landing system, helicopter hover and wind shear detection system. Applications related to TCAS GPS systems provide three-dimensional position data and measured acceleration. So GPS using TCAS also has vertical velocity information, which can better predict the adjacent
