ADS-BADS-B是广播式自动相关监视的英文缩写,它主要实施空对空监视,一般情况下,只需机载电子设备(GPS接收机、数据链收发机及其天线、驾驶舱冲突信息 显示器CDTI),不需要任何地面辅助设备即可完成相关功能,装备了ADS-B的飞机可通过数据链广播其自身的精确位置和其它数据(如速度、高度及飞机是否转弯、爬升或下降等)。ADS-B接收机与空管系统、其它飞机的机载ADS-B结合起来,在空地都能提供精确、实时的冲突信息。 ADS-B 是一种全 新科技,它将当今空中交通管制中的三大要素通信、导航、监视重新定义。Results: ADS-B

majority (70% or so) of Mode S-equipped aircraft do not broadcast their
position via ADS-B. ADS-B packets are type 17 and you will see lat/

that a 8MSPS rate. I used the 8MSPS rate and still got good
performance. The oversampling is used in determining if the pulse is
