引言伴随着空中交通流量的迅速增长,以及对空管监视能力要求的不断提高,ADS-B技术应运而生。ADS-B的基本工作原理是:航空器依靠星基GNSS来确定航空器的精确定位信息,结合其它一些信息(如速度、高度及飞行意图数据),通过适当的数据链(S模式 Introduction With the rapid growth of air traffic and the increasing demand for air traffic control capabilities, ADS-B technology has emerged. The basic working principle of ADS-B is that the aircraft relies on satellite-based GNSS to determine the precise positioning information of an aircraft and, in combination with other information such as speed, altitude and flight intent data, through appropriate data links (S-mode
