摘要
在1090ES广播式自动相关监视(ADS-B)系统中,为了对飞机的位置消息进行有效编码,经度和纬度采用简洁位置报告(CPR)的形式。介绍了CPR编解码算法的基本原理,详细描述了1090ES ADS-B系统中经度和纬度消息的CPR编解码方法,给出了全球位置和本地位置的编解码算法和实现步骤。
For the purpose of increasing the transmission efficiency, ADS-B position message (latitude and longitude of the aircraft)uses compact position reporting (CPR) format in 1090ES extended squirter Automatic Dependent Surveillance-Broadcast (ADS-B)system. The basic principle of the CPR algorithm is introduced. The CPR algorithms, including CPR encoding and decoding are described. Globally unambiguous airborne or surface position decoding, as well as locally unambiguous airborne or surface position decoding is also given.
