摘要
在1090ES广播式自动相关监视(ADS-B)模式下,针对飞机的位置信息中涉及经纬度编解码算法的内容进行了简要介绍,主要涉及经纬度编码、本地解码、全球解码算法的具体实现步骤。通过检飞验证,研究结果表明,简洁位置报告(Compact Position Reporting,CPR)编解码具有很高的有效性和准确性,能有效提高成功接收报文的概率。
Under the 1090ES Automatic Dependent Surverillance-Broadcast(ADS-B)mode,the encoding/decoding algorithm of latitude and longitude involved in the airplane's position information is briefly introduced,including the specific implementation steps of latitude and longitude encoding,local decoding and global decoding algorithms.Through flight inspection verification,the results show that the encoding and decoding of Compact Position Reporting(CPR)has high validity and accuracy,effectively improving the probability of successfully receiving the ADS-B message.
