The invention discloses a time synchronization method for an air forwarding type ADS-B message, and the method comprises the steps: firstly decoding the ADS-B message after a receiver of the ADS-B on a forwarding aircraft receives the ADS-B message, and determining that the ADS-B message is the ADS-B message of a remote aircraft which needs to be forwarded if the ADS-B message does not have a timestamp; storing the timestamp of the moment when the ADS-B message of the remote aircraft is marked to be received on the ADS-B message band of the remote aircraft into a transmitting cache region; storing the real-time position of the forwarding aircraft in a transmitting buffer area through an independent ADS-B message, the priority of the ADS-B message of a remote aircraft with a timestamp in the transmitting buffer area being the same as that of the ADS-B message of the aircraft, and broadcasting through the same transmitting channel; and the ground station analyzing the position data of the remote aircraft through the real-time position of the forwarding aircraft and the timestamp of the ADSB message of the remote aircraft received by the forwarding aircraft.

    本发明公开了一种空中转发式ADS‑B报文的时间同步方法,当转发飞行器上ADS‑B的接收机接收到ADS‑B报文后,先对ADS‑B报文进行解码,若ADS‑B报文中没有带时间戳,则该ADS‑B报文为需要转发的遥远飞机的ADS‑B报文,将遥远飞机的ADS‑B报文带上标记接收到遥远飞机的ADS‑B报文的时刻的时间戳存入发射缓存区;转发飞行器本身的实时位置通过独立的ADS‑B报文存入发射缓存区,发射缓冲区中的带时间戳的遥远飞机的ADS‑B报文和本机的ADS‑B报文优先级相同,采用相同的发射通道分时广播;地面站通过转发飞行器的实时位置和转发飞行器收到遥远飞机的ADS‑B报文的时间戳分析出遥远飞机的位置数据。
