The invention discloses a multi-data-source flight takeoff time correction method, which receives takeoff event messages of different data sources in real time, and is characterized in that the processing process of each piece of message data comprises the following steps of: verifying the validity of the message data; judging whether the final flight take-off time is determined or not; if the final take-off time of the flight is not determined, determining the message take-off time as the first take-off time, and verifying the take-off time by using the ADS-B data; and if the final take-off time of the flight is determined and earlier than the take-off time of the message, ending the judgment of the message, otherwise, verifying the final take-off time of the flight and the take-off timeof the message by utilizing the ADS-B data, and deciding whether to correct the final take-off time or not. According to the method, the flight takeoff time is verified by using the ADS-B data; the method comprises single take-off time verification and two take-off time verification, does not only depend on historical data statistical analysis and experience to formulate a selection or filtering rule, is beneficial to overcoming the defect that a previous rule type method depends on historical data and experience, and is beneficial to improving the accuracy of the take-off time.

    本发明公开了一种多数据源航班起飞时间校正方法,实时接收不同数据源起飞事件报文,其特征在于,对每条报文数据的处理过程包括下述步骤:校验报文数据有效性;判断航班最终起飞时间是否确定;若航班最终起飞时间未确定,则将报文起飞时间确定为第一个起飞时间,并利用ADS‑B数据对该起飞时间进行校验;若航班最终起飞时间已确定,且早于本条报文起飞时间,则结束本条报文判断,否则利用ADS‑B数据对航班最终起飞时间和报文起飞时间进行校验,并决定是否校正最终起飞时间。本发明的方法利用ADS‑B数据对航班起飞时间进行校验,包括对单个起飞时间校验和对两个起飞时间校验,不仅仅依赖通过历史数据统计分析和经验制定选择或过滤规则,有助于克服此前规则式方法依赖于历史数据和经验,有助于提高起飞时间准确性。
