Embodiment

[0041] The technical terms involved in the present invention include:

[0042] The full name of ADS-B is Automatic Dependent Surveillance-Broadcast, which is Automatic Dependent Surveillance-Broadcast, which means that it can automatically obtain parameters from related airborne equipment and broadcast the aircraft's position, altitude, Speed, heading, identification number and other information for the controller to monitor the status of the aircraft. ADS-B information data mainly includes four-dimensional information of the aircraft: longitude, latitude, altitude and time, and also contains other information related to the flight, such as flight identification number, flight heading, flight speed, etc. Because of this, a lot of real-time information about flights can be known from ADS-B data: according to the flight identification number, the flight number, origin and destination of the flight can be known; at the same time, the status of the flight can be judged based on ot...

Abstract

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.

Description

technical field [0001] The invention relates to a multi-data source flight departure time correction method, which belongs to the technical field of civil aviation information. Background technique [0002] Accurate and timely flight departure time is very important to industry management, airline companies and passengers. For industry management, it helps to improve the efficiency of aviation control and the utilization rate of air routes and airspace; Be able to make travel arrangements calmly and reduce long waits caused by flight delays. [0003] At present, the civil aviation industry has a variety of data sources, but due to various reasons, none of the data sources can guarantee absolute authenticity and integrity, and there are various degrees of errors, errors and missing data. For this reason, airline companies usually choose to obtain data from multiple data sources. For example, the data sources of departure time include airport data sources, airline data sourc...
