The invention discloses a method for initializing a 4D air-ground cooperative operation. Because of the need of initializing 4D operation, cooperation of key parameters such as a four-dimensional track between the air and ground is realized by using an ADS-C communication link and a CPDLC communication link fully. An airplane uses the air-ground negotiation result as the base of four-dimensional track guidance to realize automatic flight and precise control of the four-dimensional track. With the method, the stable and smooth operation of the four-dimensional track can be supported. The methodbeing easy to realized in engineering has the important practical application significance in prompting operation of the aircraft in the civilian area, improving the utilization rate of the airspace,especially the terminal region, and enhancing the flight safety.

The invention discloses a course anomaly detection and safety protection method and device, equipment and a storage medium. The method comprises the steps: when the unmanned aerial vehicle is in a flight scene, acquiring magnetic compass associated data, at least one piece of real-time dynamic RTK associated data and gyroscope data; judging whether the magnetic heading of the unmanned aerial vehicle is abnormal or not according to the magnetic compass associated data, judging whether the RTK heading of the unmanned aerial vehicle is abnormal or not according to the at least one piece of RTK associated data, and judging whether the real-time fusion heading of the unmanned aerial vehicle is abnormal or not according to the gyroscope data and the magnetic heading; and if at least one of the magnetic heading, the RTK heading and the real-time fusion heading is determined to be abnormal, executing at least one safety protection measure. By using the technical scheme of the invention, accurate and stable course anomaly detection and safety protection of the unmanned aerial vehicle can be realized, timely and effective safety protection can be performed when the course is abnormal, and the flight safety of the unmanned aerial vehicle is improved.

The present invention relates to an unmanned aerial vehicle authentication method and device. The method includes: if the flight status information reported by the drone is received, determining whether the drone is a legal drone, and the flight status information is used to indicate that the altitude of the drone is greater than or equal to a predetermined height. Set a height threshold; when the drone is a legal drone, provide communication services for the drone; when the drone is an illegal drone, stop providing communication services for the drone . In this technical solution, the base station can determine whether the currently flying drone is a legal drone, and provide communication services for the drone when it is a legal drone, and when the drone is a legal non-unmanned drone When the drone stops providing communication services, it realizes the supervision of the drone, improves the flight safety of the drone, and is conducive to the long-term development of the drone.
