本发明公开一种针对编队表演的飞机GPS数据异常检测和异常确认的方法,涉及无人机数据处理技术领域。当飞机收到GPS状态后,对飞机的星数、定位模式、差分龄期进行判断筛选;针对舞步表演,对GPS状态进行判断,若GPS定位模式不满足RTK固定状态,或GPS差分龄期大于一起飞阈值,则不允许起飞;在编队表演飞行过程中,若飞机搜星数量小于一数量,且根据GPS状态结构中的时间戳判断,超过给定的飞行阈值,则反馈飞机。本发明实现了针对编队飞行表演飞机GPS状态确认的功能,降低了因为GPS状态变化及GPS受干扰时数据变化对飞行控制的干扰,解决了GPS异常判断不准确对编队飞行表演的影响。

    The invention discloses an aircraft GPS data anomaly detection and anomaly confirmation method for formation performance and relates to the technical field of unmanned aerial vehicle data processing. After the aircraft receives a GPS state, the star number, the positioning mode and the differential age of the aircraft are judged and screened; for dance step performance, the GPS state is judged, and if the GPS positioning mode does not meet the RTK fixed state or the GPS differential age is larger than a take-off threshold value, take-off is not allowed; and in the formation performance flight process, if the number of the satellite searched by the aircraft is smaller than one and the aircraft is judged to exceed a given flight threshold according to the timestamp in the GPS state structure, the information is fed back to the aircraft. According to the method, the function of confirming the GPS state of the formation flight performance airplane is realized, the interference of data change on flight control due to GPS state change and GPS interference is reduced, and the influence of inaccurate GPS abnormality judgment on formation flight performance is solved.
