Aircraft flight path jump removing method

Abstract

The invention discloses an aircraft flight path jump removing method, which comprises the following steps: constructing a cubic polynomial fitting algorithm in corresponding type and at non-fixed time intervals, and calculating predicted values corresponding to altitude, angle, ground velocity and vertical velocity and storing the predicted values; when receiving latitude and longitude values, and if the number of latitude and longitude elements in a set within a time range 1 minute before the current time is smaller than 3, not carrying out calculating and quitting; or otherwise, comparing the longitude and latitude at the current time with longitude and latitude at a previous time point and longitude and latitude at a time point before the previous time point: calculating predicted distance and actual distance, and comparing the difference between the predicted distance and the actual distance and larger one of the predicted distance and the actual distance to obtain data credibility weight; and if the data credibility weight is smaller than 1, regarding the data as credibility data and storing the data. The method can solve the problem of longitude and latitude or height positioning jump, so that real-time positioning data is allowed to be more accurate, and the flight path of an aircraft is allowed to be displayed with smoother data.

Description

technical field [0001] The invention relates to a method for removing flight track jumps of aircraft, and belongs to the technical field of aircraft flight track optimization methods. Background technique [0002] With the continuous development and growth of China's aviation industry, problems such as airspace and flow have become more and more prominent. Flight delays and flow control have caused complaints from passengers. The emergence of this new technology, ADS-B, can automatically obtain parameters from relevant airborne equipment and broadcast the aircraft's position, altitude, speed, heading, identification number and other information to other aircraft or ground stations, so that the controller can monitor the status of the aircraft. monitor. [0003] With the increasing popularity of ADS-B in aircraft applications, the feasibility of aircraft position monitoring through ADS-B is becoming stronger and stronger; however, due to the limited range of ADS-B transmissi...
