Civil aircraft GPS signal interference real-time analysis and alarm method, electronic equipment, storage medium and program product

Abstract

The invention provides a civil aircraft GPS signal interference real-time analysis and alarm method. The method comprises the steps that: airborne track information of the same aircraft is sequentially received according to a time sequence; receiving the position information of a current track point ; calculating the speed of the current track point, and calculating the speed and direction of the last track point; comparing the speeds and directions of the two track points, and if the difference value of the speeds or directions does not exceed a threshold value, skipping to the step of receiving the position information; and if the difference value of the speeds or the directions exceeds the threshold value, judging whether the flight is in a GPS interfered state, if so, identifying that the GPS interfered state of the flight is ended, and otherwise, identifying that the GPS interfered state of the flight is started. The invention relates to electronic equipment, a storage medium, and a program product. According to the civil aircraft GPS signal interference real-time analysis and alarm method, the electronic equipment, the storage medium and the program product, features and laws in airborne track data are analyzed in real time, the moment and the position of GPS interference of an aircraft are checked and determined, quick response can be achieved when GPS interference just occurs, ground interference sources are checked and processed immediately, and normal operation of flights is recovered as soon as possible.

Description

technical field [0001] The invention relates to the technical field of GPS signal interference analysis and troubleshooting, in particular to a civil aircraft GPS signal interference real-time analysis and alarm method, electronic equipment, storage media and program products. Background technique [0002] At present, the rapid development of communication technology, the popularization and development of wireless communication technology has brought a lot of convenience to the society. However, many radio stations that have not been reviewed and approved by relevant departments are also in use, as well as radio stations assembled by some radio amateurs privately, radio signal jammers and other equipment for various personal purposes are constantly emitting radio signals. If a civil aircraft passes near the above-mentioned sources of interference during flight, various radio equipment used on the aircraft may be interfered, thereby affecting the normal and safe operation of ...

AI Technical Summary

Problems solved by technology

The flight crew usually reports GPS interference to the civil aviation safety management department after the flight lands. The delay in reporting is not conducive to timely investigation of the source of interference and the elimination of potential safety hazards as soon as possible. At present, most interferences have not seriously affected flight operations when they occur. Some flights did not report GPS interference, so the actual flight interference information held by the civil aviation safety management department is not comprehensive enough

[0005] At present, some domestic airports collect data from on-board GPS receivers for landing flights to confirm whether the flights are interfered by GPS, but not all aircraft types can receive them. There are not many airports with such systems, and they need to be released after the day's flight ends. Summarize the data to the local civil aviation management department. This kind of auxiliary technical means also has the defects of time lag and incomplete data
