[0045] In the current aviation field, common methods for locating and authenticating low-altitude aircraft include using GPS (Global Positioning System) or similar satellite positioning systems to obtain the location information of the aircraft. Aircraft are usually equipped with GPS receivers to receive location signals from satellites and determine their current position, speed, heading and other information based on them. In addition, aircraft usually use communication equipment, such as ADS-B (Automatic Dependent Surveillance-Broadcast) system, to send location information to the ground control console. The ADS-B system enables automatic broadcasting and reception between aircraft, allowing aircraft to detect and track each other, and send location and identity information to the ground control console.

[0046] However, the above existing methods lack effective verification of the location and identity of low-altitude aircraft, and there is a risk of low-altitude aircraft identity forgery or misreporting of location, which affects communication security.

[0047] In view of the above-mentioned defects of the prior art, the present invention provides a method for authenticating low-altitude aircraft, wherein the method obtains the aircraft position information reported by the target aircraft and the beacon information reported by the avionics system, and determines a first verification result according to the aircraft position information and the beacon information, wherein the beacon information includes position information and identification information; when the first verification result is passed, the aircraft position information and the beacon information are verified according to the pre-stored standard aircraft parameters and flight plan corresponding to the target aircraft, and a second verification result is determined; when the second verification result is passed, the aircraft position information is verified based on the intersensory base station data, and a third verification result is determined. The present invention solves the problem that the prior art lacks effective verification of the position and identity of low-altitude aircraft, and there is a risk of identity forgery or misreporting of the position of low-altitude aircraft, resulting in affected communication security, by performing triple verification of the aircraft position information and identification information.

[0048] Exemplary methods:

[0049] like Figure 1 As shown, the method includes:

[0050] Step S100, obtaining the aircraft position information reported by the target aircraft and the beacon information reported by the avionics system, and determining a first verification result according to the aircraft position information and the beacon information, wherein the beacon information includes identification information and position information.

[0051] Specifically, the target aircraft is the aircraft whose identity information and location information are to be verified, and the target aircraft may be a drone, an airplane, a helicopter, etc. Figure 2 As shown, the target aircraft is equipped with an avionics system and an aircraft information reporting module, wherein the aircraft information reporting module is responsible for reporting the aircraft position information, which includes the longitude, latitude, altitude, speed, etc. of the target aircraft; the avionics system is used to automatically report beacon information. The beacon information contains the identification information and position information (longitude, latitude, altitude, and speed information, etc.) of the target aircraft, wherein the speed information includes the speed and heading of the target aircraft. The airline ground control center is responsible for monitoring and managing the ground settings of the aircraft. When the target aircraft reports the aircraft position information and beacon information, the airline ground control center receives and processes the information and communicates with other ground equipment.

[0052] In one implementation, after receiving the aircraft position information and beacon information, the aircraft position information and beacon information are processed by the primary information verification module, and the position information in the aircraft position information and the beacon information are compared. When the difference between the aircraft position information and the position information in the beacon information is within a preset range, the first verification result is determined to be passed; when the difference between the aircraft position information and the position information in the beacon information is greater than the preset range, the first verification result is determined to be failed. When the first verification result is failed, the aircraft position information and beacon information can be obtained again for verification. When the number of consecutive failures of the first verification result exceeds the preset number, the aircraft position information is analyzed for abnormalities.

[0053] like Figure 1 As shown, the method further comprises the following steps:

[0054] Step S200: When the first verification result is passed, obtain the pre-stored standard aircraft parameters and flight plan corresponding to the target aircraft, verify the aircraft position information and the beacon information according to the standard aircraft parameters and the flight plan, and determine the second verification result.

[0055] When the first verification result is passed, after receiving the beacon information and aircraft position information of the target aircraft, the standard aircraft parameters and flight plan corresponding to the pre-stored target aircraft are retrieved from the database. The standard aircraft parameters are the standard parameters of the target aircraft after leaving the factory. The flight plan is the expected flight plan corresponding to the current time of the target aircraft, and the flight plan includes the flight path, expected starting time, expected flight time, etc. The beacon information and aircraft position information are verified according to the standard flight parameters and flight plan to obtain the second verification result. This embodiment verifies the beacon information and aircraft position information according to the standard aircraft parameters and flight plan through the first-level information verification module to ensure the accuracy and consistency of the position information and identification information of the target aircraft.

[0056] In one implementation, the standard aircraft parameters include identification parameters and speed parameters, and the verifying the aircraft position information and the beacon information according to the standard aircraft parameters and the flight plan to determine the second verification result includes:

[0057] Step S201: verifying the position information of the aircraft based on the speed parameter and the flight plan, and determining a position verification result;

[0058] Step S202: verify the beacon information based on the identification parameter and determine an identification verification result;

[0059] Step S203: Determine the second verification result according to the position verification result and the identification verification result.

[0060] Specifically, the identification information and aircraft position information of the target aircraft are verified according to the identification parameters and speed parameters in the standard aircraft parameters and the flight plan. The identification parameters are the standard identification information corresponding to the target aircraft. The identification parameters are compared with the identification information in the beacon information to obtain the identification verification result to achieve identity authentication of the target aircraft. When the identification parameters are consistent with the identification information in the beacon information, the identification verification result is passed; when the identification parameters are different from the identification information in the beacon information, the identification verification result is failed. This embodiment ensures the legitimacy of the identity of the target aircraft by checking whether the identification parameters and the beacon information are consistent through the identity authentication algorithm.

[0061] Speed ​​parameters include the target aircraft's corresponding airspeed, ground speed, and Mach number. Based on the speed parameters and the flight plan, the estimated position of the target aircraft in a certain period of time can be obtained, and the estimated position is compared with the aircraft position information to obtain the position verification result. When the difference between the estimated position and the aircraft position information is within the preset range, the position verification result is passed; when the difference between the estimated position and the aircraft position information is not within the preset range, the position verification result is failed.

[0062] When both the identification verification result and the location verification result are passed, the second verification result is passed; when the identification verification result or the location verification result is failed, the second verification result is failed.

[0063] In one implementation, verifying the aircraft position information based on the speed parameter and the flight plan and determining a position verification result includes:

[0064] Step S2011, determining a position range according to the speed parameter and the flight plan;

[0065] Step S2012: verify the aircraft position information based on the position range and determine the position verification result.

[0066] Specifically, the expected position range of the target aircraft in each time period of flight is estimated according to the speed parameter and the flight plan. In this embodiment, the maximum flight speed and the minimum flight speed of the target aircraft are obtained according to the speed parameter, and the flight time of the target aircraft is obtained through the flight plan. The expected position range of the target aircraft is estimated according to the maximum flight speed, the minimum flight speed and the flight time. The verification algorithm is used to determine whether the aircraft position information is within the expected position range and whether it is consistent with the flight plan or the scheduled route. If the aircraft position information is within the expected position range and is consistent with the flight plan or the scheduled route, the verification algorithm outputs a position verification result of pass; otherwise, the verification algorithm outputs a position verification result of fail.

[0067] like Figure 1 As shown, the method further comprises the following steps:

[0068] Step S300: When the second verification result is passed, the synesthesia base station data is obtained, and the aircraft position information is verified based on the synesthesia base station data to determine a third verification result.

[0069] 5G-A (5G-Advanced, 5G-enhanced version) communication and perception integrated technology combines multiple capabilities such as communication, perception, and computing. While ensuring communication services, it gives base stations radar-like perception and detection capabilities, and can achieve low-cost, blind-spot-free, all-weather perception of low-altitude flying objects. Since the 5G-A intersensory base station can timely and accurately identify flying objects entering the base station signal coverage area and track their trajectories, this embodiment uses the 5G-A intersensory base station to actively search and scan aircraft in the low-altitude area, and identify and classify aircraft based on the data obtained by the sensor, distinguish different types of aircraft, and extract their feature information, such as the location information and speed of the aircraft, and use the obtained aircraft category and the extracted feature information as intersensory base station data.

[0070] When the second verification result is passed, this embodiment receives the aircraft position information of the target aircraft sent by the first-level information verification module and the synesthesia base station data sent by the synesthesia base station through the second-level information verification module, and performs data cleaning on the aircraft position information and the synesthesia base station data to ensure the consistency of the data format; uses an information comparison algorithm to compare and analyze the aircraft position information and the synesthesia base station data to check whether parameters such as position information and speed are consistent, so as to ensure the accuracy and effectiveness of the target aircraft identity authentication and position verification.

[0071] In one implementation, verifying the aircraft position information based on the telepathic base station data to determine a third verification result includes:

[0072] Step S301, determining the deviation error corresponding to the target aircraft according to the telepathic base station data and the aircraft position information;

[0073] Step S302: Obtain a deviation error threshold, and determine a third verification result according to the deviation error threshold and the deviation error.

[0074] In simple terms, when the difference between the aircraft position information reported by the target aircraft and the position information in the telepathic base station data is small, it is judged that the aircraft position information reported by the target aircraft is accurate and has not been tampered with. In this embodiment, the deviation error corresponding to the target aircraft is calculated based on the position information in the telepathic base station data and the aircraft position information, and the deviation error is compared with the deviation error threshold to obtain a third verification result. If the deviation error is less than or equal to the deviation error threshold, the third verification result is passed; if the deviation error is greater than the deviation error threshold, the third verification result is not passed. In this embodiment, by calculating the deviation error based on the telepathic base station data and the aircraft position information, and then determining the third verification result based on the deviation error, it can effectively detect problems such as information being stolen or tampered with, resulting in identity forgery or misreporting of position, or when the aircraft is based on GPS positioning, it is interfered with or blocked by the signal, resulting in the accuracy and integrity of the reported aircraft position information being affected.

[0075] In one implementation, the method for determining the deviation error threshold includes:

[0076] Obtaining a number of historical deviation errors, and determining a deviation error mean and a deviation error standard deviation according to the number of historical deviation errors;

[0077] Real-time environmental data is acquired, and the deviation error threshold is determined according to the real-time environmental data, the deviation error mean, and the deviation error standard deviation.

[0078] Specifically, this embodiment obtains historical deviation errors, calculates the deviation error mean and the deviation error standard deviation based on the historical deviation errors, and measures whether the deviation error of the target aircraft is within a normal range by using the deviation error mean and the deviation error standard deviation. At the same time, in order to more accurately evaluate the position information of the target aircraft, different deviation error thresholds are calculated by using the real-time environmental data (strong wind, heavy rain, cloudy, sunny, etc.) of the current position of the target aircraft during the calculation of the deviation error threshold.

[0079] In one implementation, determining the deviation error threshold according to the real-time environmental data, the deviation error mean, and the deviation error standard deviation includes: , is the deviation error threshold, is the deviation error mean, is the adjustment coefficient, is the standard deviation of the deviation error, The correction item determined based on the real-time environmental data may also be dynamically adjusted based on a comparison result between the real-time deviation error and the historical deviation error.

[0080] In one implementation, the parameters of the target aircraft type (such as drones, civil aircraft, helicopters, etc.) are introduced to set the adjustment coefficient. The model of the target aircraft may be determined based on the aircraft position information corresponding to the target aircraft or the standard aircraft parameters.

[0081] In one implementation, the method further includes:

[0082] When the second verification result or the third verification result is failure, analyzing the aircraft position information to determine an abnormal behavior pattern corresponding to the target aircraft;

[0083] The target aircraft is subjected to abnormal processing according to the abnormal behavior pattern.

[0084] Specifically, when the second verification result fails, the primary processing verification module sends the aircraft position information to the exception handling module, or when the third verification result fails, the secondary information verification module sends the aircraft position information to the exception handling module. After receiving the aircraft position information, the exception handling module uses machine learning and data mining technology to analyze the aircraft position information and detect possible abnormal behavior patterns, such as target aircraft deviation, incorrect target aircraft identification information, incomplete position information, etc. According to the detected abnormal behavior pattern, corresponding exception processing is performed, including sending alarm information, adjusting the detection strategy of the target aircraft, etc., so as to further improve the accuracy and safety of aircraft positioning.

[0085] Based on the above embodiments, the present invention also provides a low-altitude aircraft authentication device, such as Figure 3 As shown, the device comprises:

[0086] The first verification module 01 is used to obtain the aircraft position information reported by the target aircraft and the beacon information reported by the avionics system, and determine a first verification result according to the aircraft position information and the beacon information, wherein the beacon information includes identification information and position information;

[0087] The second verification module 02 is used for obtaining the pre-stored standard aircraft parameters and flight plan corresponding to the target aircraft when the first verification result is passed, verifying the aircraft position information and the beacon information according to the standard aircraft parameters and the flight plan, and determining a second verification result;

[0088] The third verification module 03 is used to obtain the telepathic base station data when the second verification result is passed, verify the aircraft position information based on the telepathic base station data, and determine a third verification result.

[0089] Based on the above embodiment, the present invention further provides a terminal, whose principle block diagram can be shown as follows: Figure 4 As shown. The terminal includes a processor, a memory, a network interface, and a display screen connected through a system bus. Among them, the processor of the terminal is used to provide computing and control capabilities. The memory of the terminal includes a non-volatile storage medium and an internal memory.
