[0002] In airport operations command systems, the ability to display aircraft taxiing positions on a map in real time and with high accuracy is crucial. However, relying solely on traditional positioning data such as Automatic Dependent Surveillance-Broadcast (ADS-B) has several insurmountable technical limitations. For example, data can experience jitter and stuttering; map displays can become stagnant during signal loss; and they are susceptible to interference from outliers (drift points). Currently, the industry commonly uses simple moving averages or low-pass filtering to address these issues, but these methods have significant shortcomings. They are ineffective when data is lost and exhibit lag in handling severe outliers, failing to meet the requirements for smooth trajectory display.

[0023] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description
[0024] The accompanying drawings are provided to further illustrate the present application and form part of the specification. They are used together with the embodiments of the present application to explain the application and do not constitute a limitation thereof. In the drawings: Figure 1 This is a flowchart of an aircraft trajectory display method according to an embodiment of this application; Figure 2 This is a flowchart of aircraft trajectory data processing in one embodiment of this application; Figure 3 This is a schematic diagram of the structure of an aircraft trajectory display device according to an embodiment of this application; Figure 4 This is a schematic diagram of the hardware structure of an aircraft trajectory display system according to one embodiment of this application. Detailed Implementation
[0025] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0026] Figure 1 This is a flowchart of an aircraft trajectory display method according to an embodiment of this application, such as... Figure 1 As shown, the method can be implemented as follows: S101-S104: In step S101, during the aircraft's movement, the aircraft's sequence positioning data is received and recorded; In step S102, the two latest consecutive valid positioning points are obtained from the sequence positioning data; In step S103, the motion vector of the aircraft is calculated based on the two latest consecutive valid positioning points, the motion vector including the direction of movement and the speed of movement; In step S104, before receiving a new positioning point, based on the motion vector, multiple intermediate position points are inserted and displayed periodically at the front-end rendering frame rate to make the aircraft icon produce a smooth moving visual effect.
[0027] During aircraft movement, the system receives and records the aircraft's sequential positioning data. The two most recent consecutive valid positioning points are obtained from this data, and the aircraft's motion vector, including the direction and speed of movement, is calculated based on these two points. For example, valid positioning point P1 (longitude X1, latitude Y1) and point P2 (X2, Y2) of aircraft A are received. The system calculates the direction of movement α and the speed V from P1 to P2. At this point, the aircraft icon begins to move from P1 to P2.
[0028] Before receiving a new location point, multiple intermediate position points are inserted and displayed periodically based on the motion vector and the front-end rendering frame rate to create a smooth visual effect for the aircraft icon. The number of intermediate position points is dynamically calculated based on the front-end rendering frame rate and the time interval between subsequent arrivals of location points; these intermediate position points are then inserted and displayed according to the calculated number. In the example above, the original location data is sent every 1.5 seconds, while the front-end rendering frame rate is 60 times per second (i.e., 60Hz), meaning the screen needs to be updated approximately every 16.7 milliseconds. If rendering is based directly on the original location data, with only one new data point every 1.5 seconds, the screen would remain in the same position for nearly 1.5 seconds before suddenly "jumping" to the next point, causing noticeable stuttering and a jerky feel. In this application, during the 1.5-second wait for P3 after receiving P2, the system calculates 90 intermediate positions based on the movement direction α and movement speed V, and updates the icon position every 16.7 milliseconds. This results in a continuous and smooth movement process for the user.
[0029] In this application, when a new location point is received, an anomaly check is performed on the new location point. That is, while waiting for a new valid location point, when the system receives a new location point P_ new When (X', Y') is reached, anomaly detection is initiated to determine whether the new location point is a valid location point. In one embodiment, a geofencing determination is performed on the new location point: First, it is determined whether the new location point exceeds a predefined flight area geofence. For example, by comparing the coordinates of the new location point with the coordinate range of a preset flight area, it is determined whether the new location point exceeds the effective geographical boundary of the preset flight area (such as a runway or taxiway). Then, when the new location point exceeds the predefined flight area geofence, the new location point is determined to be an anomaly. In another embodiment, a distance / speed threshold determination is performed on the new location point: The distance between the new location point and the previous valid point, and the aircraft speed calculated based on the new location point are determined. When the distance between the new location point and the previous valid point is greater than a preset distance, or when the aircraft speed calculated based on the new location point is greater than a preset speed, the new location point is determined to be an anomaly. Based on the valid location point P_ prevTo the new location point P_ new The coordinates are used to calculate the distance between two points. When the distance between the new positioning point and the previous valid point is greater than the preset distance, the new positioning point is determined to be abnormal. In addition, the receiving time of the two points can be combined to calculate the corresponding aircraft speed. When the aircraft speed calculated based on the new positioning point is far greater than the reasonable speed of the aircraft taxiing on the ground, it can also be determined to be abnormal. Figure 2 This is a flowchart of aircraft trajectory data processing in one embodiment of this application, as shown below. Figure 2 As shown in this embodiment, after obtaining a new location point, a geofence determination is first performed, and then a distance / speed threshold determination is performed on the new location point to determine whether the new location point is abnormal.
[0030] When the judgment result indicates that the new positioning point is an anomaly, the new positioning point is discarded, and interpolation display continues based on the motion vector. When the new positioning point P_ new If it is an outlier, discard P_ new The aircraft icon continues to move based on the previously calculated motion vector, gliding along its original direction and speed.
[0031] When the judgment result indicates that the new location point is not an anomaly, the new location point is determined as a new valid location point; the aircraft icon is then smoothly moved from the previously interpolated position to the new valid location point through animation. When the system receives a valid location point P3(X3,Y3), the icon may have already moved to position P according to the prediction. predicted At this point, the system will not instantly jump to P3, but will instead initiate a brief animation (e.g., 0.3 seconds). Similarly, the midpoint of each frame can be calculated using linear interpolation, allowing the icon to transition from P to P3. predicted The transition to the actual P3 point is smooth and animated. This process is quick and natural, and the user can hardly perceive the correction process, only feeling that the movement is always smooth.
[0032] Because aircraft exhibit different motion curves under different motion states, this application intelligently judges the severity of changes in its motion state by real-time monitoring of the aircraft's dynamic parameters and dynamically adjusts the calculation strategy and rendering frequency of the trajectory processing algorithm to adapt to the needs of different flight phases. Specifically, the system continuously monitors the aircraft's positioning data, including velocity, acceleration, and direction. The positioning data is compared with corresponding thresholds to determine whether the change in the aircraft's motion state exceeds a preset threshold. These thresholds are determined through pre-simulation experiments, taking into account the physical characteristics of aircraft ground taxiing (such as maximum turning angular velocity). The system can determine whether the change exceeds the preset threshold by comparing a single parameter; when the real-time change of any parameter exceeds the corresponding threshold, an adjustment mechanism is triggered. Alternatively, multiple parameters can be combined to determine whether the change exceeds the preset threshold, avoiding misjudgments caused by a single anomaly. When the change in the aircraft's motion state exceeds the preset threshold, the system dynamically adjusts the calculation method and interpolation frequency of the motion vector based on the aircraft's motion state. Specifically, the dynamic adjustment of motion vector calculation is performed as follows: During uniform linear motion, a simple two-point linear motion vector calculation is used; while during acceleration or turning, parameters such as acceleration and turning angle are introduced, and a more complex motion model is used to calculate the motion vector to more accurately reflect the actual motion of the aircraft. The dynamic adjustment of interpolation frequency is performed as follows: When the change in the aircraft's motion state is less than a preset range, i.e., when the aircraft's motion state is stable, a lower interpolation frequency can be used to reduce computation; when the change in the aircraft's motion state is greater than the preset range, indicating a significant change in the aircraft's motion state, the interpolation frequency is increased to more accurately capture the aircraft's motion details, ensuring the smoothness and accuracy of the trajectory display. For example, during intense motion, a higher-order prediction algorithm (such as Kalman filtering considering acceleration) is used; during stable motion, basic linear prediction is used; in high-dynamic states, the interpolation frequency is increased (e.g., from 60Hz to 120Hz) to ensure trajectory accuracy; in low-dynamic states, the frequency is reduced to save computational resources.
[0033] This application utilizes an interpolation algorithm to create continuous animation effects during data intervals, completely resolving the "stuttering" and "jumping" issues caused by data transmission frequency, improving display smoothness, and enhancing user experience and situational awareness quality. During data processing, the dual criteria of geofencing and physical rules effectively identify and mask location drift points, ensuring the rationality and reliability of the displayed position and avoiding misleading information caused by data anomalies. Furthermore, through an anomaly discarding mechanism and smooth convergence, the final presented real-time position and historical trajectory are guaranteed to approximate the aircraft's actual movement path as closely as possible, providing a high-quality data foundation for data insight and analysis. In summary, this application organically combines prediction (interpolation), filtering (anomaly detection), and rendering (smooth transition) into a collaborative technical closed loop, improving data reliability and ensuring display smoothness.
[0034] The beneficial effects of this application are as follows: During aircraft movement, the sequential positioning data of the aircraft is received and recorded, and the two latest consecutive valid positioning points are obtained from the sequential positioning data; the motion vector of the aircraft is calculated based on the two latest consecutive valid positioning points, and the motion vector includes the direction of movement and the speed of movement; before receiving a new positioning point, multiple intermediate position points are inserted and displayed based on the motion vector at a period of front-end rendering frame rate, so that the aircraft icon produces a smooth movement visual effect. Since this application determines the motion vector based on two consecutive valid positioning points, predicts the actual continuous movement trend of the aircraft between the two points, and dynamically and densely calculates and draws multiple intermediate position points through an interpolation algorithm, the continuously calculated intermediate points are rendered on the screen in real time, solving the "stuttering" and "jumping" problems caused by the data transmission frequency, and significantly improving the smoothness of aircraft trajectory display.
[0035] In one embodiment, the method may also be implemented as follows: steps A1-A2: In step A1, when a new location point is received, an anomaly judgment is performed on the new location point; In step A2, when the judgment result indicates that the new positioning point is an abnormal point, the new positioning point is discarded, and interpolation display continues based on the motion vector.
[0036] In one embodiment, the method may also be implemented as steps A3-A4: In step A3, when the judgment result indicates that the new positioning point is not an abnormal point, the new positioning point is determined to be a new valid positioning point; In step A4, the aircraft icon is smoothly moved from the position calculated by the previous interpolation to the new effective positioning point through an animated transition.
[0037] In one embodiment, step A1 above can be implemented as steps A11-A12: In step A11, it is determined whether the new location point exceeds the predefined flight zone geofence; In step A12, when the new location point exceeds the predefined flight zone geofence, the new location point is determined to be an anomaly.
[0038] In one embodiment, step A1 above can be implemented as steps B1-B2 as follows: In step B1, the distance between the new positioning point and the previous valid point is determined, as well as the aircraft speed calculated based on the new positioning point; In step B2, when the distance between the new positioning point and the previous valid point is greater than a preset distance, or when the aircraft speed calculated based on the new positioning point is greater than a preset speed, the new positioning point is determined to be an abnormal point.
[0039] In one embodiment, inserting and displaying multiple intermediate position points in step S104 above can be implemented as follows: steps C1-C2: In step C1, the number of intermediate position points is dynamically calculated based on the front-end rendering frame rate and the time interval between subsequent positioning points not being reached. In step C2, the intermediate position points are inserted and displayed according to the calculated number of intermediate position points.
[0040] In one embodiment, the method may also be implemented as steps D1-D3: In step D1, the aircraft's positioning data is continuously monitored, including speed, acceleration, and direction; In step D2, the positioning data is compared with the corresponding threshold to determine whether the change in the aircraft's motion state is greater than a preset threshold. In step D3, when the change in the aircraft's motion state exceeds a preset range, the calculation method and interpolation frequency of the motion vector are dynamically adjusted according to the aircraft's motion state.
[0041] For example, dynamic adjustment may include: selecting to use a linear motion vector model between two points or a motion model that incorporates acceleration and steering angle for calculation based on the motion state.
[0042] In one embodiment, the method for calculating the dynamic adjustment of the motion vector described in step D3 above can be implemented as follows: During the uniform linear motion phase, a simple linear motion vector between two points is used for calculation; while during the acceleration or turning phase, parameters such as acceleration and turning angle are introduced, and a more complex motion model is used to calculate the motion vector in order to more accurately reflect the actual motion of the aircraft.
[0043] In one embodiment, the dynamic adjustment of the interpolation frequency described in step D3 above can be implemented as follows: When the change in the aircraft's motion state is less than the preset range, i.e. when the aircraft's motion state is stable, a lower interpolation frequency can be used to reduce the amount of calculation. However, when the change in the aircraft's motion state is greater than the preset range, it indicates that the aircraft's motion state has changed significantly. In this case, the interpolation frequency should be increased to more accurately capture the details of the aircraft's motion and ensure the smoothness and accuracy of the trajectory display.
