Description

Technical Field

[0001] This invention relates to the field of aerospace simulation training scenario deployment and analysis technology, and in particular to a method, system, equipment and medium for synchronizing aerospace simulation training scenario deployment and analysis. Background Technology

[0002] In the simulation scenario, we need to simulate confrontation exercises with different training equipment. The director will issue simulation scenario information so that different training parties can simulate offensive and defensive confrontation in the same aerospace environment.

[0003] Existing technologies for real-time transmission of scenario data, achieving multi-training adversarial exercises by synchronously distributing core data such as simulation scenarios, satellite models, and orbital parameters, have the following drawbacks: 1) The data packets are large in size and transmitted frequently, easily causing network congestion and resulting in the loss of critical data; 2) The retransmission mechanism for lost data packets relies on ACK confirmation responses, requiring the construction of complex message verification and state recovery logic; 3) The system's high coupling leads to strong dependencies between functional modules, requiring the reconstruction of the core transmission module when expanding to new equipment types or adjusting adversarial rules; 4) The real-time response mechanism lacks flexible control, and the situation updates from the opponent's training perspective cannot achieve tactical-level delayed feedback, weakening the realism of the exercises.

[0004] An existing invention application with application number 202411780802.9 proposes a digital twin simulation system and method for high-orbit, highly maneuverable satellite countermeasures. While this solution ensures the effectiveness of the experiment and the feasibility of its spaceborne application, shortens the experimental cycle, and reduces the risks and costs, it is prone to network congestion leading to the loss of critical data. The retransmission mechanism for lost data packets relies on ACK confirmation responses, requiring the construction of complex message verification and state recovery logic. Furthermore, the situational updates from the opponent's training perspective cannot achieve tactical-level delayed feedback, thus weakening the realism of the exercise.

[0005] For the reasons mentioned above, there is a need for a method to synchronize scenario distribution and analysis in aerospace simulation training, which can improve the efficiency of receiving scenario information (satellite model, ground station model, orbital parameter model, and sensors) from all parties during training, and can also delay the updating of the maneuvering status of the other party's training model from different training perspectives. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to provide a method, system, device, and medium for the synchronous transmission and analysis of aerospace simulation training scenarios. By defining the data transmission structure through data processing units and specifications, the scenario simulation system is decoupled, thus unifying the data structure for the transmission of interactive scenarios.

[0007] This invention provides a method, system, equipment, and medium for the synchronous release and analysis of aerospace simulation training scenarios.

[0010] S2. During adversarial training, both sides process the acquired scenario information to generate scenario model data and satellite model data, respectively.

[0011] S3. Both sides load scenario model data and satellite model data for adversarial training and conduct adversarial drills.

[0012] S4. The maneuver information of one side in the confrontation exercise is sent to the other side after a delay by the directing party.

[0018] Optionally, the step of generating scene model data includes:

[0019] S31. Receive basic scene information, including scene start time, end time, and creation time.

[0020] S32. Set the scene name, load the satellite model data, and store the satellite model data in the scene model map.

[0021] Optionally, the satellite maneuvering configurations in the confrontation include escort flight, circling flight, waterdrop hovering, and waterdrop skimming flight.

[0022] Optionally, the maneuver information for the adversarial exercise includes information on maneuvering and orbit changing of the satellite based on the illumination angle, satellite mission type, and distance to the target satellite.

[0023] Optionally, when the maneuver information of one side in the confrontation exercise is sent to the other side after a delay by the director, the director sets the delay time for the maneuver information.

[0024] The second aspect: a system for synchronously disseminating and analyzing aerospace simulation training scenarios, including:

[0025] The directing unit is used to notify both sides of the confrontation training to obtain the scenario information and to forward the maneuver information of one side to the other side.

[0026] The data processing unit is used to process the acquired scenario information by both sides in the adversarial training, and generate scenario model data and satellite model data respectively to form an adversarial simulation scenario;

[0027] The red team unit is used to generate maneuver information for attack and counterattack in adversarial simulation scenarios.

[0028] The blue team unit is used to generate maneuver information for defensive countermeasures in adversarial simulation scenarios.

[0029] Third aspect: An electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the program, performs the steps of the method provided in the first aspect.

[0030] Fourth aspect: A non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the method provided in the first aspect.

[0031] The beneficial effects of this invention are:

[0032] 1. The aerospace simulation training scenario deployment and synchronization method and system proposed in this invention adopt a unified deployment of basic information of the simulation scenario and data of satellites, ground stations, orbits and sensors by the director; both sides in the adversarial training acquire data through the data processing unit and construct dynamic model mapping relationships, and use the orbit predictor for synchronous initialization; it supports the real-time acquisition of the training side's own satellite maneuver parameters during the adversarial process, while the opponent's training receives status updates with a delay set according to permissions; the lightweight data transmission mechanism improves the efficiency and security of information interaction, and provides a standardized basis for the expansion and adaptation of different systems.

[0033] 2. This invention replaces the traditional high-frequency transmission mode of WebSocket with a lightweight and modular data transmission mechanism (such as structured data encapsulation and independent data processing units), which significantly reduces network bandwidth pressure and reduces the risk of data loss. At the same time, it simplifies the logic of restoring lost data through standardized data interfaces and improves the overall transmission reliability.

[0034] 3. This invention introduces an independent data processing unit and defines a unified data interaction structure to decouple the director system from the training adversarial system, reduce inter-system dependencies, and the modular design supports flexible expansion of new functions to adapt to different simulation scenario requirements, thereby enhancing system decoupling and scalability.

[0035] 4. This invention supports the trainee to synchronize the maneuver parameters (such as trajectory change commands) of their own equipment in real time, while the opponent receives status updates based on preset delay rules. This not only meets the real-time response requirements of offensive and defensive confrontation, but also simulates the information lag of real battlefield through the delay mechanism, thereby improving the realism of the exercise. Administrators can dynamically adjust the delay parameters to enhance the controllability of the confrontation process.

[0036] 5. This invention advances the satellite orbit data generation process by using orbit parameter modeling and forecaster pre-calculation technology, reducing the real-time computing load; at the same time, it utilizes the model type-ID mapping relationship to achieve rapid loading and updating of scene data, reducing memory usage, reducing resource consumption, and optimizing computing efficiency.

[0037] 6. The standardized transmission structure of this invention is compatible with multiple communication protocols (such as RESTful), and combined with access control mechanisms (such as delayed access rules for remote data), it reduces the risk of sensitive data leakage and improves the security of multi-system integration. Security and compatibility are guaranteed. Attached Figure Description

[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] The existing real-time transmission of scenario data has the following problems: the data packets are large and the transmission frequency is high, which can easily cause network congestion and lead to the loss of critical data; the retransmission mechanism for lost data packets relies on ACK confirmation and requires the construction of complex message verification and state recovery logic; the system is too coupled, resulting in strong dependencies between functional modules, and the core transmission module needs to be reconstructed when expanding to new equipment types or adjusting the adversarial rules; the real-time response mechanism lacks flexible control, and the situation update from the opponent's training perspective cannot achieve tactical-level delayed feedback, which weakens the realism of the exercise.

[0043] To address the above problems, this invention provides a method for synchronously disseminating and analyzing aerospace simulation training scenarios. Figure 1A flowchart illustrating a method for synchronously disseminating and analyzing aerospace simulation training scenarios provided in an embodiment of the present invention, the method comprising:

[0044] S1. The director issues a notice to both sides to conduct simulated training and obtain scenario information.

[0045] The scenario information includes: basic scenario information, satellite model information, ground station model information, orbital parameter model information, and sensor information.

[0047]

[0048]

[0049] As shown in Table 1, the object names are divided into: Scene, Satellite Set, Ground Station Set, and Sensor Set. The Scene, Satellite Set, and Ground Station Set are classified as first-level objects, with the Scene being the parent of the Satellite Set and Ground Station Set. The Sensor Set is classified as a second-level object, with the Satellite Set and Ground Station Set being the parent of the Sensor Set.

[0050] The scenarios, satellite sets, ground station sets, and sensor sets have corresponding code types: Scenario, satellite, device, and sensor, respectively.

[0051] The attributes corresponding to a scenario include:

[0052] Scene name (name), scene start and end times (startTime, stopTime), and scene children ({sate:[sateId],device:[deviceId,sensor:sensorId]}).

[0053] The attributes corresponding to a satellite swarm (Scenario) include: orbital information (orbit), attitude (attitude), and display (display).

[0054] The attributes corresponding to the ground station collection (device) include: location information (location), description (desc), and display (show).

[0055] The attributes corresponding to a sensor set include: definition, pointing, and show.

[0056] The scenario basic information is the global control framework for aerospace simulation and confrontation exercises. By defining the spatiotemporal reference, environmental parameters, training configuration, and inference rules, it serves as the context environment for the operation of other models, including the time axis, spatial reference, training configuration, and environmental parameters.

[0057] Satellite models describe the spacecraft entities in various training exercises during aerospace simulation and confrontation, including static attributes, dynamic behaviors, and adversarial relationships. They are the core objects of attack and defense simulations. They include basic satellite attributes such as mass and propellant reserves; satellite dynamic attributes such as initial orbit, current state, and payload switching; and relationship mappings such as training affiliation and adversarial targets.

[0058] The ground station model represents the ground telemetry and control facilities of each training party, and is responsible for satellite command uplink, telemetry data reception and adversarial task scheduling, including geographical location, communication capabilities, task queues and visibility windows.

[0059] The orbital parameter model describes the spatiotemporal motion of the satellite, including the initial orbital state and dynamic correction data in real-time simulations, such as initial orbital parameters, real-time orbital parameters, perturbation model, and maneuver command parameters.

[0060] S2. During the adversarial training, both sides process the acquired scenario information to generate scenario model data and satellite model data, respectively.

[0061] Based on the basic scenario information, a spatiotemporal adversarial benchmark is defined. Both sides in the adversarial training load orbital parameter models and sensors based on satellite model information and ground station model information, forming scenario model data and satellite model data for both sides, thus constructing an adversarial simulation scenario. Specifically:

[0062] If the received data is satellite model data, then the basic satellite attributes are assembled, the satellite orbit data is calculated using the forecaster, and the satellite model data is stored in the scene model map. The code implementation is as follows:

[0063]

[0064] If it's basic scene information, then assemble the scene start time, end time, and creation / initialization time, save the scene data, and set the scene's model type and corresponding model ID map to null. The code implementation is as follows:

[0065]

[0066]

[0067] S3. Both sides load scenario model data and satellite model data for adversarial training and conduct adversarial drills.

[0068] The combat exercises included close-range reconnaissance and imaging, with configurations such as escort flight, circling flight, teardrop hovering, and teardrop skimming flight, among others:

[0069] Close-range reconnaissance involves maneuvering and changing the orbit of a satellite to shorten the relative distance to the target satellite to the effective range of optical or electronic reconnaissance payloads, thereby achieving high-precision situational awareness of the target.

[0070] The Hohmann transfer orbit can be calculated based on the orbital parameter model, and visible light, infrared or synthetic aperture radar sensors can be activated by sensors to transmit the configuration parameters and operational status of the target satellite in real time.

[0071] Imaging operations utilize onboard optical payloads to perform visible light or multispectral imaging of designated space targets, generating space image data with a resolution better than 0.3 meters. The imaging geometry can be calculated based on a ground station model, the satellite's three-axis pointing can be adjusted through the attitude control module, the optical distortion correction algorithm of the sensor can be applied, and the data can be transmitted back using a compressed and encrypted transmission protocol.

[0072] Collision attack: By maneuvering its own satellite into a collision trajectory with the target satellite, it uses kinetic energy to physically destroy the target satellite.

[0073] The optimal collision trajectory can be calculated based on the Lambert algorithm, and the trajectory parameter model can be used to generate avoidance warnings, activate the propulsion system to perform maneuvers, and monitor the collision probability in real time.

[0074] Targeted strikes are attacks that use spaceborne energy weapon systems (such as lasers and microwaves) to carry out soft / hard kill attacks on targets.

[0075] The directed energy device can be activated by sensors, the effective range can be calculated using an atmospheric attenuation model, a closed-loop control system can be used to maintain beam focus, and a power gradient attack can be carried out.

[0076] S4. The maneuver information of one side in the confrontation exercise is sent to the other side after a delay by the directing party.

[0077] During training and adversarial combat, equipment can be maneuvered and adjusted based on illumination angle, equipment mission type, and distance to target satellites to generate maneuver information. This information is then used for specific configuration operations such as escorting, circling, hovering, and skimming. The specific code for implementing this maneuver information is as follows:

[0078]

[0079]

[0080] The method of this invention is designed for aerospace simulation training and exercises, enabling dynamic confrontation simulations of multiple training teams (director, red team, and blue team) in a unified aerospace environment, and achieving real-time or delayed synchronization of models such as satellites, ground stations, orbital parameters, and payloads.

[0081] This invention also provides a system for synchronizing the release and analysis of aerospace simulation training scenarios, such as... Figure 2 As shown, the system includes: a director unit, a data processing unit, a red team unit, and a blue team unit, etc., wherein:

[0082] The directing unit is used to notify both sides of the adversarial training to obtain the scenario information and forward the maneuver information of one side to the other side; the data processing unit is used by both sides of the adversarial training to process the obtained scenario information and generate scenario model data and satellite model data respectively to form an adversarial simulation scenario; the red team unit is used to generate maneuver information for attack adversarial combat in the adversarial simulation scenario; the blue team unit is used to generate maneuver information for defense adversarial combat in the adversarial simulation scenario.

[0083] The director unit loads a preset scenario template (such as scene basic parameters and equipment type rules), sends the scenario information to the red or blue team, and performs maneuver information relay. It receives real-time maneuver messages from the red or blue team and applies a delay strategy: such as a fixed delay of 200ms or a dynamic delay, such as automatically increasing or decreasing the delay by ±50ms based on network load. The processed maneuver information data is then forwarded through a multicast channel.

[0084] The data processing unit parses the scenario information, instantiates the satellite model, and constructs the adversarial scenario.

[0085] The red and blue units can maneuver and adjust their orbits according to the illumination angle, equipment mission type, and distance to the target satellite, generating maneuver information and producing offensive or defensive strategies respectively, and performing specific configuration operations such as escorting, circling, hovering, and skimming.

[0086] This invention relates to a scenario-based synchronous distribution method and system for aerospace simulation training. The director uniformly distributes basic information about the simulation scenario, along with data from satellites, ground stations, orbits, and sensors. The trainee acquires this data through modular interfaces and constructs dynamic model mapping relationships, using an orbit predictor for synchronous initialization. During adversarial training, the system supports real-time acquisition of friendly satellite maneuver parameters (such as orbit change commands), while the opposing trainee receives status updates with a delay set according to their permissions. This method improves information exchange efficiency and security through a lightweight data transmission mechanism, while also providing a standardized foundation for expansion and adaptation to different systems.

[0087] The present invention also provides an electronic device, Figure 3 This is a schematic diagram of the structure of an electronic device provided in an embodiment of the present invention, such as...
