Description

Technical Field

[0001] This invention belongs to the field of satellite application and control technology, and specifically refers to a satellite-ground collaborative mission control method for Earth observation space cloud services. Background Technology

[0002] Space-ground collaborative mission management utilizes the network resources of the satellite internet project, forming a cloud architecture based on ground-based core nodes, space-based edge nodes, and application terminals. This aggregates various space-based land and sea observation needs, enabling the unified management and use of civilian and commercial satellite remote sensing information resources. Many innovative NASA space missions differ significantly from previous ones in terms of the number of spacecraft, structural configuration, and interactions. For each new mission, the mission application system must be redesigned, resulting in high system development and maintenance costs, low ground system reusability, and difficulties for personnel operating multiple missions simultaneously. Therefore, NASA proposed a new generation of architecture to support deep space and space mission control: the Advanced Multi-Mission Application System (AMMOS). AMMOS utilizes virtualization and software sharing technologies to construct a multi-mission application system architecture, improving system usability and computer resource utilization efficiency. The U.S. Department of Defense, through an open architecture, constructs a system technology architecture that supports modularity, loose coupling, and high tight integration, achieving openness including the public disclosure of key internal interfaces and open design throughout the entire process.

[0003] Analyzing the current state and future trends of task management, the main problems with the current system are as follows:

[0004] (1) Insufficient multi-satellite and multi-user joint mission management capabilities. In response to the diverse needs of civilian and commercial satellites and the usage requirements of multiple departments, companies and other users, the number and complexity of missions have increased dramatically. This has led to a decrease in the adaptability of existing mission planning model algorithms. There are certain gaps in the ability to support multi-user distributed collaborative observation and conflict resolution, as well as the ability to coordinate and cooperate with heterogeneous satellites such as multi-type platform payloads. There is also a lack of interoperability between users (especially in the control of civilian and commercial satellites by military users).

[0005] (2) Insufficient operational and tactical support capabilities. The current satellite control system has a long time span from receiving requests to controlling satellites to execute imaging plans, and from satellites performing observation actions to data transmission back to the ground system. Due to limitations in satellite orbits, observation areas, and the geographical distribution of telemetry and control receiving stations, its timeliness is poor, making it difficult to meet the emergency response requirements for injection, reconnaissance, and transmission in the "five current circles" (current circle injection, current circle reconnaissance, current circle downlink, current circle processing, and current circle distribution). Limited by the number of controllable satellite resources and timeliness issues, there is also a significant gap between the continuous observation capability for moving targets and user requirements.

[0006] (3) The onboard intelligent decision-making level is weak and the degree of space-ground coordination is not high. The current satellite mission generation mechanism usually relies on aerospace experts with relevant field knowledge and rich experience. However, when facing complex and dynamic environmental situations, subjective human factors or judgment errors are often inevitably introduced, making it difficult to continuously ensure the accuracy of decision-making schemes. The onboard autonomous processing capability is insufficient and the degree of space-ground coordination is not high, making it difficult to meet the needs of comprehensive aerospace information application.

[0007] The methods described above do not yet have detailed and specific solutions for managing space-ground collaborative missions based on cloud architecture, and there are many problems in multi-satellite and multi-mission planning, campaign and tactical support, and on-board intelligent decision-making. Summary of the Invention

[0008] To address the aforementioned issues, this invention proposes a space-ground collaborative mission management method for Earth observation space cloud services. This method is suitable for the planning and management of remote sensing satellite constellation missions under a space-ground integrated cloud architecture, exhibiting good autonomy and robustness, and is applicable to fields such as satellite mission planning and management under space-ground collaboration.

[0009] A method for managing space-ground collaborative missions for Earth observation space cloud services includes the following steps:

[0010] Step 1: Based on space and function, the management and control of space-ground collaborative missions are divided into three roles: ground control center, space edge cloud service center, and remote sensing satellite constellation.

[0011] Step 2: After the observation requirement occurs, select the control mode according to the urgency and complexity of the requirement, including the traditional control mode, the ground control-on-board processing mode, and the on-board autonomous mission processing mode.

[0012] Step 3: Generate the mission plan and instructions for the remote sensing satellite constellation and telemetry and control station network in the corresponding mode, and transmit them to the remote sensing satellite constellation and telemetry and control station network for mission execution;

[0013] Step 4: After the task is executed, data is received through the space edge cloud service center and the ground station network.

[0014] Furthermore, step 1 is detailed as follows:

[0015] Step 1a: The ground control center is responsible for accepting all remote sensing observation requests, mission planning and scheme generation under the traditional control mode, request acceptance and mission overall planning under the ground control-on-board processing mode, and request acceptance and mission planning under the on-board autonomous mission processing mode.

[0016] Step 1b: The Space Edge Cloud Service Center is responsible for the processing and distribution of remote sensing data in the ground control-on-board processing mode, and autonomous mission planning, mission distribution, data reception and processing, and data distribution in the on-board autonomous mission processing mode.

[0017] Step 1c: The remote sensing satellite constellation is responsible for receiving instructions, conducting observations, and transmitting data to the space edge cloud service center in various modes.

[0018] Furthermore, step 2 is detailed as follows:

[0019] Step 2a: Determine the complexity of the requirement. If the requirement type is a single point target, it is a simple requirement. If it is multiple point targets or regional targets, it is a complex requirement. If it is other types, it cannot be determined. If it cannot be determined, the user can choose the mode. Simple requirements can choose the on-board autonomous mode, and complex requirements can proceed to the next step.

[0020] Step 2b: Determine the urgency of the need. If it needs to be executed within one day, it is an urgent need. If it is not required to be executed within one day, it is a general need. Urgent needs adopt the ground control-on-board processing mode, while general needs adopt the traditional control mode.

[0021] Step 2c: If the user's observation needs are urgent but the task is complex, select the ground control-on-board processing mode.

[0022] Step 2d: If the user's observation needs are urgent and the task is simple, then directly select the on-board autonomous task processing mode.

[0023] Step 2e: If the user's observation needs are not urgent but the task is complex, then the traditional control mode should be selected.

[0024] Step 2f: If the observation needs generated by the user are not urgent and the tasks are simple and regular, then select the on-board autonomous task processing mode.

[0025] Step 2g: For other requirements, select the appropriate mode based on the resources of the ground control center and the space edge cloud service center.

[0026] Furthermore, step 3 is detailed below:

[0027] Step 3a: If the control mode is on-board autonomous mode, the ground will transmit the requirements to the satellite through the telemetry and control station, and the satellite will carry out mission planning and execution. The mission planning will generate a specific plan for data download and distribution.

[0028] Step 3b: If the control mode is ground control-on-satellite processing mode, the ground will carry out mission planning, generate a specific plan for data download and distribution in the mission planning, and transmit the mission instructions to the master satellite through the telemetry and control station. The master satellite will then schedule other satellites to process the data.

[0029] Step 3c: If the control mode is traditional control, the ground will carry out mission planning, generate a specific plan for data transmission and distribution in the mission planning, and transmit the instructions to the satellite through the telemetry and control station to control the satellite to complete the observation.

[0030] Furthermore, step 4 is detailed below:

[0031] Step 4a: Perform routing analysis on the communication satellites included in the space edge cloud service center to generate downlink links;

[0032] Step 4b: Perform visibility analysis on the ground receiving stations included in the ground station network to generate a specific data reception plan.

[0033] The beneficial effects of this invention are as follows:

[0034] 1. This invention overcomes the shortcomings of existing methods, such as difficulty in coordinating space-ground missions, difficulty in coordinating multiple types of users, and slow data transmission speed, and improves the collaborative management and control performance of remote sensing satellite missions under space-ground integration.

[0035] 2. This invention has good practical application and remote sensing satellite mission planning and control processing performance, and can meet the application requirements of fast, accurate and comprehensive remote sensing satellite mission planning and control. Attached Figure Description

[0040] A method for managing space-ground collaborative missions for Earth observation space cloud services, such as Figure 1 As shown, it includes the following steps:

[0041] Step 1: Divide the space-ground collaborative mission control into three main roles according to space and function, including the ground control center, the space edge cloud service center, and the remote sensing satellite constellation;

[0042] Step 2: After the observation requirement occurs, select the control mode according to the urgency and complexity of the requirement, including the traditional control mode, the ground control-on-board processing mode, and the on-board autonomous mission processing mode.

[0043] Step 3: Generate mission plans and instructions for remote sensing satellite constellations and telemetry and control station networks under different modes, and transmit them to the remote sensing satellite constellations and telemetry and control station networks for mission execution;

[0044] Step 4: After the mission is completed, data is received through the space edge cloud service center and the ground station network.

[0045] like Figure 2 As shown, step 1 is as follows:

[0046] Step 1a: The ground control center is responsible for accepting all remote sensing observation requests, mission planning and scheme generation under the traditional control mode, request acceptance and mission overall planning under the ground control-on-board processing mode, and request acceptance and mission planning under the on-board autonomous mission processing mode.

[0047] Step 1b: The Space Edge Cloud Service Center is responsible for the processing and distribution of remote sensing data in the ground control-on-board processing mode, and autonomous mission planning, mission distribution, data reception and processing, and data distribution in the on-board autonomous mission processing mode;

[0048] Step 1c: The remote sensing satellite constellation is responsible for receiving instructions, conducting observations, and transmitting data to the space edge cloud service center in various modes.

[0049] like Figure 3 As shown, step 2 is as follows:

[0050] Step 2a: Determine the complexity of the requirement. If the requirement type is a single point target, it is a simple requirement. If it is a multiple point target or a regional target, it is a complex requirement. If it is another type, it cannot be determined. If it cannot be determined, the user can choose the mode. Simple requirements should choose the on-board autonomous mode, and complex requirements should proceed to the next step.

[0051] Step 2b: Determine the urgency of the requirement. If it needs to be executed within one day, it is an urgent requirement. If it is not required to be executed within one day, it is a general requirement. Urgent requirements adopt the ground control-on-board processing mode, while general requirements adopt the traditional control mode.

[0052] Step 2c: If the user's observation needs are urgent but the task is complex, select the ground control-on-board processing mode;

[0053] Step 2d: If the user's observation needs are urgent and the task is simple, then directly select the on-board autonomous task processing mode;

[0054] Step 2e: If the user's observation needs are not urgent but the task is complex, then select the traditional control mode;

[0055] Step 2f: If the observation needs generated by the user are not urgent and the tasks are simple and regular, then select the on-board autonomous task processing mode;

[0056] Step 2g: For other needs, the mode can be selected based on the resource availability of the ground control center and the space edge cloud service center.

[0057] Step 3 is as follows:

[0058] Step 3a: If the control mode is on-board autonomous mode, the ground will transmit the requirements to the satellite through the telemetry and control station, and the satellite will carry out mission planning and execution. The mission planning will generate a specific plan for data download and distribution.

[0059] Step 3b: If the control mode is ground control-on-satellite processing mode, the ground will carry out mission planning, generate a specific plan for data downlink and distribution in the mission planning, and transmit the mission instructions to the master satellite through the telemetry and control station. The master satellite will then schedule other satellites to process the data.

[0060] Step 3c: If the control mode is traditional control, the ground will carry out mission planning, generate a specific plan for data transmission and distribution in the mission planning, and transmit the instructions to the satellite through the telemetry and control station to control the satellite to complete the observation.

[0061] Step 4 is as follows:

[0062] Step 4a: Perform routing analysis on the communication satellites included in the space edge cloud service center to generate downlink links;

[0063] Step 4b: Perform visibility analysis on the ground receiving stations included in the ground station network to generate a specific data reception plan.

[0064] In summary, this invention first defines three main roles for space-ground collaborative mission management; second, it selects the management mode based on the urgency and complexity of the requirements; then, it generates mission plans and instructions for the remote sensing satellite constellation and telemetry and control station network, and executes the missions; finally, after mission execution, data is received through the space edge cloud service center and the ground station network, thereby achieving management under a cloud architecture. This method overcomes the shortcomings of existing methods, such as difficulty in coordinating space-ground missions, difficulty in coordinating multiple types of users, and slow data transmission speeds. It improves the collaborative management performance of remote sensing satellite missions under a space-ground integrated system and can meet the application requirements of rapid, accurate, and comprehensive remote sensing satellite mission planning and management.
