Description

Technical Field

[0001] The present invention relates to the field of satellite application data processing, and in particular to a distributed satellite communication networking information assurance system and method for a satellite network and a ground application network. Background Art

[0002] Currently, with the continuous development of remote sensing satellite payload technology and measurement and control technology, remote sensing satellite imaging mechanisms cover a variety of forms, including visible light imaging, infrared imaging, and synthetic aperture radar imaging. Earth imaging resolution has reached sub-meter levels, fully meeting the needs of ground target observation. Therefore, the integration of remote sensing satellite networks with ground application networks has broad application prospects.

[0003] With the continuous deepening of high-tech development, the form of ground application network has gradually developed from single to diversified, and the distribution style of ground application network has gradually changed from single-point centralized distribution to multi-domain and multi-point distribution. The ground application network's perception demand for remote information is constantly increasing, and the efficiency requirements for remote sensing satellite information interaction are constantly improving.

[0004] However, the remote sensing satellite network and the ground application network are two different types of networks with different security protection levels. The relevant security protection regulations require that a reliable security barrier be established between the two. For example, the existing invention patent application document with publication number CN114944864A is titled "A method for secure and efficient transmission of remote sensing satellite raw code stream data across network areas". The existing method includes the following steps: (1) receiving satellite raw code stream data in the form of data stream according to the satellite tracking reception plan, packetizing the received satellite raw code stream data according to the characteristics of the satellite, and generating data packet files in accordance with the predefined file naming rules; (2) constructing a comprehensive scheduling model for cross-network transmission of raw code stream data under multi-task conditions, scheduling multiple unidirectional transmission devices to perform multi-task parallel cross-network transmission of remote sensing satellite raw code stream data packet files, thereby packetizing remote sensing satellite raw code stream data. The packet file is exchanged from the low-density area to the high-density area; (3) After the high-density area receives the data sub-packet, it parses the satellite model, transmission task, transmission order and priority of the data sub-packet according to the predefined file naming rules, and pushes the data sub-packet to the data processing system in a stable order according to the satellite model and priority for product production; (4) If there is a data sub-packet that is out of sequence or fails to be received, a failure feedback file is generated. The failure feedback file includes the task, priority and data sub-packet name of the data sub-packet. The data sub-packet is exchanged from the high-density area to the low-density area through the optical disk shuttle device. After the low-density area receives the failure feedback file, it parses it and retransmits the data sub-packet that failed to be transmitted from the low-density area to the high-density area. And the existing invention patent application document "A satellite-ground integrated quantum key distribution network and its networking method" with publication number CN111555864A. In the new network of the present invention, it includes a satellite network and a ground network. The satellite network includes a quantum satellite and a quantum satellite ground station unit, and the ground network includes a ground node unit. The quantum satellite ground station unit includes a quantum satellite ground station, a quantum key generation terminal, and a quantum key network exchange device for quantum key relay distribution. The ground node unit includes a quantum key generation terminal and a quantum key network exchange device for quantum key relay distribution. The satellite network also includes a quantum key network exchange strategy and service system for managing the routing strategy of the quantum key network exchange device in the satellite network. The ground network also includes a quantum key network exchange strategy and service system for managing the routing strategy of the quantum key network exchange device in the ground network. Network isolation includes one or more of dual network card isolation, network gateway device isolation, and optical disk ferry isolation. Using the aforementioned existing technology, the ground application network's demand for remote remote sensing observation information can only be met by using a mobile remote sensing satellite terminal vehicle as an accompanying support method. The information exchange between the mobile remote sensing satellite terminal vehicle and the ground application network requires the use of an optical disk ferry, which has a very low information flow efficiency and makes it difficult for remote remote sensing observation information to be effectively and real-timely delivered to the ground application network.At the same time, the multi-domain and multi-point distribution of the ground application network also places demands on the number of mobile remote sensing satellite terminal vehicles, making it difficult to centrally manage remote sensing satellite observation missions. To effectively enhance the remote sensing satellite network's ability to provide satellite remote sensing observation information to the ground application network, these issues urgently need to be addressed.

[0005] Currently, satellite resources are only supported by mobile remote sensing satellite terminal vehicles for ground weapon platform command networks. Communication between these vehicles and the ground application network relies on optical disks, resulting in inefficient information flow. Furthermore, the multi-domain, multi-point distributed firepower approach requires a large number of mobile satellite terminal vehicles, hindering the centralized management of satellite remote sensing observation missions. To effectively enhance the remote sensing satellite network's ability to provide satellite remote sensing observation information to the ground application network, these issues urgently need to be addressed.

[0006] In summary, the existing technology has technical problems such as low information flow efficiency, poor real-time performance of remote sensing information, and difficulty in unified management. Summary of the Invention
