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] At present, with the continuous development of remote sensing satellite payload technology and measurement and control technology, remote sensing satellite imaging mechanisms cover multiple forms such as visible light imaging, infrared imaging, and synthetic aperture radar imaging. The resolution of ground imaging has reached the sub-meter level, which is fully capable of meeting the needs of observing ground targets. It can be seen that the networking and application of remote sensing satellite networks and 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 increasing.

[0004] However, the remote sensing satellite network and the ground application network are two types of networks with different natures and different security protection levels. Relevant security protection regulations require the establishment of a reliable security barrier between the two. For example, the existing invention patent application document "A method for safe and efficient transmission of remote sensing satellite raw code stream data across network areas" with publication number CN114944864A, 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 the 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 subpacket, the satellite model, transmission task, transmission order and priority to which the data subpacket belongs are parsed according to the predefined file naming rules, and the data subpacket is pushed 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 subpacket that is out of sequence or fails to be received, a failure feedback file is generated, which includes the task, priority and data subpacket name of the data subpacket, and is exchanged from the high-density area to the low-density area through the optical disk ferry device. After the low-density area receives the failure feedback file, it is parsed and the data subpacket that failed to be transmitted is retransmitted 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 includes a satellite network and a ground network in the new network of the present invention. 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, and 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, which is responsible for the routing strategy of the quantum key network exchange device in the satellite network; and the ground network also includes a quantum key network exchange strategy and service system, which is responsible for the routing strategy of the quantum key network exchange device in the ground network. Among them, network isolation includes one or more of dual network card isolation, network gate device isolation, and CD ferry isolation. The use of the above-mentioned existing technology can easily lead to the use of mobile remote sensing satellite terminal vehicles to meet the needs of the ground application network for remote remote sensing observation information. The information interaction between the mobile remote sensing satellite terminal vehicle and the ground application network needs to adopt the CD ferry method, and the information flow efficiency is very low. It is difficult for the remote remote sensing observation information to land on the ground application network in real time and effectively.At the same time, the multi-domain and multi-point distributed ground application network also puts forward requirements on the number of mobile remote sensing satellite terminal vehicles, which is not convenient for the centralized and unified management of remote sensing satellite observation tasks. In order to effectively improve the satellite remote sensing observation information guarantee capability of the remote sensing satellite network for the ground application network, the above problems need to be solved urgently.

[0005] The current satellite resource support ground weapon platform command network can only be provided by mobile remote sensing satellite terminal vehicles. The information communication between the mobile remote sensing satellite terminal vehicle and the ground application network needs to be carried out by optical disk ferry, and the information flow efficiency is very low. At the same time, the multi-domain and multi-point distributed firepower strike method also puts forward requirements for the number of mobile satellite terminal vehicles, which is not convenient for the centralized and unified management of satellite remote sensing observation tasks. In order to effectively improve the satellite remote sensing observation information support capability of the remote sensing satellite network to the ground application network, the above problems need to be solved urgently.

[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
