Embodiment Construction

[0030] The space-based global real-time continuous monitoring network system proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The embodiment of the present invention provides a space-based global real-time continuous monitoring network system, including a satellite-ground dual-cluster network system composed of small satellite clusters and ground server clusters. The small satellite cluster consists of a network of mass-produced small satellites, relying on relay imaging to achieve uninterrupted and continuous video surveillance of multiple regions in the middle and low latitudes of the world. The ground server cluster is the computing and processing core of the entire network. It conducts online real-time remote control of the small satellite cluster, and at the same time receives remote sensing data, processes it, and distributes it to users in real time through Interne...

Abstract

The invention provides a space-based global real-time continuous monitoring network system, comprising a small satellite cluster and a ground server cluster. The small satellite cluster includes an imaging node, a communication node, a standby nods and an offline node, and a relay imaging is used to achieve continuous video surveillance in many regions of the world. The ground server cluster includes a satellite operation and control node, a task scheduling node, an image processing node, a product distribution node and a virtual satellite node. The real-time remote control of the whole network satellite node is realized by using inter-satellite link, and remote sensing data is received, processed and distributed to users in real-time by Internet operation mode. Because the satellite-ground task division is reconfigured according to the work characteristics, the system efficiency and timeliness can be greatly expanded, and the research and development production efficiency can be effectively improved and the cost can be reduced. Continuous monitoring of sensitive areas, real-time transmission of high-resolution video to the ground, tracking the moving path of dynamic targets, and real-time disaster assessment can be achieved.

Description

technical field [0001] The invention relates to an earth remote sensing imaging system, in particular to a network system for space-based global real-time monitoring function, specifically a space-based global real-time continuous monitoring network system. Background technique [0002] In recent years, with the advancement of satellite technology and the increase in demand for remote sensing applications, high-resolution remote sensing applications will be deeply integrated with navigation and positioning, mobile Internet, Internet of Things, smart cities, and information warfare in the future, enabling aerospace applications to play a wider range of effectiveness. The application of high-resolution remote sensing satellite data in the future requires not only high resolution, but also more timely, high-frequency, and more effective information acquisition. In order to overcome the problems of low-orbit high-resolution optical reconnaissance satellites with narrow width and...
