Abstract

The invention proposes a ground operation control network system for space-based global real-time continuous monitoring. The ground operation control network system comprises a satellite operation control node, a task scheduling node, an image processing node, a product distribution node and a virtual satellite node. According to the invention, satellite-ground task allocation is configured againbased on work characteristics, so that the research and development efficiency is improved effectively and the cost is lowered while the system performance and timeliness are improved substantially. The ground operation control network system can be used for building a low-cost satellite network system for global multi-point real-time video surveillance and high-value moving target tracking. A sensitive area can be monitored continuously; a high-resolution video can be transmitted to the ground in real time; the moving path of the target can be tracked dynamically; and the disaster evaluationis carried out in real time. Moreover, business intelligence information as well as accurate weather forecasting information of a cell can be obtained in real time; and disaster assessment, emergencyrescue, and exploration assistance can be carried out.

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, in particular to a ground operation and control network system suitable for space-based global real-time continuous monitoring. 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 reconnaiss...
