RS(RemoteSensing) is the abbreviation of remote sensing, which is a new technology developed on the basis of aerial photography in the early 1960s. Started for aerial remote sensing, since 1972, the United States launched the first land satellite, marking the beginning of the era of space remote sensing.
After decades of rapid development, remote sensing technology has been widely used in resources and environment, hydrology, meteorology, geology and geography and other fields, and has become a practical and advanced space exploration technology. Remote sensing refers to non-contact and long-distance detection technology.
Generally, it refers to the detection of electromagnetic radiation and reflection characteristics of objects by sensors/remote sensors. Remote sensing is to detect the target object by remote sensors and other instruments sensitive to electromagnetic waves under the condition of being far away from the target and not touching the target object.
Development course:
On August 19, 2004, the Russian Space Agency recently announced the federal space plan, and the following three types of satellites will be deployed in the future. The first category is Earth resources satellites, which will enable Russia to enter the world space service market and develop some customers in developing countries.
The second category is meteorological disaster observation satellite, which will monitor global atmospheric changes and climate anomalies within 15 minutes to 30 minutes; The third category is meteorological and heliophysical observation satellites, which aim to obtain real-time information of the atmosphere, the surface, the global ocean and the polar ice sheets, so as to map and monitor the evolution process of the ocean, continental shelf and land.
