China launched a Samsung rocket again. What is its main function?

The satellite is mainly used for scientific experiments, land and resources research, agricultural product evaluation, disaster prevention and mitigation, etc. This time, Samsung was launched from xichang satellite launch center, China. In this launch, we used the Long March 2D launch vehicle. On April 27th, 2006, China's first remote sensing satellite was successfully launched.

Of course, the launch must be effective and the cost is quite high. If not, it will be a waste of people and money. Environmental monitoring is one of the most important applications of satellites, including atmospheric environmental monitoring, water environmental monitoring, solid waste environmental monitoring, marine environmental pollution monitoring and ecological environmental monitoring. By using satellites, we can analyze the changes of the atmosphere and climate, and the monitoring range becomes very large. Remote sensing satellites can use spectrum and other technical means to observe the changes of color and area of water environment. Remote sensing satellites can monitor the location and area of solid waste. Satellites can monitor changes in the ocean, such as the activities of fish in the ocean and the movement of pollutants on the ocean surface.

At the same time, it can also be used for population statistics of land and resources, and satellites can monitor and evaluate cultivated land, construction sites, water bodies, forests and grasslands. According to satellite data, adjust the planning land structure and improve the land utilization rate. Estimated output of agricultural products. The relevant information provided by satellites can be used to evaluate crop yield, understand the changes of planting system and planting structure in specific areas, and adjust the industrial structure of crops.

Flood disaster is difficult to prevent because of its large area and short time, but with the help of satellite scanning equipment, rainfall data is easy to obtain and prepare in advance. By using remote sensing satellites, we can quickly grasp the path and location of typhoons and prevent them in advance. Generally speaking, our country is very skilled in the space industry, and the probability of launch failure is the lowest in the world. The development of the aerospace industry is getting stronger and stronger, which reflects from the side that our country's economic strength is getting stronger and stronger, and its comprehensive national strength can rank first in the world.
