What meteorological satellites are there in China?
Fengyun-1 is China's first sun-synchronous orbit meteorological satellite, which can obtain global meteorological data and is mainly used for weather forecast, climate prediction, natural disasters and environmental monitoring. Fengyun-2 is the first generation of quasi-stationary orbit meteorological satellite in China, which can provide continuous meteorological data with high time resolution and is mainly used for weather forecast, climate forecast, natural disaster monitoring and military reconnaissance.
Fengyun-3 is the second generation polar-orbiting meteorological satellite in China, which can obtain global meteorological data and is mainly used for weather forecast, climate forecast, natural disaster monitoring and environmental monitoring. Fengyun-4 is the second generation geostationary meteorological satellite in China, which can provide regional meteorological data with high time resolution and is mainly used for weather forecast, climate forecast and environmental monitoring.
Fengyun-5 and Fengyun-6 are the third generation polar-orbiting meteorological satellites in China. They will further expand the series scale of China polar-orbiting meteorological satellites, and will be mainly used in the fields of weather forecast, climate forecast, natural disaster monitoring and environmental monitoring.
Components of meteorological satellites:
1. Satellite platform: This is the main structure of the satellite, which is responsible for providing energy, attitude control, temperature control and other functions to ensure the normal operation of the satellite.
2. Payload: This is the instrument and equipment responsible for observing and monitoring the atmospheric environment on the satellite, including infrared radiometer, scanning radiometer, microwave radiometer and cloud image camera.
3. Data transmission system: This is an important part of transmitting observation data from satellite to ground station, generally using radio transmission.
4. Ground control system: This is a ground system for controlling and managing satellites, including ground stations, control centers and data processing centers.
5. Data processing system: This system is used to process observation data, including data receiving, processing, analysis and distribution.
6. Energy system: This is the equipment that provides energy, generally using the combination of solar panels and batteries.
7. Thermal control system: This equipment is used to control the internal temperature of the satellite and ensure the normal operation of instruments and equipment.
