This satellite is in the end what is backing?
Who can be big! This is called satellite Fengyun No. four A star, December 11, 2016 successfully
launched at the Xichang satellite launch center. As China's new generation of geostationary
meteorological satellite from the first generation (and number two) across to the second
generation of the first star, and number four to ensure the static meteorological services in China
continuous, reliable and stable operation, improve China's aerospace industry, is of great
significance to meteorological enterprise's international status and influence.

I do not understand? Never mind. You only need to remember, whether it is in May this year,
north sand, or at the end of June to early July in the South "merbok" typhoon, or after the "The
Belt and Road forum, it has played an important role in meteorological monitoring.
Let's see how serious it is!

Let's see how serious it is!
Stride across
First of all, the development of the whole satellite of FY four satellite has reached the
international advanced level, and has realized the leap of our geostationary orbiting
meteorological satellite from "running" and "running" to "leading"
Specific performance where? FY four satellite to fill the 3 international blank: achieved the
Specific performance where? FY four satellite to fill the 3 international blank: achieved the
world's first geostationary interferometric hyperspectral atmospheric detection; the world's first
radiometer, lightning detector, instrument platform loading, all day long work; the world's first
geostationary microwave detection technology for the first time validation, 425GHz band
detection.
Secondly, this star also won the first time on the domestic real-time compensation navigation
Secondly, this star also won the first time on the domestic real-time compensation navigation
registration, the first high sensitive instrument, multiple micro vibration suppression and
measurement, the first high-precision spectral calibration and full spectrum section, in orbit
radiometric calibration, such as 7 first

They can effectively improve the weather forecast and climate prediction level and enhance
They can effectively improve the weather forecast and climate prediction level and enhance
the ability to monitor the ecological environment by obtaining multispectral, high-precision,
quantitative observation data and images of the earth's surface and clouds
Take lightning monitoring, it loaded the lightning imaging sensor developed independently by

China, one minute can shoot 500 lightning, lightning detection range of frequency and
intensity, so as to realize the monitoring and tracking for the strong convective weather,
provide lightning disaster warning, this is the first application in China.
In addition, compared with the number two and number four, imaging time resolution is
In addition, compared with the number two and number four, imaging time resolution is
doubled. Single star can be completed and number two star network, in order to achieve the
full 15 minutes in the 1000 disc imaging. X 1000 km within the region, more than observation
ability and number two, just 3 minutes. With this new Europe a generation of geostationary
meteorological satellite, equal ability.
This is not, in the system of observation ability, and number four has also significantly
This is not, in the system of observation ability, and number four has also significantly
improved: (1) eyes sharp -- spatial resolution of up to 500 meters high; (2) to reflect more
agile regional observation time resolution up to 1 minutes; (3) a higher spectral resolution,
can see the air and surface features more; (4) we can analyze the atmospheric temperature
and humidity acquisition -- atmospheric three-dimensional structure.
