The launch dates and types of these satellites

Dongfanghong-2A

The Dongfanghong-2A practical communication and broadcast satellite was successfully launched on March 7, 1988. The satellite was fixed at 87.5° east longitude. The satellite is equipped with 4 C-band communication transponders, which can carry out 4-channel television broadcasts, a telephone transmission capacity of 3,000 channels, and a design life of 4.5 years.

Ziyu-1

The satellite is an earth resources satellite jointly developed by China and Brazil, also known as "China-Brazil Earth Resources Satellite-1". In the 1990s, China and Brazil reached an intergovernmental agreement to jointly develop an earth resources satellite to fill the gaps between the two countries in related fields. The first Ziyuan-1 satellite 01 was launched from the Taiyuan Satellite Launch Center on October 14, 1999 by a Long March 4B carrier rocket. After the successful launch of the satellite, a large amount of earth data and satellite images of the relevant areas were obtained for China and Brazil, and it played an important role in agriculture, forestry, oceans, environmental protection, land resources, urban planning and other aspects.

"Fengyun" No. 1

The FY-1 satellite formed an overall preliminary plan in 1977 and carried out comprehensive development work. In October 1985, the FY-1 satellite project was included in the key projects of satellite model development during the "Seventh Five-Year Plan" period.

Fengyun-1 satellite is the first generation of quasi-polar sun-synchronous orbit meteorological satellite independently developed by my country, and it is also my country’s first transmission-type polar orbit remote sensing satellite. Its main mission is to obtain domestic and foreign atmosphere, cloud, land, and ocean data, and collect relevant data for use in weather forecasting, climate prediction, natural disasters, and global environmental monitoring. The satellite can send real-time meteorological cloud images to cloud image receiving stations around the world, and can also detect ocean water color and conduct remote sensing research on sea temperature; the satellite carries a space particle composition monitor, which can conduct research on the space environment. Currently, Japan has launched four, codenamed: FY-1A, FY-1B, FY-1C and FY-1D.

Fengyun-2

The meteorological satellite (FY-2) is the first geostationary orbiting meteorological satellite independently developed by my country. It complements the polar orbiting meteorological satellite and constitutes the application of my country's meteorological satellites. system.

"Practice" No. 5

The SJ-5 satellite is my country's first small application satellite using common platform technology, and its structure adopts a subdivision design. For the first time, a central computer is used on the satellite to unify the electronic equipment on the satellite.

"Shijian" 8

At 15:00 on September 9, 2006, our country used the "Long March 2C" carrier rocket at the Jiuquan Satellite Launch Center to successfully launch the "Shijian 8" The breeding satellite is sent into a predetermined orbit. Satellites are mainly used for space breeding experiments and research.
