CZ-4Bwas successfully launchedfor the second time within one week, together with HJ-2Aand HJ-2B Satellites
CZ-4B was successfullylaunched at Taiyuan Satellite Launch Center at 11:23 on September 27, together with HJ-2A and HJ-2B Satellites in a mode of “two satellites with one rocket”.
As two earth-observation optical remote-sensing satellites, HJ-2A and HJ-2B Satellites are used to replace theHJ-1A and HJ-1B Satellites that have been in orbit for 12 years, meeting the application needsof the Ministry of Emergency Management and the Ministry of Ecological Environment, and also taking the demands inland and resources, water conservancy, agriculture, forestry and earthquake and other industries into considerations.
The satellites were developed by Aerospace Dongfanghong Satellite, Ltd., Shenzhen .of China Space Technology Academy affiliated China Aerospace Science and Technology Corporation, with the same technical state, and 5-year designed service life. In addition, each satellite is equipped with 4 types of optical loads.
The two satellites can obtain the ground images fast by networking based on the geosynchronous orbit, and will largely improve our capacity to obtain medium-resolution visible light, IR and hyperspectral data, and meet our urgent need for the continuous supply of remote sensing data in relevant sectors.
After HJ-2A and HJ-2B Satellites were put into the orbit, they will form a collaborative network with GF-1 and GF-2. This is the first integrated collaboration between satellite projects of environment and disaster monitoring small satellites, and synchronous satellites willincrease our satellite utilization rate, and make our earth observation and remote-sensing applications more effective as a whole.
Developed by Shanghai Academy of Spaceflight Technology, CD-4B is a room-temperature liquid level III carrier rocket that can be applied in launching different types of satellites with different orbit requirements.
With a tandem-engine carrier cabinbeing added based on thebasic fairing, HJ-2A and HJ-2B Satellites were put into the preset sun-synchronous orbit inthe tandem-engine manner with two satellites
CZ-4B was recently launched on Monday this week (September 21), and succeeded in launching HY2-03 Satellite at Jiuquan Satellite Launch Center.
This is the 348th flight of the Long March series of carrier rockets, and also the 124th flying test of the Long March series of carrier rockets developed by Shanghai Academy of Spaceflight Technology.
