In May 2007, the China National Space Administration became the member of the International Charter Space and Major Disasters, a joint initiative that works to provide emergency response satellite data free of charge to those affected by disasters anywhere in the world.
Each member of the International Charter Space and Major Disasters has demonstrated its commitment to use its space assets when it is most needed, when disasters of natural and human origin strike the worlds communities, or wreak havoc on the environment.
The first stage of the program is comprised of three minisatellites, usually referred to as the 2+1 constellation. The second stage of the program will consist of a total of eight spacecraft (four with optical payloads and four with SAR payloads, the 4+4 constellation). Originally, the launch of all the satellites was to be accomplished by 2012 through international cooperation.
The first stage implementation includes three small satellites (2+1 constellation). The spacecraft of the constellation are referred to as HJ-1A, HJ-1B, and HJ-1C. The HJ-1A and HJ-1B satellites were launched at 03:25UTC on September 6, 2008, by the Chang Zheng-2C/SMA (Y1) launch vehicle from the Taiyuan Satellite Launch Center.
HJ-1A is an optical satellite with a CCD camera and an infrared camera while HJ-1B is equipped with a CCD camera and a hyperspectral camera on board. Each spacecraft has a launch mass of 470 kg, with a size of 1.2 m x 1.1 m x 1.03 m, and a design life of three years.
The satellites were based on the CAST-968B bus of DFHSat (DFH Satellite Co Ltd.) of CAST (China Academy of Space Technology) and by the China Aerospace Science and Technology Corporation. Both satellites are 3-axis stabilized.
The HJ-1C satellite is a spacecraft with an S-band (ТКСА-6К collapsible mesh parabolic antenna) SAR payload based on the CAST-2000 (CAST-968B). The satellite will have a Sun-synchronous circular dawn-dusk orbit, at an altitude of 500 km, 97.3 degrees inclination and a 94 minutes orbital period, with a local time on descending node at 6:00 hours.
The satellite predicted operational life is three years. This is the first civil Synthetic Aperture Radar (SAR) system
The mass of the spacecraft is 890 kg, including 200 kg of its SAR payload. The communications of its payload data will use CCSDS standard to format compressed raw data and its auxiliary data. On board the satellite has 40 Gbit of storage capacity and the transmission is made via X-band downlink with QPSK modulation. The downlink data rate is of 2 x 160 Mbit/s.
Power supply is made by using a solar array with 7.5 m2 using GaAS/Ge solar cells capable of delivering a power of 1.1 kW (BOL) and 0.8 kW (EOL). Power is stored on two batteries (40Ah).
The S-band SAR instrument was developed with the assistance of NPO Mashinostroyenia & Vega Corp. from Russia. The SAR instrument has a 3.13 GHz (S-band) center frequency, corresponding to a wavelength of 9.6 cm, giving a spatial resolution of 20 meters, with a swath width of 100 km.
The SAR instrument will be capable of a two mode operation: Scan Mode and Strip Mode. On Scan Mode it will be able to get a 15 to 25 meter resolution with a swath of 95 to 105 km. The Strip Mode it will be able to get a 4 to 6 meter resolution with a swath of 35 to 40 km.
Other satellites were launched together with Huanjing-1C, the XY Xinyan-1 and the FN-1 Fengniao-1A/B pair.
The Xinyan-1 was build by the Aerospace DFH Development Limited of Shenzhen, the recently established spin-off of CASTs mini-satellite department. The small satellite will test various components such as China-built microwave switches, a lighter user communication terminal and more accurate thermostats to be used of future satellites.
Also known by NewTech-1 (New Technology Demonstration Satellite), the XY-1 is the first new space technology in-orbit demonstration project developed by enterprises in China and used for in-orbit test demonstration of many new technologies.
The FN-1 Fengniao-1A/B (HummerSat-1) satellites represent the first realization of a new generic micro/minisatellite development of DFHSat (DFH Satellite Co. Ltd.).
The overall objective of the mission is to provide a technology demonstration as well as to test observation capabilities within the spacecraft class of 80-250 kg of total mass envelop (micro/minisatellite), for a number of different missions and applications, including support scenarios of constellations and formation flight (with intersatellite crosslink, relative navigation, guidance and control).
The FN-1 mission concept consists of two satellites, the FN-1A with a launch mass of about 160 kg, as the principal spacecraft of the formation, and a microsatellite, the FN-1B with a mass of 30 kg. Both satellites are launch as a uniform body.
On orbit, FN-1B will be deployed to form a two-spacecraft formation with the main spacecraft. Both spacecraft are in contact with a crosslink for information exchange and the enactment of required orbit manoeuvres. However, all ground communications with the formation is only via the mother spacecraft.
The goal of the mission is to demonstrate the newly developed CAST-mini bus and CAST-micro bus designs in space, in particular to validate their functional capabilities and technologies introduced, and to demonstrate the capability of close formation flying technologies such as relative navigation, guidance and control, intersatellite crosslink, and command.
The Fengniao-1A uses a new modular bus concept, referred to as CAST-mini, which is of CAST-968 and CAST-2000 platform heritage. The CAST-mini bus consists of a cylindrical (octagonal) body with face-mounted solar panels and two deployable T-form solar wings, oriented in the ±Y axis.
The spacecraft body has a size of 785 mm in diameter and 1032 mm in height. Thermal control is provided by passive means (radiator) and assisted by active means (heater) when needed. The satellite has a design life of three years. It is 3-axis stabilized with an Earth-pointing orientation, providing medium pointing and pointing-stability accuracies.
Fengniao-1B is a new microsatellite development of DFHSat. The objectives are to test the new modular platform capabilities in space and to use the spacecraft for formation flying demonstrations with FN-1A. The satellite bus features also an octagonal shape (as the mother spacecraft) with dimensions of 400 mm in diameter and 175 mm in height.
The surface-mounted solar cells (GaAs) provide an average power of ~ 5 W. Orbit and attitude control is provided with RCS (Reaction Control Subsystem) using 12 thrusters (each with 30 mN).
Relative orbit measurements between the two satellites are provided with a differential GPS (DGPS) receiver.
The Chang Zheng-2C launch vehicle:
The Chang Zheng-2C a low Earth orbit launch vehicle derived from DF-5 ICBM. The rocket is a two stage hypergolic launch vehicle with a total length of 35.17 meters, a diameter of 3.35 meters and a total mass of 192,000 kg.
This is a liquid launch vehicle mainly used for Low Earth Orbit (LEO) missions. The CZ-2C is most frequently used version of Long March Launch Vehicles which had 14 consecutive successful flights till October of 1994.
In order to meet the users need, China Academy of Launch Vehicle (CALT) developed a new smart dispenser upper stage; the CZ-2C/SD has been used commercially in the late 1990s and conducted seven consecutive successful launches for Iridium program.
The CZ-2C launch vehicle now provides two versions to customers: a basic version composed by a two-stage CZ-2C for LEO missions with typical launch capability of 3,366 kg; and a three-stage version: CZ-2C/CTS for LEO or SSO with typical launch capability of 1,456 kg.
This launcher provides a flexible mechanical and electrical interfaces and length-adjustable fairing for various satellites. The launch environment impinging on the cargo do be launched, such as vibration, shock, pressure, acoustics, acceleration and thermal environment, meets the common requirements in the commercial launch services market.
The first stage is equipped with a cluster of four YF-20A engines (YF-21), having a length of 23.72 meters, a gross mass of 151,000 kg (empty mass of 8,600 kg) and a burn time of 130 seconds.
The second stage is equipped with a cluster of one YF-22A engine with fixed nozzles and a swivelling venire motor consisting of four YF-23 chambers motors (the YF-24), and has a length of 8.71 meters, a gross mass of 38,200 kg (empty mass of 3,200 kg) with a burn time of 112 seconds (main engine) and 287 second (vernier).
In this launch the CZ-2C used an SMA upper stage (possibly using the SpaB-140C solid motor), increasing the SSO payload capability to 1,900 kg.
The Taiyuan Satellite Launch Center:
Situated in the Kelan County on the northwest part of the Shanxi Province, the Taiyuan Satellite Launch Center (TSLC) is also known by the Wuzhai designation. It is used mainly for polar launches (meteorological, Earth resources and scientific satellites).
The center is at a height of 1400-1900m above sea level, and is surrounded by mountains to the east, south and north, with the Yellow River to its west. The annual average temperature is 4-10 degrees C, with maximum of 28 degrees C in summer and minimum of -39 degrees C in winter.

An another video of this launch, we can see how the SAR antenna is deployed... This is the 16th chinese space launch in 2012, and it should have 3 more to come before the end of the year.
In 2013, 16 launches have been planned, especially with the launch of manned spacecraft Shenzhou-10 in earlier June.

China launches new communication satellite:chinasat-12
China launches new communication satellite - Xinhua | English.news.cn
Chinas 18th launch of 2012 sees Long March 3B loft ChinaSat-12 | NASASpaceFlight.com
November 27th, 2012 by Rui C. Barbosa
The Chinese have launched the ChinaSat-12 (Zhongxing-12) communications satellite into orbit via a Long March 3B/E (Chang Zheng-3B/E) on Tuesday their 18th orbital launch of the year. The launch took place at Beijing time 18:13 (10:13 UTC) from the LC2 launch pad at the Xichang Satellite Launch Center.
ChinaSat-12 Mission:
This bird was originally called Apstar-7B, a Spacebus-4000C2 platform geostationary communications satellite, with 24 C-band and 23 Ku-band high power beams. It was contracted to Thales Alenia Space of France for construction, on behalf of APT Satellites, in April of 2010.
Apstar-7B was a back up satellite, in event Apstar-7 failed to make it to orbit. However, the launch carried out on March 31, 2012 was a success, allowing Apstar 7B to be transferred to a secondary agreement between APT Satellites and the China Great Wall Industry Corporation (CGWIC).
With the secondary agreement in place, the satellite was taken by China Satcom a state-owned satellite operator in Beijing and renamed Zhongxing-12 (or ChinaSat-12). Zhongxing-12′s role is to replace Zhongxing-5A (ChinaSat-5A) at 87.5 degrees East.
Zhongxing-12 had a lift-off mass of 5,054 kg and a design lifetime over 15 years. It uses a S400 propulsion system and is equipped with two deployable solar arrays.
Part of the satellites communications payload has been leased to Sri Lanka and is co-branded as SupremeSat-I. Recently, SupremeSat entered into a partnership agreement with CGWIC for the design, manufacturing and launching of the SupremeSat-III satellite and also to secure the marketing facilities of many other satellites owned and operated by CGWIC and the China Satellites Communications Corporation.
This satellite will be based on the DFH-4 platform and will be positioned at 50 degrees East Longitude after being launched by a CZ-3B/E launch vehicle. Supremesat-II will be launched in mid 2013 and will also lease capacity on the Zhongxing-11 (Chinasat-11) Chinese made communications satellite.
Zhongxing-12 will serve the demands of communication, satellite broadcasting, data transmission, digital broadband multimedia system and media streaming services in China, East Asia, South Asia, Middle East, Africa, Australia and China Sea area, and the Indian Ocean region.
The Spacebus 4000-based medium-class telecommunication satellite has a successful flight heritage, and can easily accommodate a large range of payloads in every band (Ku, C, Ka, X, S, L) to satisfy customer needs.
The solar array power offered by the Spacebus 4000 is up to 15.8 kW with a payload power up to 11.6 kW, typically 80 to 100 active channels with medium RF power (105/110W in Ku band), standard equipment and system designs available in Ku/C and Ka frequency bands, while other frequency bands (X, S, L) can be proposed.
Chinas 18th launch in 2012 was also the 173rd successful Chinese orbital launch, the 173rd launch of a Chang Zheng launch vehicle, the 9th launch from Xichang in 2012 and the 77th orbital launch from Xichang.Developed from the Chang Zheng-3A, the Chang Zheng-3B is the most powerful launch vehicle on the Chinese space launch fleet. The Apstar-7 launch was the 23rd flight of CZ-3B and the 55th flight of CZ-3A series launch vehicles.
The CZ-3B features enlarged launch propellant tanks, improved computer systems, a larger 4.2 meter diameter payload fairing and the addition of four strap-on boosters in the core stage that provide additional help during the first phase of the launch.
The rocket is capable of launching a 11,200 kg satellite to a low Earth orbit or a 5,100 kg cargo to a geosynchronous transfer orbit.
The CZ-3B/E (Enhanced Version) launch vehicle was developed from the CZ-3B, increasing the GTO capacity up to 5,500kg. The CZ-3B/E has nearly the same configurations with CZ-3B bar its enlarged core stage and boosters.
On May 14, 2007, the first flight of CZ-3B/E was performed successfully, accurately sending the NigcomSat-1 into pre-determined orbit. With the GTO launch capability of 5,500kg, CZ-3B/E is dedicated for launching heavy GEO communications satellite.
The Xichang Satellite Launch Centre is situated in the Sichuan Province, south-western China and is the countrys launch site for geosynchronous orbital launches.
Equipped with two launch pads (LC2 and LC3), the centre has a dedicated railway and highway lead directly to the launch site. The Command and Control Centre is located seven kilometers south-west of the launch pad, providing flight and safety control during launch rehearsal and launch. The CZ-3B launch pad is located at 28.25 deg. N 102.02 deg. E and at an elevation of 1,825 meters.
Other facilities on the Xichang Satellite Launch Centre are the Launch Control Centre, propellant fuelling systems, communications systems for launch command, telephone and data communications for users, and support equipment for meteorological monitoring and forecasting.
The first launch from Xichang took place at 12:25UTC on January 29, 1984, when the CZ-3 Chang Zheng-3 (CZ3-1) was launched the Shiyan Weixing (14670 1984-008A) communications satellite into orbit.
