Yaogan

Yaogan Weixing is a set of Chinese Earth observation satellites.

The satellite

Yaogan Weixing -1 or Remote Sensing Satellite No.. 1, according to military designation Jian Bing -5 ( JB -5) is a Chinese satellite that was given by the People's Liberation Army in order. The development took place at the Shanghai Academy of Space Flight Technology. He was taken on 26 April 2006 at 22:48 UTC without notice with a Long March 4B carrier rocket from the Baikonur Taiyuan into a sun -synchronous orbit. After the initial orbit with 601 x 621 km x 97.8 ° was reached, he lifted from April 29 to May 1, its orbit to 628 x 629 km x 97.8 ° at.

Yaogan Weixing -2 ( Jianbing 6) was on 25 May 2007 with a 2.5 kg, with an infrared sensor, a CMOS camera and an S - band transceiver equipped picosatellites ( Zheda Pixing 1 or MEMS - Pico ) the brought Chenyang University with a Long March 2D rocket into a 631 x 655 km orbit with inclination of 97.8 °. This is probably a technically related satellites, but uses an optical camera instead of the SAR radar.

Yaogan Weixing -3 is a 11 November 2007 -started with a LM -4C rocket satellite of the same series as Yaogan 1 He was placed in a 613 x 623 km orbit at 97.9 ° inclination.

Yaogan Weixing -4 was launched on 1 December 2008 with a LM -2D 04:42 UTC from Baikonur Jiuquan in a 633 x 652 km orbit at 97.9 ° inclination. It belongs to the same series as Yaogan -2.

Yaogan Weixing -5 ( Jianbing 8) was launched on December 15, 2008 with a LM -4B at 03:22 UTC from Baikonur Taiyuan into a 519 x 520 km orbit with inclination of 97.6 °. It is a satellite with optical monitoring technology, which does not, however, corresponds to the Yaogan -2, 4 series.

Yaogan Weixing -6 ( Jianbing 7) was launched on 22 April 2009 with a LM -2C at 02:55 UTC from Baikonur Taiyuan into a 519 x 520 km orbit with inclination of 97.6 °. It involves a satellite with radar surveillance technology.

Yaogan 7 was launched on 9 December 2009 with a LM -2D at 08:42 UTC from Baikonur Jiuquan.

The launch of Yaogan 8 took place on 15 December 2009 from the Baikonur Taiyuan with a CZ -4C.

Yaogan Weixing -9 was launched on 5 March 2010 with a CZ -4C from Jiuquan spaceport. The payload fairing was greater than in previous launches, so that it may constitute a new type. Subsequently, it was known that at the start of three satellites ( Yaogan Weixing -9A, 9B and Yaogan Weixing - Yaogan Weixing - 9C) were placed in orbit.

Yaogan Weixing -10 was launched on 9 August 2010 with a CZ -4C from Jiuquan spaceport. The satellite was exposed to a polar, sun-synchronous orbit at an altitude 607-622 km. The orbital inclination to the equator is 97.8 degrees, is therefore slightly.

Yaogan Weixing -11 was launched on 22 September 2010 with a CZ -2D from Jiuquan spaceport.

Yaogan Weixing -12 was launched on November 9, 2011, and corresponds to the type Yaogan 5

Yaogan Weixing -13 was launched on 29 November 2011, and corresponds to the type Yaogan 6

Yaogan Weixing -14 was launched on 10 May 2012 and is an optical satellite.

Yaogan Weixing -15 was launched on 29 May 2012, with a missile of the type Long March 4C and corresponds to the type Yaogan 8 The satellite was on a nearly circular polar orbit with an orbital altitude of 1200 km and an inclination of 100.1 degrees discontinued.

Technology

The government says that it should be about 2700 kg scientific satellite serving the surveying of mineral resources and harvests. The data could also improve the prediction of natural disasters. For this they have, the first Chinese satellite, a Synthetic Aperture Radar on board, which provides images of unknown sharpness. It is not known what frequency the radar operates. Also, you should have a movable solar panel, which can be controlled from the ground station.
