This article is all about the Shiyan Satellite that is launched China, to know more about the Shiyan Satellite read the article given below,
China’s Shiyan Satellite
China Civilian surveillance satellite wanted to make a satellite with a weight around 204 kg and they named the mission ‘Experiment Satellite’. This would be the first Chinese Transmission type satellite of small size capable of carrying stereo mapping.
They started making the experiment satellite in 2004, and they launched their first satellite in April 18th, 2004, and this satellite was known as Tansuo-1. This satellite was made as per their demand and was successfully made of 204 kg.
This mission was jointly designed by the Harbin Polytechnic University, Changchun Polytechnic Institute of the Chinese Academy of Science, Chinese Research Institute of Space Technology and Xian Surveys and Design Institutes.
Before it was planned
This mission seems to have been derived from the Tansuo-1 high resolution imaging microsatellite developed by the Harbin Institute of Technology and was later announced in early June 2000.
This satellite and the mission was planned to launch around in 2001, but then this satellite or the mission was never seen. Tatsuo-1 was a 150 kg microsatellite with a 10 meter stereo resolution camera installed. This satellite was developed with the great collaboration with European Astrium Corporation.
The satellite was mainly made to carry out and take a photographic survey of China’s resources, mainly the land covered by China. The second aim was to monitor its geographical environment and had an aim of scientific mapping research of China and the World.
This mission was handed over to the Satellite Remote Sensing ground station based on CAS followers into the on-orbit testing.
After, November 20, 2011 this satellite stopped working and was brought back to the earth.
Since China needed to make a satellite that replaces the Tansuo-1 and have an aim that would have the mass of 204 kg, this aim and mission gave birth to the Chinese Famous Satellite known as Shiyan.

Birth Of Shiyan Satellite
Shiyan had the main aim of collecting the information about the resources and taking the photos of the China land. This satellite was finally made at 204 kg, with a USAF code of 37931 and apogee around 803 km and perigee around 784 km with an inclination of 98.50 degree.
Shiyan Satellite actually was made as a test satellite that was first launched when Tianhou was officially launched by China, the year was the same 2004.
This satellite were often non sequential and have been developed to have a long-range, this satellites were also made by the Harbin Institution of Technology.
China now have around 10 Shiyan satellite and are also in Sun-synchronous and geo synchronous orbits.
The newest mission that was launched under the Shiyan mission were Shiyan 10 that was launched in September 2021. This satellite remains in the geosynchronous transfer orbit 40152 km away from us and is inclined by 51 degrees. This follows an apparent anomaly that is affected after the launch of the satellite.
China Academy of Space Center is planning more than 40 satellite launches by the end of this year, followed by the 48 long march lanches that happened last year.
Out of all the missions happening this year, the main eye will be on the six launches that will complete the country’s three-modulemodules, a T shape Tiangong space station.
Including this mission, long March 2D is scheduled to launch more than 15 times in 2022, the rocket will also launch the more three rockets of Chinese launch satellite that are Jiuquan, Taiwan and Xichang.
Shiyan satellite has always been one of the best satellite that China has ever produced, and all the ten Shiyan’s have done a great job in the past and are continuing what they were made for.
China, as mentioned above, is planning more than 40 satellites to launch this year, I am quite excited to watch their success and growth in this industry.
