Second heaviest GEO satellite launched into space at 7,600 kg
A government satellite, Shijian 20 is operated by China Aerospace Science and Technology Corporation (CASC) of China for the purpose of technology development.
A sun-synchronous GEO satellite, it was launched into space using Long March 5 as the launch vehicle from Wenchang Satellite Launch Center on 27 December 2019. Shijian 20 was constructed by China Aerospace Science and Technology Corp. (CASC) (China).
Designed with an operational lifetime of 20 years, Shijian 20 has a launch mass of 7,600 kg and navigates with the COSPAR ID 2019-097A and NORAD ID 44910.
Taking 1,436 minutes to orbit the Earth, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 35,751km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 35,824km. The eccentricity of the orbit is 8.66E-04 and it orbits along the Earth longitude of 125 degrees.
