China's most advanced satellite platform successfully enters orbit

China’s most advanced satellite platform successfully enters orbit after being launched by the ‘world’s most powerful rocket’ as part of Beijing’s Mars mission in 2020

  • China’s DFH-5 platform will be formed by many satellites in high orbit 
  • Shijian-20 reached its geosynchronous orbit above China on Sunday  
  • It will eventually have a wide range of purposes, including communications, remote sensing and scientific experiments

China’s heaviest satellite – and also its most advanced – has successfully entered into a geosynchronous orbit around Earth.

Geosynchrous orbit is more than 22,000 miles above Earth and allows satellites to stay over the same part of the planet at all times, allowing for 24/7 communication.  

The Shijian-20 satellite reached its far-away spot on Sunday and is the first verification satellite for the Dongfanghong-5 (DFH-5) satellite platform.

It launched on December 27 atop the Long March 5 Y3 rocket, which has accrued the title of the world’s most powerful rocket by Chinese media. 

It will eventually have a wide range of purposes, including communications, remote sensing and scientific experiments, according to the Chinese space agency. 

The satellite, and its complex platform, is expected to be used for future missions to the moon and beyond, including a planned trip to Mars in 2020.

China’s heaviest satellite has successfully enters into a geosynchrous orbit around Earth, a huge step for the country’s space programme. Geosynchrous orbit is more than 22,000 miles above Earth 


A geosynchronous orbit is a high Earth orbit that allows satellites to match Earth’s rotation. 

Satellites in a geosynchrous orbit are more than 22,000 miles (35,000km) above Earth – considerably higher than most satellites. 

Their extreme vantage points affords them the ability to monitor weather, communications and surveillance equipment

it is especially useful for monitoring a single location for a long period of time as it matches Earth’ spin. 

This means over months and years, the satellite will be scrutinising the same region relentlessly. 

The satellite is being hailed as China’s most advanced craft yet by state-run media and weighs a reported eight metric tonnes. 

The Shijian-20 satellite, which translates as ‘Practice’, is designed to be a high-throughput communications satellite ‘capable of delivering 1 Tbps bandwidth for ultrafast speeds,’ Chinese space officials said according to the state-run Xinhua news agency.

It is also believed the satellite will test out a new laser communications system for future missions and ion thruster technology.   

Zhou Zhicheng, chief engineer of the DFH-5 satellite platform, says it is far superior to its predecessors, the DFH-3 and 4. 

Pei Shengwei, deputy chief designer of the Shijian-20 satellite, said: ‘The DFH-3 platform follows the international technology standards while the technology of DFH-4 platform follows and even keeps pace with the international technology in some areas. That means we have reached the same level with others in some technologies.’ 

It is claimed it has improved in weight, power and in-orbit lifespan, which will serve the needs of high-capacity satellites in the next 20 years,  

The success of the Long March 5 launch gets the Chinese space programme back on track after a previous attempt in July 2017 failed mid-launch.

It was a test of ‘key technologies related to future space missions’, according to the China’s National Space Administration.

‘The rocket is tasked with important missions,’ Wu Yanhua, the deputy head of China’s National Space Administration, told CCTV in December. 

‘It will be tasked with a series of key missions including launching China’s first Mars probe, the Chang’e-5 lunar probe and a core module for the manned space station.’ 


Officials from the Chinese space agency have said the country will return to the moon by the end of 2019 with the Chang’e-5 mission.

This will collect rocks from the near side of the moon and return them to Earth for further study. 

Chang’e-6 will be the first mission to explore the south pole of the moon. 

Chang’e-7 will study the land surface, composition, space environment in a comprehensive mission, it was claimed, while Chang’e-8 will focus on technical surface analysis.

China is also reportedly working on building a lunar base using 3D printing technology.  

Mission number eight will likely lay the groundwork for this as it strives to verify the technology earmarked for the project and if it is viable as a scientific base.  

China’s space agency the China National Space Administration (CNSA) also say they want to travel to mars by 2020.
