Chine's Secret Computer System

Whether it is China’s rover on Mars, its space station orbiting the Earth or its moon probe bringing back lunar samples, one little-known system is behind them all.  The core of the Kylin computer operating system has been guarded as a national secret and its use in the country’s space programme has only just been officially confirmed.

Its main codes were written by Chinese military researchers, according to developer China Electronics Corporation (CEC), but it also includes elements of Unix-like software FreeBSD, parts from Linux, and a user interface similar to Windows.  It is a hybrid, like the mythical qilin dragon beast it is named after.

Speaking to state media on the weekend, members of the Kylin development team revealed the role the operating system played in these missions, coordinating communication between artificial intelligence software, human controllers on the ground and all the hardware on board the spacecraft.

Until about a decade ago, China, like most other countries, relied on Linux and Windows to drive its space programmes, according to a paper published in domestic journal Space Industry Management last year.

From 2008, China’s space authorities started to replace Western software and hardware in satellites and spacecraft. The process sped up after Edward Snowden’s revelations in 2013 about US hacking activities.

Kylin was one of the results – along with the Zhanxing, or Warring Star, system developed by the Chinese military’s space force, according to the paper.

Dan Jianqun, a lead scientist with CEC’s Kylin project, said China had no other choice but to develop its operating system.

“Using other people’s systems, to quote President Xi [Jinping], is like building a house on other people’s land. It can be large and beautiful, but it can also be destroyed overnight,” he said in an interview on state television on Sunday.

The transition from western to home-made software was full of challenges, according to some of the software engineers involved.  Liu Jun, a software engineer on the Kylin team, said space missions required not only high security, but reliability and performance.  TO READ MORE, CLICK HERE...
