Are they using WGS84?
XI'AN, Aug. 17 (Xinhua) -- Chinese researchers have successfully completed the first test of the propulsion system for the experiment module of the country's planned space station.The test consisted of eight procedures that covered all working conditions of an in-orbit experiment module. It also simulated possible errors the module may encounter in space, according to a research institute affiliated with China Aerospace Science and Technology Corporation (CASC).The test proved that the design of the propulsion system was scientific and its parameters setting was correct, according to the institute.Two experiment modules of China's planned space station will be sent into space in 2021 and 2022, according to Yang Liwei, director of the China Manned Space Engineering Office and the country's first astronaut.China is accelerating its timetable for a space station, with the core capsule expected to be launched in 2020, said Yang.
BEIJING, Aug. 18 (Xinhua) -- Engineers have successfully tested the propulsion system of China's planned space station lab capsules, a key step in its space station program.Weighing 66 tonnes, the space station will comprise a core module and two lab capsules. The propulsion system will determine whether lab capsules can move in space.Engineers designed 36 engines for the propulsion system with four to adjust the capsules' operation orbit and 32 to adjust flight attitude. Each engine is designed to work for at least 15 years, according to the China Aerospace Science and Technology Corporation (CASC), the main manufacturer of the space station.The engines worked well and passed tests in Shanghai, said the CASC.
It might be interesting to try some comparison with Mir. At 65 tons with three large modules in a T-shape, it will somewhat look like Mir as of 1990. That is - DOS-7 + Kvant-1 + Kvant-2 + Kristall. With Tianzhou playing the role of the FGB tug - and Progress altogether. I'm not surprised either than the annual number of Shenzhou flights surges to 5 a year: that's pretty much Soyuz flight rate since Salyut 6 in 1978, up to the ISS days.

It will be interesting to see what they do with the station...so far a real use for space stations has escaped the US and USSR/Russia...other than just "doing space" it does not seem to be designed for anything in particular...

It's kind of a canard that there is no real use for stations. It might be true that the knowledge might be gained at a cost that some might not consider a good value, but to say no knowledge, no use? Not a very useful post since the truth is different.
Launch date of China's Space Station Telescope slipped from 2022 to 2024. Via @Skywatcher2018 's post relaying a talk at the #IAU2018.
Key technical issues on the Chinese space station have been resolved, 13 flight missions are planned for its creation-the Deputy head of the officeBeijing, September 26 / Xinhua / -- Key technical issues related to the main systems of the Chinese space station have been resolved - 13 flight missions are planned for its creation. This was stated on Wednesday in Beijing, the Deputy head of the office of the manned space program of China Lin Xiqiang.The Chinese space station should be built approximately in 2022. The process includes three stages: testing of key technologies, construction and commissioning of the space station."In particular, during the testing phase is scheduled for 6 missions, including the first flight of the carrier rocket "chanchzhen-5" /Long March-5B/, in the construction phase - 7 missions, including the launches of modules I and II," - said Lin, Sician during the presentation of the achievements of the Program of manned space exploration...
China to conduct large-scale experiments in space station BEIJING, Sept. 26 (Xinhua) -- China will carry out large-scale scientific experiments on space application projects after the completion of China's space station, according to a news briefing on China's space projects Wednesday.China's manned space station is planned to be completed around 2022 and will be in orbit for more than 10 years."After the completion of the space station, space experiments and applications will become the main focus of the project," said Lin Xiqiang, deputy director of the China Manned Space Engineering Office, at the briefing.Lyu Congmin, deputy chief designer of the space station's application system, said the space station will be a platform for more frontier space science experiments and applications."We have planned more than 13 laboratories and experimental platforms in the space station. A large optical telescope will be sent into the same orbit to fly with the station," Lyu said. "We will conduct more than 30 research projects in eight areas, including space astronomy, space life science and biotechnology, microgravity fundamental physics and space materials.""The space station can support space applications in and out of the cabin, and the payload can be adjusted in orbit," said Lin. "I believe the large-scale experiments will bring more important achievements with international influence and application value."
SAMARA, Oct 4 — RIA Novosti. Scientists of the Samara national research University in cooperation with the Beijing Institute of space engineering are developing equipment for joint research on the Chinese space station, the press service of the Samara University said on Thursday...."It is planned that after the tests and relevant improvements, the final versions of scientific devices will be created for joint scientific research on the Chinese space station in 2021 within the framework of the Russian-Chinese project," the press service of Voronov quotes....
