This project was revealed to the public on 2nd April this year. They now claim that they are making progresses toward finding gravitational waves.

China's Tianqin satellite project has made breakthroughs in the key technologies to detect gravitational waves, the project's leader told a space science conference in Guangzhou.

In-orbit verification can start as progress has been made on inertial sensing, laser interferometry, the drag-free control system and satellite platform, Luo Jun, a physicist at the Chinese Academy of Sciences, also leader of Tianqin projetc, was quoted by the Xinhua News Agency as saying at a symposium of the Xiangshan Science Conference.

Three high-orbit satellites were launched at the end of September, Luo said.

He noted that the four-phase 15 billion yuan ($2.3 billion) project, launched in 2015, should be ready to gauge waves by 2030.
