China successfully launched two test satellites from a launch platform in the Yellow Sea on October 7.

The CentiSpace-S5/S6 test satellites with LEO satellite navigation enhancement system were lifted off by a Long March-11 carrier rocket at 09:10 p.m. (Beijing Time) and they have entered the planned orbit successfully.

The satellites will be used to monitor the performance of the global navigation satellite system in real time, and carry out navigation augmentation and intersatellite laser communication tests.

It was the 441st flight mission of the Long March series rockets.
