A Long March 4C (CZ-4C) rocket successfully launched the Yaogan 33R (aka Yaogan 33-02) radar/remote sensing satellite at 1544 GMT on 27 December 2020.  The spacecraft was thought to be a replacement for the Yaogan 33 lost in a launch failure in 2019. However this is now thought to be a different design of radar satellite. The launch put the SAST-built spacecraft into a 686 x 682 km orbit at 98.3 degrees inclination sun-synchronous low Earth orbit. Also aboard the launch was the WJS-1 (Weina Jishu Shiyan Weixing-1 (WJS-1) meaning “technology test nanosat”. This launch was China’s final launch attempt for 2020.
