  And now the question is, are the satellites really related to the HOTS mission, or is this something else?
  

  It could be a replacement of the failed Shiyan 9 mission.
  
  Chinese GSSAP sounds logical.
  

  Shiyan 9 mission failed ?
  

  That is my guess.
  The satellite is currently still in 502x35790 km orbit.
  

  Shiyan-9 is mainly used for in-orbit verification tests of new technologies such as space environmental monitoring.

• According to this commemorative cover both payloads were named Shijian-17-02 and Shijian-17-03 before launch.
  
  HAPPY NEW YEAR to all.

  Before Jan 7, the distance was the same.
