Peterson AFB in America informed us that they have incorrectly labeled Sumbandila as Fregat-IRIS. They are part of the radar tracking network responsible for uniquely identifying over 20,000 objects in Earth orbit! We have therefore up to now tracked the Fregat-Iris (35867) in stead of Sumbandila (35870).
After correcting the TLE information, our communication with the satellite is more consistent and reliable.
We intend to affect the improvements that we made to our ground station equipment, to the SAC ground station in the coming week.
