[Saral/AltiKa] News about maneuvers and station keeping

Category: Operational news

The last maneuver could not be carried out. See impacts.

The last maneuver (OM #45) could not be carried out as reaction wheel was stuck at 0 rpm during reorientation. There was no thruster firing as OM was aborted before the burn start. Though the satellite has been normalized to geodetic pointing, kindly note that the next OM will be planned after thorough discussion with designers. There is no mispointing problem.

As a conclusion, the ground track will not be maintained between +/- 1km from the theoretical ground track for the moment.
