 Another example is when geostationary communications satellites reach the end of their useful lives.Stewardship cessation will occur hopefully in a planned manner, where the operator will move the satellite to a somewhat higher orbit to minimise the risk that the satellite will be a collision hazard to other satellites in the geostationary arc (graveyard burn).Unplanned stewardship cessation will occur if telecommand access to the satellite's systems is cut off due to a failure, for instance in the telecommand receivers.
