GIOVE laser ranging processing
As part of the support to the Galileo project, the Navigation Support Office provides orbit predictions of the GIOVE satellites to the International Laser Ranging Service (ILRS) so that the laser stations can track the GIOVE satellites. To this end, laser measurements are retrieved from the ILRS network and processed with a routine orbit determination system based on NAPEOS. The resulting orbit predictions are submitted back to the ILRS. Whenever one of the satellites is manoeuvred, ILRS is informed timely to take this event into account in the tracking schedule of the laser stations.
