Doris-equiped satellites
The Doris system has been a great technical, operational and scientific success. The Doris instrument, which is already flying on a number of satellites and is being considered for several new missions, guarantees users a high-quality operational service providing precise orbit determination over the long term. With more satellites carrying the Doris instrument, the system will make more accurate than before.
