The Galileo in orbit verification (IOV) program, consisting of 4 spacecrafts, is the first step towards an European satellite-based navigation system. The main objective of the IOV phase is to verify the proper functioning of the overall system before starting the next step - Galileo full operational capability (FOC) - where the full deployment of 30 Galileo satellites will be performed. This paper gives an overview of the Galileo IOV attitude and orbit control (AOC) function with the focus being put on the spacecraft attitude control. The AOC is a part of the avionics subsystem, manufacturing of which has been subcontracted to Astrium. The article also describes the overall requirements on the control system, the AOC hardware and operational architecture as well as selected details on the AOC algorithms with corresponding test results.
