LEOP (Launch and Early Operations Phase) support for two three axis stabilized spacecraft which use very different attitude control systems is addressed. Olympus was launched in Jul. 1989 and Italsat in Jan. 1991. The Olympus and Italsat onboard attitude and orbit control systems are outlined with emphasis on the transfer orbit phase. The ground control systems for both spacecraft are described with a review of the actual operational experience. The different role of the ground control systems are detailed, and the advantages and disadvantages of both systems analyzed. Future trends in the design of the ground control systems are discussed.
