The Olympus spacecraft was launched in 1989 with a number of new and interesting features in attitude and orbit control design. The AOCS (Attitude and Orbit Control System) is described and results obtained with the AOCS in transfer orbit are given. The normal and station keeping modes are discussed together with a novel method of performing east-west station keeping developed during the early months of the mission. The results of analysis of the solar array flexible modes using inflight data from an accelerometer package and the gyros is presented, and a comparison of actual sloshing induced momentum and torques with the predicted values from the Olympus AOCS simulator linked to Flow-3d (three dimensional flow software) is given.
