OTS-2, ESA's Orbital Test Satellite launched in May 1978, was placed into a graveyard orbit approximately 320 km above geosynchronous height during the first week of January 1991. After reorbiting, extensive end of life tests relating to the dynamics of the spacecraft were performed. Various nutation control strategies at intermediate and large nutation angles were investigated before placing the spacecraft into a flat spin condition.
