Reported in this paper is the initial phase operation of the Attitude and Orbit Control System (AOCS) of Japanese satellite 'AKARI (ASTRO-F: Infrared Imaging Satellite)'. AKARI is the first Japanese satellite dedicated to the infrared astronomy. AKARI was successfully launched by M-V rocket from Kagoshima Space center on February 22, 2006. Just after the launch, AKARI faced to a serious problem. It was found that something interferes with the fields of view of two (out of two) sun sensors. The two sensors were out of use in the subsequent AOCS operation. The anomaly prevents us from carrying out the pre-planned initial phase operation, and constrains us to reconfigure the AOCS architecture. The experiences in this recovery operation are mainly reported in the paper. In addition, unexpected continuous orbit rising was observed in the operation. The cause of the phenomenon and its investigation process are also reported.
