These spacecraft are spin-stabilized at about 6rpm spin rate, and have same configuration except, of course, for the differing scientific payloads. To assure the communication link between the spacecraft and the ground station, a high-gain parabolic antenna mechanically despun with respect to the spinning spacecraft, is used. In order to provide SUISEI with the ability for ultraviolet imagery of the comet, while satisfying, thermal constraints of the onboard instruments, the spacecraft were also designed so that their spin-rate could be reduced to a low and stable value of around 0.2rpm by spinning up a momentum wheel. The imagery instrument uses the time-delay-and-integration scheme of a 2-dimensional charge coupled device sensor to obtain unblurred pictures of the comet at this spacecraft spin rate. For attitude and orbit control actuator, a hydrazine (N_2H_4) monopropellant propulsion system was developed. Attitude sensors consist of a spin-type sun sensor and a star scanner. Thus far, the attitude and orbit cotrol systems have functioned properly so these spacecraft should be able to fully complete their mission goals. In this report, the function and the detailed design of the attitude and orbit control system of SAKIGAKE and SUISEI are described, together with the analyses pertinent to the design and the operation. The flight results to verify the design are also presented., 資料番号: SA0166130000}, pages = {1--62}, title = {"さきがけ(1985-001-A)" および "すいせい(1985-073-A)" の姿勢・軌道制御系の設計}, volume = {37}, year = {1986} }
