Abstract The ADACS is one of the most expensive subsystems of a spacecraft. Over-specifying ADACS performance requirements can easily “bust the budget.” A common mistake is to call for more stringent accuracy than is required by the payload. For example, if the mission is to simply scan the atmospheric spectrum from the Northern Hemisphere, then pointing much more than 5° is hardly required. Specifying pointing accuracy 1 or 2 orders of magnitude better rapidly leads to expensive equipment, such as star trackers, when a simple momentum-biased system with Earth sensors would suffice.
