- Abstract
The mission requirements for an imaging satellite are having higher camera capability, shorter revisit cycle, larger coverage area, less orbit maintenance, and more available launch vehicles. The driving factors are resolution, revisit cycle, field of regard, propellant, and total weight. For international cooperation to develop satellites, there are various scenarios for the roles and responsibilities, including breakdown in systems, components, manpower, cost, or schedule. For distribution of the images, there are different manners like direct receiving, virtual reception, or product delivery. Since small satellites are limited with its size, power, maneuverability, and propellant, the difficulties can be overcome by utilizing time delay and integration, line-of-site pointing, and constellation. A procedure to optimize the cost-effective imaging satellite constellation is proposed in this paper, which aims to achieve daily revisit and global coverage for all the participants from commercial or government sectors under constraints of geographical coverage, budget limitation, and application fields.
