Optimization system for managing satellite constellation
A recently granted patent (Publication Number: US11958634B2) discloses an optimization system designed to manage a constellation of satellites efficiently. The system comprises three main components: a constellation configuration system, a constellation planning system, and a node planning system. The constellation configuration system receives mission objectives from users and instructs satellites to allocate resources accordingly. The constellation planning system resolves contentions, optimizes resource usage, schedules communications, and manages cross-link communications between satellites. The node planning system ensures the safety of satellite assets, autonomously tasks satellites based on plans, and intervenes when necessary. Additionally, an asset profiling system evaluates the system's performance against observed data to optimize efficiency.
Furthermore, the patent details a method for planning tasks for a constellation of satellites. The method involves receiving requests from clients to create planning tasks, generating progress statuses, and returning them to clients. It includes steps to validate requests, delete tasks, handle errors, determine contact assignments between satellites and ground stations, perform semi-continuous splitting for scheduling, and manage payload scheduling. The method also involves converting areas of interest into coverage points, executing payload windows when satellites pass over these areas, and splitting payload windows if necessary. Successful task planning results in the transmission of schedules to clients for publication to the satellite constellation, ensuring effective management and operation of the satellite network.
