Patent number: 11881927Abstract: Systems and methods for controlling satellites are provided. In one example embodiment, a computing system can obtain a request for image data. The request can be associated with a priority for acquiring the image data. The computing system can determine an availability of a plurality of satellites to acquire the image data based at least in part on the request. The computing system can select from among a plurality of communication pathways to transmit an image acquisition command to a satellite based at least in part on the request priority. The plurality of communication pathways can include a communication pathway via which the image acquisition command is indirectly communicated to the satellite via a geostationary satellite. The computing system can send the image acquisition command to the selected satellite via the selected communication pathway. Data from the satellite can be relayed to ground-based stations via one or more relay satellites.Type: GrantFiled: October 3, 2022Date of Patent: January 23, 2024Assignee: PLANET LABS PBCInventor: Kiruthika Devaraj
