  • Patent number: 11881927
    Abstract: 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.

  • Patent number: 11507905
    Abstract: Systems and methods are provided for scheduling objects having pair-wise and cumulative constraints. The systems and methods presented can utilize a directed acyclic graph to increase or maximize a utilization function. The objects can comprise satellites in a constellation of satellites. In some implementations, the satellites are imaging satellites, and the systems and methods for scheduling can use human collaboration to determine events of interest for acquisition of images. In some implementations, dominant edges are removed from the directed acyclic graph. In some implementations, dynamic weights are assigned to nodes associated with downlink events in the directed acyclic graph.

  • Patent number: 11388359
    Abstract: Systems and methods in accordance with embodiments of the invention implement TDI imaging techniques in conjunction with monolithic CCD image sensors having multiple distinct imaging regions, where TDI imaging techniques can be separately implemented with respect to each distinct imaging region. In many embodiments, the distinct imaging regions are defined by color filters or color filter patterns (e.g. a Bayer filter pattern); and data from the distinct imaging regions can be read out concurrently (or else sequentially and/or nearly concurrently). A camera system can include: a CCD image sensor including a plurality of pixels that define at least two distinct imaging regions, where pixels within each imaging region operate in unison to image a scene differently than at least one other distinct imaging region. In addition, the camera system is operable in a time-delay integration mode whereby time delay-integration imaging techniques are imposed with respect to each distinct imaging region.
