  • Patent number: 11463162
    Abstract: A scalable signal processing system is disclosed that processes digitized spectrum received from a constellation of satellites (or other sources), extracting multiple digital signals from multiple sources through multiple acquisition sites that is virtualized with high availability. A system of one or more antennas can receive a range of frequencies of raw spectrum covering multiple visible orbit planes, where a single antenna can receive signals from multiple satellite concurrently. This can be particularly useful when establishing a constellation satellites, where a number of satellites can be grouped together within an antenna's field of view. A group of digitizers receive the signals from the antennas and creates raw samples to form a spectrum sample pool. The spectrum sample pool is stored in a raw frame archive, where the digitizers and raw frame archive can be co-located and can also be co-located with one or more of the antennas.
