A digital payload for processing a sub-band spectrum received on an uplink beam at a communications satellite includes a digital channelizer, a digital switch matrix and a digital combiner. The digital channelizer divides the sub-band spectrum into a plurality of frequency slices that can be routed by the digital switch matrix to any of a number of receiving ports. A digital combiner receives the frequency slices and re-assembles them to form one or more output sub-bands for transmission on an output beam of the communications satellite. The digital payload may also include an embeddable digital regeneration module configured to demodulate some or all of the sub-band spectrum to extract a digital bitstream therefrom. The digital bitstream may be processed to implement code-based multiplexing, switching, access control, and other features.

Systems and methods for digital processing of satellite communications data

A system and method for enabling on-demand inter-spacecraft resource sharing and coordination are disclosed involving at least one wireless device and a payload. At least one wireless device transmits and receives communications to at least one access point and at least one user. In one or more embodiments, spacecrafts are employed for the access points and/or the users. The payload comprises at least one transponder and at least one processor. At least one transponder transmits and receives the communications to at least one access point and at least one user. The processor provides channelized communication and regenerative communication to at least one user. Also, the processor monitors signal quality of the communications received from at least one user. In one or more embodiments, the wireless device is a radio frequency (RF) omni-directional antenna. In some embodiments, the wireless device is a diffuse optical emitter and receiver.
