Abstract: A high throughput fractionated satellite (HTFS) system and method where the functional capabilities of a conventional monolithic spacecraft are distributed across many small or very small satellites and a central command and relay satellite, the satellites are separated and flight in carefully design formations that allows the creation of very large aperture or apertures in space drastically reducing cost and weight and enabling high throughput capabilities by spatially reuse spectrum.

Abstract: OFDM-BPSK symbol sequences are used for mutual-coupling based phase array calibration. Such substitution allows phase to be estimated more accurately using a given estimation duration without compromising other estimates (amplitude and group delay) accuracies.

Abstract: A base station for communication with a terminal station having a plurality of terminal station antennas. The base station has a plurality of directional antennas, each of the plurality of directional antennas in communication with satellites in view. The base station also has a processing device (e.g., eNodeB) to transmit each of the multiple base-station antenna signals via each of the plurality of directional antennas to satellites and/or the beams of the same satellite seen by the terminal station for retransmission to the plurality of terminal station antennas.

Abstract: A satellite communication system includes a phased antenna array having a field of view (FoV) and configured to communicate with a plurality of cells in the FoV via a plurality of beams. Each of the plurality of beams is associated with one of the plurality of cells. A phased antenna array is configured to apply adaptive taper selection, based on both the satellite position (in relation to a satellite service beam) and its surrounding interference scenario.

Abstract: A ground station processes downlink signals received from respective satellites. The ground station has a plurality of signal conditioning devices each receiving a respective one of the downlink signals and providing a conditioned downlink signal. A plurality of Doppler and/or Delay compensator devices each receive a respective conditioned downlink signal from a respective one of the plurality of signal conditioning devices. The compensator devices conduct Doppler and/or Delay compensation on the received conditioned downlink signal, and provide a compensated downlink signal output. A selector or diversity combiner receives the compensated downlink signal from each of the plurality of Doppler and/or Delay compensators.

Abstract: A phased array has a plurality of antenna element structures each having a planar surface. The antenna element structures are connected to form a structural array with a planar array surface. A processing device generates a beam having a beam phase at the plurality of antenna element structures, monitors and determines in real time for structural displacement of the plurality of structures, determines a correction, and adjusts the beam phase based on the correction.
