Abstract: Generally, this disclosure provides systems and methods for solar communication and defense networks. A system may comprise a sun and a plurality of celestial bodies; a plurality of mutual orbits of the sun and celestial bodies; and a plurality of spacecraft each of which comprises at least a transmitter, a receiver, an antenna, a sensing device that is capable of monitoring and detecting space objects, a system that is able to adjust the orbit, and a system that is able to intercept space objects.

Abstract: A system for distributed phased array multiple input multiple output (DPA-MIMO) communications is disclosed. The system includes beamforming (BF) modules. Each BF module comprises a beamforming antenna, a downconverter that downconverts a beamformed antenna radio frequency signal to an intermediate frequency signal, and an upconverter that upconverts an intermediate frequency signal to a radio frequency signal and sends said radio frequency signal to said beamforming antenna for transmission. The system further includes intermediate frequency (IF) radios. Each IF radio comprises a downconverter that downconverts an intermediate frequency signal sent from a BF module to a baseband signal, and an upconverter that upconverts said baseband signal to an intermediate frequency signal that is transmitted to a beamforming module.

Abstract: Generally, this disclosure provides practical systems and methods for distributed phased array multiple input multiple output (DPA-MIMO) communications.
