Abstract

Conventional satellites are costly and unreliable. We propose a pico-satellite formation as a virtual phased array to reduce costs and improve reliability. A low-power FDD transceiver wirelessly receives an LO signal from a gateway, eliminating power-hungry PLLs. Precise beamforming is achieved by calibrating path differences and using SRFA technology. This work enables future low-cost, highly reliable satellite communications.
