New technique makes low-orbit satellite cheaper and simpler to design

Simple shift could make low Earth orbit satellites high capacity

Researchers at Princeton Engineering and at Yang Ming Chiao Tung University in Taiwan have invented a technique that enables low-orbit satellite antennas to manage signals for multiple users at once, drastically reducing needed hardware. The strategy builds on a common technique to strengthen communications by positioning antenna arrays to direct a beam of radio waves precisely where it’s needed.
