Title: Cheng A Wu and His GPS Antenna Patents.

Introduction

Cheng A Wu is an inventor based in Woodland Hills, California. His work includes inventions for using GPS signals to determine the spin rate and orientation of orbiting spacecraft. He is associated with The Aerospace Corporation and is credited with 2 patents.

Latest Patents

Wu’s listed patents address a GPS patch antenna attitude reference system and a related method.

The system patent describes using a pair of patch antennas to create a null-slit antenna pattern. The pattern receives signals from at least three GPS satellites, which serve as “pseudo stars” for determining the spin rate and spin-axis attitude of a spinning spacecraft in an Earth orbit below the satellites.

The method patent describes using a null-slit antenna pattern to receive signals from at least three GPS satellites and determine the spin rate and spin-axis attitude of a spinning spacecraft. Together, the inventions apply GPS reception to spacecraft attitude reference and motion measurement.
