Title: John A. Lehner: Innovator in Satellite Technology
Introduction
John A. Lehner is a notable inventor based in Sunnyvale, CA, with a focus on advancements in satellite technology. He holds a total of 3 patents, showcasing his contributions to the field. His innovative work has significantly impacted how satellites operate and maintain stability in orbit.
Latest Patents
One of Lehner's latest patents is a satellite stabilization system. This system compensates for destabilizing torque introduced by solar radiation pressure through the use of tabs of material angled relative to the back surfaces of antenna reflectors. These tabs intercept solar rays, allowing for a more balanced torque around the satellite's axis. Each tab is designed as a plate or disk, attached via a spring mount to the back surface of the reflectors. The angulation of the reflectors and tabs helps equalize the torque from solar radiation pressure, enhancing the satellite's stability.
Another significant invention by Lehner is a method and apparatus for inclined orbit attitude control for momentum. This invention provides a way to control the pointing trajectory of an aim point concerning one or more targets for a momentum bias spacecraft in an inclined orbit. The onboard computer utilizes available orbit information to adjust the aim point according to a predetermined tracking model, effectively managing short-term and long-term dynamical disturbances.
