Title: The Innovations of Robert W. Astheimer

Introduction

Robert W. Astheimer is an accomplished inventor based in Fairfield, CT (US). He is known for his significant contributions to the field of spacecraft technology, particularly in the development of sun sensors. His innovative approach has led to advancements that enhance the accuracy of attitude determination for spacecraft.

Latest Patents

Astheimer holds a patent for a method that greatly increases the ratio of direct sunlight to earthshine in a sun sensor used on spacecraft. This invention is crucial for spacecraft that orbit the Earth, as it allows for more precise orientation with respect to the sun-illuminated Earth. The sun sensor features a detector that restricts incoming radiation to a spectral region where the Earth's atmosphere is highly absorbent. This ensures that the detector only receives radiation directly from the sun, while reflected light from the Earth is absorbed by the atmosphere, preventing it from reaching the detector. One suitable spectral region identified for this application is the ultraviolet absorption band from 200-290 nm, utilizing a UV-enhanced silicon detector.
