Title: Walter Fichter: Innovator in Spacecraft Control Systems
Introduction
Walter Fichter is a notable inventor based in Munich, Germany. He has made significant contributions to the field of spacecraft control systems, holding a total of seven patents. His work focuses on innovative methods for controlling the attitude of spacecraft, which is crucial for their operation in orbit.
Latest Patents
Fichter's latest patents include a method for controlling the attitude of a three-axis stabilized, Earth-oriented bias momentum spacecraft. This invention addresses the challenge of controlling spacecraft with only two-axis attitude measurements from Earth sensors. Unlike traditional spacecraft that rely on a fixed orbital Earth pointing reference frame, his design considers time-varying reference signals, making it a tracking problem. The controller design incorporates a decoupling controller and axis-related PID controllers based on yaw observer estimates.
Another significant patent is a system for the autonomous on-board determination of the position of an Earth-orbiting satellite. This system utilizes a biaxially measuring Earth sensor to define the yaw axis of the satellite, along with several biaxially measuring sun sensor measuring heads. These components work together to provide direction vector measurements, even during Earth shadow phases. The system accounts for out-of-plane movement and compensates for sensor uncertainties and thermal deformations through precise modeling and regular calibration.
Career Highlights
Throughout his career, Walter Fichter has worked with prominent companies in the aerospace sector, including Daimler-Benz Aerospace AG and Deutsche Aerospace AG. His experience in these organizations has allowed him to develop and refine his innovative ideas in spacecraft technology.
