Title: Innovations of Carl H Hubert
Introduction
Carl H Hubert is a notable inventor based in East Windsor, NJ, with a remarkable portfolio of 8 patents. His work primarily focuses on advancements in spacecraft technology, particularly in attitude control systems and thruster operations.
Latest Patents
One of his latest patents is titled "Attitude control by modulating the rate of propellant depletion." This invention involves a spacecraft that includes a pair of propellant tanks, strategically positioned to optimize the center of mass. The system utilizes a controllable coupling arrangement to manage propellant flow to a thruster, addressing unwanted torques that may disrupt the spacecraft's attitude. The attitude control arrangement generates an error signal to correct deviations from the desired orientation, allowing for precise control of the propellant usage.
Another significant patent is "Spacecraft thruster operation for improved orbital maneuver accuracy." This invention describes a spacecraft equipped with an attitude control system that generates signals representing deviations from the desired attitude. The thrusters are arranged in pairs to produce opposing torques, and a velocity change controller generates firing command signals to achieve desired velocity changes. The thruster control system allows for differential firing of the thrusters, enabling effective attitude control while maintaining consistent total firing time.
