Title: Subhash C Garg: Innovator in Spacecraft Attitude Control
Introduction
Subhash C Garg is a notable inventor based in San Jose, CA, who has made significant contributions to the field of spacecraft attitude control. With a total of 2 patents, Garg's work focuses on innovative methods to enhance the performance and stability of spacecraft during operation.
Latest Patents
Garg's latest patents include a "Transition control system for spacecraft attitude control" and "Spacecraft attitude control using coupled thrusters." The first patent describes a method for controlling the transition from thruster control to momentum wheel control, aiming to minimize nutation angle and transition time in a three-axis stabilized spacecraft. This method utilizes real-time measurements of momentum components and angular rates, generating paired roll and yaw thrust impulses to achieve a state of substantially zero nutation. The controller employs a deadbeat principle in a closed-loop real-time feedback system, ensuring efficient control with minimal transient overshoot.
The second patent presents an attitude control system for a three-axis controlled spacecraft, addressing the challenges posed by significant cross-coupling torques. A thruster command conditioning electronics module (TCCEM) is introduced to convert torque requirement signals into scalar quantities for thruster modulation. This innovation allows for precise attitude adjustments despite the presence of cross-coupling, enhancing the overall control of the spacecraft.
