Title: Jeffery D Stoen: Innovator in Spacecraft Reorientation Technologies
Introduction
Jeffery D Stoen is a notable inventor based in Palo Alto, CA (US). He has made significant contributions to the field of spacecraft technology, holding a total of 3 patents. His work focuses on innovative methods for spacecraft reorientation, which are crucial for space exploration and satellite operations.
Latest Patents
One of his latest patents is a method to reorient a spacecraft using only initial single axis attitude. This method involves inertially aligning a spacecraft along an axis by utilizing quaternion feedback control for reorientation. During the reorientation process, rate integrating gyroscopes are employed in a pulse rebalance loop. The method operates by first using a sensor to provide an initial fix on the inertial direction of interest. It then repetitively determines the difference between a commanded quaternion and a quaternion estimated based on sensed angular rates. Selective application of torques to the spacecraft drives this difference towards zero, aligning the spacecraft vector with the inertial direction of interest. The method includes modes of operation that either maintain the spacecraft's fixed orientation or rotate it about the direction of interest using a bias-rate blind quaternion propagation technique.
