Attitude Control

Abstract

A Small Business Innovation Research (SBIR) contract to ITHACO, Inc. satisfied a Goddard Space Flight Center demand for a low cost altitude control system for small spacecraft. The SBIR-sponsored work resulted in the T-Wheel, built specifically for altitude control of small and medium-sized spacecraft. Another product, the T-SCANWHEEL, reduces overall system cost, minimizes mass and power and enhances reliability with a mixture of altitude control and control capacity. Additionally, the Type E Wheel is built for use on medium to large spacecraft. Through July 1996, ITHACO had delivered or was under contract for 95 T-Wheel, T-SCANWHEEL, and Type E Wheel units.
