Boosted by its innovation in controlling spacecraft attitude using rotational star trackers, Boeing Satellite Systems (BSS) was able to meet the demanding design requirements for the Spaceway broadband satellite system, which the company is currently building for Hughes Electronics. The BSS-built Spaceway satellites will each feature two star trackers designed to achieve increased pointing accuracy due to an invention covered by a U.S. patent granted recently to three current and one former BSS employees.
