A solid-propellant apogee boost motor was developed for the geostationary scientific satellite GEOS. It forms an integral part of the satellite and is used to inject it into geostationary orbit from the initial elliptical transfer orbit provided by the Thor-Delta launch vehicle. The motor's design, development, and qualification program, and ground test firings in air and in vacuum are described. The 306 kg GEOS motor produces 23,000 Newtons of thrust and accounts for more than half the satellite's total weight.
