Program: AMPTE
Active Magnetospheric Particle Tracer Explorers
International scientific program; composed of 3 small satellites launched
together in geostationary transfer orbit. CCE separated and fired its Star 13
rocket to move to a lower inclination orbit. The IRM satellite then fired its
Hercules BE-3 motor to raise its apogee to more than 100 000 km. Finally the
British UKS satellite separated from IRM (UKS didn't have propulsion of its
own).
