Don't know what else EGP has on it, but if it's an uncontrolled
sphere studded with corner cube reflectors and nothing else, then its
primary purpose is to act as a reflector for laser ranging. There are
a few dozen of these sites around the world, using satellites like
EGP and others (e.g. ERS-1, fitted with a few reflectors on the 
side. The data's used for research into the upper atmosphere, tectonic 
shift, etc.
