OSETS stands for Orbtal Solar Energy Transfer Satellite, which is one of the many solar heat collectors used to focus sunlight onto the surface of Coruscant. These collectors provide heat to the moderately cold world, and also serve to melt the polar icecaps for water. OSETS 2711 was commandeered by Rogue Sqaudron and Winter, as part of their last-minute plans to knock out the planet's shields in preparation for a New Republic assault. They caused OSETS 2711 to heat a water resevoir to boiling, creating a huge series of thunderstorms that knocked out the planet's computer systems, bringing the shields down. OSETS 2711 was under the command of Virar Needa at the time.
