    Following separation of the third stage and the primary Deep Space 1 payload, the Delta second stage manoeuvred from its 185 km parking orbit to a 174 km x 2744 km x 28.5 degree orbit. It then released the SEDSAT micro-satellite, built by the Huntsville, Alabama chapter of SEDS (the Students for the Exploration and Development of Space). SEDSAT has two amateur radio transponders and an earth imaging camera.
