This spacecraft is a small secondary payload carried on the Pegasus launch. It is a pathfinder to demonstrate two-way communications for a global network for the Orbital Communications Corporation (Orbcomm). Orbcomm is a wholly-owned subsidiary of Orbital Science Corp., the manufacturer of the Pegasus launch vehicle. It carried an experimental payload to determine global VHF frequency utilization prior to the launch of ORBCOMM constellation satellites. It measured user density, power levels and interference worldwide. OPX featured integral solar panels and antennas, and a passive attitude control system. It formed the basis of the OSC pico-star bus.
