Paper Abstract

The OrbitalManeuveringVehicle(OMV) is an unmanned spacecraft which is scheduled tobe deployed in the early 1990's by NASA. Its purpose is to relocate satellites and other orbiting objects in space, e.g., to reboost large observatories as their orbits gradually decay. The OMV Video System (VS) was designed to be used for remote-controlled docking with an orbiting object. The final approach and rendezvous with the OMV will be controlled by a ground-based pilot. The OMVVS captures 5framesofvideo data per second and compresses the data in eachvideo frameby approximately 5.5to1 using a spatial resolution reduction scheme and a multi-mode intraframe coding scheme. The OMV VS is crucial to a successful mission. The image quality must be sufficient for the pilot to precisely locate the target object. The quantity of transmitted data (video and error correcting codes) must be limited due to communication channel constraints. The compression hardware is constrained by power and heat dissipation limitations on the OMV The existing system and some possible Improvements will be described.
