Adapting a Ground-Based Laser Ranging System at NASA-GSFC for Identification and Tracking of Orbital Debris

The mitigation of orbital debris was addressed in the most recent release of the National Space Policy directing space faring agencies to pursue technologies that will "mitigate and remove on-orbit debris." No matter what abatement technology is developed and deployed, still lacking is the remote sensing infrastructure to locate and track these objects with adequate precision. We propose using GSFC's ground-based laser ranging facility to provide meter-level or better ranging precision on optically passive 10-30 cm orbital debris targets with the goal of improving current predictions up to 85%. The improved location accuracy also has the immediate benefit of reducing costly false alarms in collision predictions for existing assets.
