Preventive Maintenance on Space Systems.
Abstract
With the advent of an operational Space Transportation System, many opportunities for activities in space exist. Maintenance of on-orbit satellite systems is one such application. Planners need techniques to evaluate the appropriate maintenance category; i.e., whether a preventive maintenance program is feasible or should a corrective maintenance scheme be applied. This study demonstrates a simple yet technically accurate graphical estimating methodology, known as the Total-Time-on-Test plot. Specifically, using this technique in conjunction with on-orbit life data from Traveling Wave Tube Assemblies located aboard second generation Defense Satellite Communications System (DSCS-II) and North Atlantic Treaty Organization Phase III (NATO III) satellites, preventive maintenance on these items is shown not to be the method of choice. Further, techniques are demonstrated for determining estimated optimal maintenance intervals using failure and repair costs should preventive maintenance be demonstrated as a feasible maintenance category.
