Description
Recent activity in the MILSATCOM architecture arena has resulted in extensive assessment of potential satellite resources. Government and industry participants, striving for continuous, economical and effective communications assets through the rest of the century, have directed attention toward upgrading existing systems as well as defining and initiating new system* developments. An example of the more cost efficient approach presently being considered by the government is future upgrades of the DSCS III satellites which are currently under development/production at GE's Space Systems Division in Vally Forge, PA.
Based on Air Force funded product improvement studies and GE internal initiatives to improve the DSCS III spacecraft, the feasibility of growth to a larger, higher power consumption payload has been analyzed. The DSCS III bus can accommodate these changes without major structural design impact. As summarized in this paper, the upgrade accommodations can be achieved with available technology and only partial subsystem redesign efforts. Product improvements for near term performance enhancements will only require requalification at the component and subsystem levels. Not until later updates are the performance requirements enough to demand a requallfication at the system level and, at that, a majority of the system design is still unchanged from previously qualified/flown configurations.
