Tactical, real-time space surveillance using multiple, "disposable" satellites

The approach to a LOD, tactical satellite architecture relies on using small agile, launch platforms to rapidly deploy many small satellites to do the job of one large space asset. This requires a change in philosophy from performing missions with single, large, highly reliable, high priced assets to many, small, low performance, inexpensive assets. In other words, achieving mission success with quantity not quality. The challenge becomes developing a satellite/booster system small enough to launch from an existing military aircraft, at a mission cost less than that for a conventional, large satellite. At first glance, a cost of less than /spl Mscr/ for the booster, satellite, and payload must be realized to make the concept feasible. It is believed these costs are achievable if two philosophies are accepted. Piece part reliability can be relaxed, through the acceptance of mission success through quantity deployment. This will enable the use of commercial parts and reduce costly certification. And, mission designs are kept within the capabilities of a set of core and kit components designed to fit within the launch platform constraints. This will allow mass production and standardization of interfaces, significantly reducing costs. There are significant technology developments required for satellite/payload component miniaturization, booster size and cost reduction, and automation of the integration, test, and launch process. However there is much work going on the industry in these areas that should continue to be supported.
