Microwave Power Transmission Studies Vol4 of 4

Radio frequency and bandwidth allocation is normally a long process involving national & international technology and socio-economic considerations. It will take 2 to 4 years of DC-RF converters' and filters' technology development to mature the concept and make available meaningful data. Convincing the national & international community involved that gigawatts of power beamed from space at an allocated frequency with a specified narrow bandwidth will not in fact result in significant interference requires a positive approach that is yet to be defined. When it is shown convincingly that power from space would (a) be a significant answer to the national and international future power needs, and (b) permit frequency allocation and bandwidth to be defined without significant interference outside the band; then securing high priority for frequency allocation will be a normal process. The appropriate risk rating is 4-. Support modules for orbital assembly have been defined as life support modules from which required on-orbit manned operations would be conducted. The general strategy for orbital assembly derives in large part from the strategy for maintenance & operations which are monitoring, adjusting, disassembling and assembling types of activities. Operations & maintenance is also by definition in geosynchronous orbit and will be planned as a set of remotely controlled operations. The maintenance equipment itself, such as remote manipulators, jigs, rigs & tools, will be more complex & prone to malfunction than the primary operational equipment. Support modules then might be (a) living quarters, (b) monitoring command & control station, and (c) maintenance repair & storage hangar. In the commercial operational time period the on orbit manned participation should be planned to be minimal. However, full hardware & transportation provisions should be maintained available to support on orbit manned participation as contingencies arise. Support modules for orbital assembly will be used primarily in low orbit
