Abstract:

The report was prepared to promote mutual understanding between professional disciplines involved in the use of the research vehicles. In order to achieve this understanding, the major problems with some possible solutions are presented. The problems and solutions presented are approached with a 100 percent telemetry data acquisition probability philosophy. Two basic problems evolving from the shift from VHF to S-band are shadowing and interference effects, which appear when vehicle wavelength-to-diameter ratios are less than one. Besides these two, other problems arise which increase the difficulty of developing suitable antenna designs. These include the electromagnetic properties of antennas, vehicle geometric shapes, antenna-vehicle integration, vehicle trajectories and overall telemetry system performance. Some conceptual antenna system designs have been proposed and investigated. Two of these systems have proven feasible, a nose-tip mounted system and a cavity mounted system. However, the two systems designs will not solve all the problems in achieving suitable radiation patterns for all vehicle mission requirements. Since development of S-Band antennas for all aspects of vehicle telemetry use is a relatively recent task, many of the problems are being encountered for the first time, and therefore do not have ready and economical solutions.
