| Abstract | Exploration of the Universe has been a major goal of mankind since his beginning. Modern technology has allowed today's scientists to extend his observations to the planets and actually measure many of the physical phenomenon. Modern science has launched the instrumentation industry into space made possible by communications from rockets and satellites with aerospace telemetry systems. The development of aerospace telemetry has also opened new communication data links for making measurements in deep boreholes in the earth's crust. However, now a transmission line must be used since high frequency signals will not propagate through this medium. Further restrictions are imposed upon well logging transmission liens in high temperature boreholes. It is possible to extend the bandwidth and number of data channels to enhance measurements in geothermal boreholes by combining aerospace telemetry techniques with thermal protection systems and careful selection of wire line data transmission configurations. |
