| Abstract |
Handling water make thermal drills rather tricky to use. People obtaining such a drill in very cold ice face with two main problems:
In order to improve reliability of our 4000 meters thermal drill, researches have been carried on about specific telemetering and remote control electronic circuits. Purpose of this paper is to give a few informations about two tests systems designed in order to compare reliability, efficiency, implementation and use of two transmissions principles, one using a frequency division multiplexing and the other a time division multiplexing principles. A third final system should be designed after the first field tests taking very likely into account both transmission principles. |
