Abstract :
Communication during the re-entry of a space vehicle is a formidable problem because thermally-ionized gas in a shock wave surrounding such a vehicle absorbs the signal over the major portion of the radio spectrum. This paper describes some general features of re-entry communications. The entire electromagnetic spectrum is examined for selection of a suitable signal frequency.
