Abstract : Research effort is described in developing a system capable of measuring atmospheric structural parameters above the 100-km level. The sensors to be employed would be of the ionization gage type. Study indicated that one might have a much more successful experiment if the container housing the sensors could be separated from the rocket, preferably in a degassed condition to minimize background contamination. The general research effort included (1) theoretical study of the general measurement problem; (2) development of suitable sensors; (3) development of associated electronic circuits; (4) development of a high-vacuum system to enable study and calibration of the sensors; and (5) development of the nose-cone system to carry and eject the experiment.
