Title: Rocketed data communication system

Abstract: A system for retrieving at a given station, either on the ground or in the ir, data from a site on the earth's surface from which ground-based communication would be impracticable, either because of configuration of terrain or of the existence of intervening natural or man-made obstacles, wherein an assembly comprising a rocket module and a surface module connected together by an umbilical connector is emplaced directly or by air drop at the site and wherein the data is acquired at the site by sensors located within the surface module and recorded by a recorder located within the rocket module. Upon command from the given station, or after a predetermined time set by an electronic clock, the rocket module is launched into near space, and, upon attainment of an altitude at which suitable line-of-sight transmission of energy can be accomplished, a transmitter in the rocket module connected to the recorder is actuated, permitting the recorded data retrieved from the surface to be transmitted from the rocket module to the aforesaid station.
