that did not undergo modifications remained in full-force for the affected States. The 1959 Radio Regulations gave very little attention to the space radio frequencies that might be registered with the IFRB. It did begin the process of identifying systems in which space objects could participate, and it did begin to define a variety of space-connected subjects. Thus, in 1959 a definition was established for a "Space Service," for an "Earth-Space Service," and for a "Space Station." In 1959 the first allocation of frequencies for space use was made to Region 2. The allocation was made for "research purposes"?? under the classifications of "space" and "earth-space." By 1971 the definition of a "space service" had been deleted and a new definition had been given to "space station," namely, "A station located on an object which is beyond, is intended to go beyond, or has been beyond, the major portion of the Earth's atmosphere." In 1971 a "Space System" was defined as "Any group of co-operating earth and/or space stations employing space radiocommunication for specific purposes." The identification of services has been expanded with the "Meteorological - Satellite Service" emerging from the 1963 conference. In 1971, the 12 UST 2377, 2450, TIAS 4893. Ibid., p. 2449. Allocations were made in the ranges of 108-144 Mc/s, 235-401 Mc/s, 1,350-1,535 Mc/s, 1,700-1,710 Mc/s, 2,290-2,300 Mc/s, 5,250-5,255 Mc/s, 15.15-15.25 Gc/s, and 24.25-40 Gc/s. Ibid., pp. 2449-2478. The foregoing frequencies were variously allocated in all three regions. None were allocated at the GHz level. 23 UST 1527, 1571, TIAS 7435. 23 UST 1527, 1569, TIAS 7435.
