RADIO WAVES AND IONOSPHERE
Scientists Learning From Satellites
(New Zealand Press Association) WELLINGTON. Nov. 13. Scientists have learned a lot from the Soviet earth satellites, even though the Russians are not telling them much, said Mr K. J. Salmon, a Civil Aviation Admin- ( istration engineer, who has just ! spent two months in the United States. Canada, and the Arctic, before taking over control of the Combined American-New Zealand I.G.Y. station at Cape Hallett. , The Central Radio Propagation Laboratory at Boulder, Colo- : rado, was getting valuable infor- . mation from Sputnik 1 by study- j ing the different transit times of - radio waves through the ; ionosphere on the two frequencies • of the satellite, he said. An idea of the thickness and general conditions of the ionosphere was obtained, as transit times through ‘ the ionosphere are determined by the frequency. The transmitter in the ionosphere was, of course, the first one ever to operate outside the ionosphere.
