short wave communication by which German forces built-up their long distance communications during World War II.[2]

Biography

After studies of mathematics and physics in

Shortwave communications of the German Luftwaffe, since 1943 for Navy and Army as well.[3]

Rawer's code assumes zig-zag paths between Earth and ionosphere.[4][5] Monthly predictions take account of day-to-day variations.[6] Long term changes from solar cycles is taken account of by Wolfgang Gleißberg´s prediction method.[7]

After the war Yves Rocard, then director of French Navy research, was impressed by Rawer's code. He engaged him as "directeur scientifique" (1946–56) of his newly founded "Service de Prevision Ionospherique".[8]

Between 1956–69, Rawer, serving in Germany as director of "Ionosphären-Institut Breisach" switched to space research. With his team he participated in the first French scientific rocket launch 1954 in the

Sahara desert and later they experimented aboard rockets of different nationality.[9]

From 1958 to 1964, he was "professeur associe" at the

COSPAR. As director of "Fraunhofer-Institut für physikalische Weltraumforschung" (1969–79) he became the father of the two AEROS satellites, launched in 1972 and 1974.[10]

He was actively engaged in the

ionogram reduction and was vice-chairman and chairman of the ionospheric committee 1966–72.[11] He was the father and longtime chairman of the International Reference Ionosphere that since 1999 is International Standard.[citation needed
]

Rawer was

University of Düsseldorf, corresponding member of the International Academy of Astronautics and of "Oesterreichische Akademie der Wissenschaften Wien". He died on 17 April 2018 in March, Breisgau, two days before his 105th birthday.[12]
