10.2 Radio astronomy stations
Certain restrictions on the use of VEGAPULS 69 outside closed vessels result from the radio
license. You can find these restrictions in chapter "
Radio license for Europe
". Some of these restric-
tions have to do radio astronomy stations. The following table states the geographic positions of
radio astronomy stations in Europe:
