Summary: | This paper describes experiments and results obtained from propagation measurements with the Orbital Test Satellite (OTS) at the Arctic islands of Spitzbergen (78 N). The elevation angle of the satellite was 3.2 deg and the frequency 11.8 GHz. The experiments carried out included measurements of atmospheric scintillations, cross-polarisation discrimination and space diversity improvements. The measurements showed that the distributions of the received satellite beacon amplitude can be approximated by Rice-distributions. Large diversity gain was obtained by using horizontal spacing of 1 km. A wideband (TV) transmission experiment was also performed with good result.
