Long-Term Measurements of Tropospheric Scintillation at Very Low Elevation Angles - Initial Analysis
Rytír, Martin (2022-05-11)Four years of scintillation measurements at very low elevation angles at Kjeller, Norway are analyzed and compared with the ITU-R model. One year is at Ka band with an elevation angle of 3°, and three years are of simultaneous ... -
Results of a Ka Band Campaign for the Characterisation of Propagation Conditions for SatCom Systems at High Latitudes
Tjelta, Terje; Rytír, Martin; Bråten, Lars Erling; Grotthing, Per Arne; Cheffena, Michael; Håkegård, Jan Erik (2017)Satellite services in the High North are utilized extensively for both communication purposes and for earth and climate observations. This paper presents results of two year measurements at 20 GHz and co-sited meteorological ... -
Three-Site Diversity at Ka-Band Satellite Links in Norway: Gain, Fade Duration and the Impact of Switching Schemes
Rytír, Martin; Cheffena, Michael; Grotthing, Per Arne; Bråten, Lars Erling; Tjelta, Terje (2017)Analysis of two years of measurements from a three-site satellite beacon diversity experiment in Norway is presented. The operating frequency was 19.68 GHz, elevation angles were between 21.7° and 22°, and site separations ... -
Variability of Gaseous Attenuation at Very Low Elevation Angle Slant Paths; Measurements and Modelling
Alsaker, Erik Wangen; Rytír, Martin (2020-07-08)Gaseous attenuation variability for a 3.2° elevation angle satellite link operating at 20 GHz in the Norwegian Arctic is analyzed and compared with different models. At a very low elevation link like this one, gaseous ...
