Radiowave Propagation at Ka-band (20/30 GHz) for Satellite Communication in High-Latitude Regions
Rytír, Martin (Master thesis, 2009)Atmospheric impairments are a major obstacle in satellite communications at Ka-band in high latitude regions. This report gives a short summary of the existing models that can be used to model the impairments. Further a ... -
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 (Chapter, 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 (Journal article; Peer reviewed, 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 ...
