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 data. The results suggest that with 7–8 dB margin, services can be provided...

The requirements for data rate and capacity in wireless communication systems have increased dramatically over the last couple of decades, and it is expected that this increase will continue in the years to come. Including higher frequency bands providing additional bandwidth is a key strategy to...

Data from a weather radar located above the polar circle in the North Sea are used to estimate the rain attenuation for a satellite link towards a geostationary satellite operating at Ka-band. Radar reflectivity data are obtained along the slant path from a beacon receiver located close to the radar...

This paper describes the main objectives and early achieved results from the MARENOR project. MARENOR is financed by the Research Council of Norway as well as Norwegian industry partners from oil and gas (EM survey company EMGS), fisheries (shipping company and shrimp trawler Remoy), positioning and...

A critical point in cognitive radio spectrum sensing is the ability to detect presence and absence of primary users as fast as possible at very low SNR. In this paper, sequential power detection by cumulative sum and recursive generalized likelihood ratio test is used to detect free spectral slots...
