Researchers will spend the next two years gathering meteorological data from Svalbard in the north to Nittedal in the south. The aim is to find out how much satellite signals are adversely affected by rain, atmospheric pressure and other meteorological conditions.
The data collected will be used to update currently available statistical information, and will be available to everyone. This will be of interest to companies involved in building satellite systems and ground receiving stations.
Large bandwidths – high frequencies
Broadband communication at high latitudes will become more important in the next few years as activity in the shipping and oil industries increases. In this region, satellites often provide the only means of communication because facilities are located outside the coverage of ground-based communications systems.
However, broadband communication requires large bandwidths – which require high frequencies. And signals at high frequencies have proved to be more affected by rain and other meteorological conditions than signals at lower frequencies.
Signals disrupted by the atmosphere
On assignment from ESA, SINTEF ICT is working with Telenor, the Norwegian Defence Research Establishment, the University Graduate Centre and the Norwegian Defence Logistics Organisation to gather meteorological data and find out how much signals are being hampered and how they tend to vary.
