NNF webinars fall 2021

12. 07

The NNF is pleased to continue our series of webinars from September 2021.

Thursday September 9th  2021 at 15:00 (Swedish / Norwegian time).

 

“GNSS and Scintillations in the Ionosphere of the Arctic” presented by Sarah Schultz Beeck, Technical University of Denmark.

 

Global Navigation Satellite System (GNSS) signals are affected by the media of the ionosphere when traversing it. This can cause strong phase scintillation in the Arctic region, however, there is no continuous real-time monitoring of the ionosphere above Greenland at the moment. The thesis investigates possibilities for real time monitoring of the ionosphere above Greenland, based on data from geodetic 1 Hz GNSS stations. This, near real-time monitoring of the ionosphere and its scintillation, can be an advantage for GNSS users, and is a step towards improving the safety of navigation in the Arctic. The novelty of the work is the application of the kriging method as basis for rate of total electron content index (ROTI) maps in the Arctic.

November 25 2021, 15:00 (Swedish / Norwegian time)- Radio Frequency Interference in Norway and Europe

 

Radio Frequency Interence (RFI) or Jamming is a threat to all users of satellite navigation equipment. Nicolai Gerrard from the Norwegian Kommunications Authority (NKOM) and Aiden Morrison from SINTEF will present on the past, present and expected future of RFI in Norway and Europe generally. Specific topics will include examples of jamming devices apprehended in Norway, review of motivations for the use of illegal signal jamming, statistics from long term environment monitoring campaigns and how this impacts the general users of GNSS as well as autonomous and safety critical systems.

 

December 2 2021, 15:00 (Swedish / Norwegian time) - Animal Navigation presented by Professor Emily Baird from Stockholm University.
