Scientific objectives
To monitor the auroral activity over Svalbard, in particular in connection with measurements of Global Navigation Satellite System signal scintillations. In particular, to study the connection between auroral precipitation and the degradation of GNSS signals as a results of small-scale ionospheric plasma density structuring, also in relation to in-situ plasma measurements from satellites like Swarm and NorSat-1. Provide scientific context (activity level, boundary locations) in support of rocket campaigns. Improve our understanding of the relationship between optical and plasma velocity transients. Experimentally define two-dimentional plasma flow patterns (EISCAT/ESR/CUTLASS) around frequently observed cusp/cleft auroral transients.
