Examples of operational capability of NSAT-1 - phase-B report

NSAT-1 is a Norwegian micro satellite primarily for surveillance of the Norwegian waters. Four scenarios are described and simulated to study the coverage and revisit times for NSAT-1. The results shows that the Norwegian waters is covered nearly two times the required 4 times pr day. About 90 % of the revisit times will be about 1 ½ hour in Dwelling mode, decreasing to about 40 % in Scanning mode. An “out-of-area” scenario shows that the Persian Gulf will be covered at least 2 times pr day. Downlinking these data to a ground station in Tromsø, the delay will be about 10 minutes in ascending orbit and about 1 ½ hour in descending orbit.
