Abstract :
At first the heuristic algorithm for optimal sizing of N satellite capacity types (on LES side of link) is compared with algorithm based on exact approach. In all numerical test-examples for mobile network with predicted traffic demands the best possible result is achieved. After that the heuristic is tested through the same test-examples as before, but using various limitations for capacity state values. Only if we apply adequate heuristic approach we can ensure both, significant improvement of QoS (Quality of Service) for capacity availability and minimal capacity expansion cost. It means that our heuristic approach can be successfully applied to short-term or medium-term satellite network planning with finite number of discrete time periods.
