Frequency Plan Design for Multibeam Satellite Constellations Using Linear Programming

Satellite Routing for mobile users under uncertainty in High Throughput constellations

“…Satellite routing + Frequency assignment with uncertainty: in this experiment, we take the same premises as in the previous experiment, but we combine the proposed Satellite Routing solution with the frequency assignment strategies proposed in [65] and briefly described in Section 5.3 to assess the different tradeoff and performance. In this experiment, the PSO is used to solve routing for the uncertainty formulation and for the deterministic formulation, then the frequency assignment is solved using the proposed approach in [37] together with the use of the different strategies mentioned above. Different combinations of strategies and offline and real time routing are used.…”

“…In [37], Garau et al propose an iterative linear programming method to solve the frequency assignment problem and that allows them to encode different objectives in the objective function, such as maximizing bandwidth, minimizing power consumption, or minimizing the number of active frequency reuses.…”

“…The constellation parameters used for the experiments in this section are described in For all the experiments in this section, the PSO has been used to solve the satellite routing problem, and the approach described in [37] has been used to solve the frequency assignment problem. The different combinations of strategies used in this section are described in Table 5.6, with the values used for their parameters.…”
