Quality assessment of a satellite communication system using a weather-dependent parametric model

Link budgeting is a crucial part of the satellite communication systems design. The task becomes especially important, when the high-speed transmission is required. In this case, it is necessary to find a compromise between the system technical capabilities and the communication link quality accounting various conditions, including weather. This article proposes a model of a telecommunications system, which calculates the probability of data transmission error based on the results of the data transmission modelling, and allows estimating the final transmission speed. The use of a parametric signal attenuation model makes it possible to perform an assessment for a ground link station at any point on the Earth with various signal attenuation factors occurred probability: cloudiness and precipitation. Simulation results are presented in the form of two-dimensional graphs for the ease of communication system qualitative analysis.
