Selection of effectiveness criteria of commercial communication satellites

The cost efficiency calculation models for communication satellites were developed considering two financing schemes: at the cost of own funds, and with the use of bank crediting. The cost efficiency indices: basic costs payback period and profitability index were developed for both schemes. Respective calculation methods for cost efficiency indices were developed for both financing schemes. There was proposed the constraint criterion for the cost efficiency factor existence range: the project profitability shall be no less than bank deposit profitability. Using assessed results there were developed guidelines for the payback period restriction: less than one third of the satellite lifetime.
