Orbital and ground control system reliability factors influencing the throughput of the multi-satellite orbital constellation ground control

The paper considers a problem of analyzing the ground control loop throughput for a multi-satellite orbital constellation taking into account the influence of random reliability factors of the orbital and ground systems. It formalizes the throughput analysis problem and proposes its solution as finding the equilibrium condition between the random service requests flow from a spacecraft and a possibility of satisfying them by the ground facilities. The obtained condition makes it possible to assess an increase in the ground loop actual required throughput compared to that expected taking into account reliability factors of the facilities and the need to ensure dynamic operations with a spacecraft as part of the constellation. The paper provides results of the simulation modeling. Quantitative assessment of the actual required throughput were obtained.
