Abstract—

This paper considers an approach to approximating the sensor data of an autonomous navigation system installed on the Russian segment of the International Space Station (ISS) based on the application of a mathematical model simulating the orbital motion of a spacecraft (SC) in which the midship area is computed with allowance for the aerodynamic drag forces using a geometric model of the outer surface of the station. The approach described in the work is employed to analyze the data of intervals up to ten days of the ISS flight in January and June of 2018. This paper presents the results of mathematical simulation using the described mathematical model and the standard mathematical model by the ballistic coefficient. The proposed mathematical model shows significantly better approximation indices.
