“…The resulting heat flux was set to 1460 W/m 2 . The initial temperature of the satellite was set to be 40 о С, as the averaged measured value, obtained from telemetry [4]. The analysis was carried out for the following starting conditions:  inclination of the satellite's orbit is 90 о ;  initial temperature for all structural elements is 40 о С;  satellite stays in the "Overheat" mode for 24 hours;  the heat flux during "Overheat" mode is constant;  the satellite is made from composite aluminum panels, covered with photo elements made of GaAs.…”

Abstract. The purpose of this study is to perform an analysis of the process of experimental testing of the thermal control system of the "AIST" small satellite, using the computer simulation of the satellite's flight in the "TERM" software package. Based on the telemetry data, obtained by the Samara University satellite ground control center, actualized parameters of the ground testing process were proposed. The ground testing parameters were verified by calculation of the satellite's panels temperatures using the "ANSYS Thermal" software system both for the initial conditions obtained from the ground testing documentation and the ones that were proposed after the analysis of the thermal flow on the satellite.

The article examines the issues of determining the light-and-shadow situation and its impact on providing energy balance on the orbits of two small satellites of the AIST series. Ensuring energy balance in the operation of mission equipment becomes particularly relevant in the case of power limitations caused by both the degradation of spacecraft systems and the factors of outer space. The main purpose of the article is to solve the problem of increasing the efficiency of the power supply system of AIST-series small satellites operating under resource constraints. Firstly, modeling of the lighting situation on the orbits of small satellites was carried out. Secondly, the telemetric information of AIST small satellites for the whole period of operation was examined. In addition, the influence of the light-and-shadow conditions on the parameters of the power system of a small satellite was analyzed. As a result, an algorithm for estimating the energy balance, taking into account the influence of the light-and-shadow situation was proposed. Using the proposed algorithm made it possible to take into account the influence of seasonal variations in the light-and-shadow environment on the possibility of ensuring energy balance in the operation of mission equipment
