The possibility of data transmission via the channels: MCC Globalstar nanosatellite, nanosatellite Globalstar nanosatellite is shown. The duration of communication sessions via the channel MCC Globalstar nanosatellite and the channel nanosatellite Globalstar nanosatellite is analyzed Potential volumes of data transmitted between two nanosatellites are determined. Stochastic analysis of the possibility of data transmission between two spacecraft is performed and the possibility of data transmission between two spacecraft, depending on the data volume and load level of the Globalstar system is assessed.</p>NanosatelliteLEO satellite communication systemdata transmissionorbital constellationcommunication sessionmission control centerGlobalstardata exchangeНаноспутникнизковысотная система спутниковой связипередача данныхорбитальная группировкасеанс связицентр управления полётомGlobalstarобмен данными[1.
