| Abstract |
The dynamics of the deployed orbital tether system consisting of three nanosatellites is analyzed. In the first stage, the satellite, consisting of three sections (nanosatellites) is separated from the base spacecraft, and performs free movement in orbit with some residual angular velocity. In the second stage, two nanosatellites separate from the central satellite in opposite directions, and a tether system is formed that moves near the vertical. Quite simple control programs that are implemented without feedback are offered. The influence of perturbations in the separation of nanosatellites on the formation of the system and on the movement of nanosatellites around their centers of mass is estimated. Two mathematical models are used to analyze the dynamics of the system: one model is constructed by the Lagrange method and considers satellites as material points; the other model is recorded in a fixed geocentric coordinate system and allows us to estimate the influence of perturbations on the
angular motion of nanosatellites. |
