| description | An optoelectronic telescopic lens-type complex is proposed for the purpose of creating a domestic constellation of Earth remote sensing satellites with the ability of timely obtaining of the imagery on-demand. A thermal control system based on electric heaters was chosen to maintain the optimal thermal conditions of the lens telescope. The calculation of the objectives thermal mode was carried out on the basis of a 3D model taking into account actual operational conditions of the spacecraft in its orbital motion. The dynamics of the transient temperature fields of the objective was calculated using the finite- element method under various operating conditions of the microsatellite: stabilization of the thermal regime, Earth remote sensing, emergency failure of the heaters. It is shown that the thermal control system maintains a predetermined temperature range of the optical elements under nominal operating conditions with moderate energy consumption. |
