FIELD: physics.SUBSTANCE: invention relates to the design of artificial satellites, primarily CubeSat picosatellites (10×10×10 cm), which can be used to control the process of separation and the state of space objects. A picosatellite has a cubic housing and is fitted with antennae, solar and storage batteries. Electronic printed-circuit boards are mounted inside the housing. The housing is made of polyetheretherketone with carbon nanotubes (TECAPEEK ELS nano, density 1.44 g/cm). All faces of the housing, including under the solar battery, there are protective plates made of polyimide-based plastic with molybdenum disulphide filler. The plates provide electrical and thermal decoupling (in the temperature range of -270°C to +300°C) of the solar battery and the housing. Said design of the housing gives the housing the required robustness and current-conducting properties (owing to the nanotubes), high radiation protection (without secondary radiation) and other useful properties. Different faces of the housing are fitted with video camera lenses (at least five).EFFECT: longer service life of the picosatellite.2 cl, 8 dwg |
