Chip satellite based on electrical activity polymer and attitude control method of chip satellite

Abstract

The invention discloses a chip satellite based on an electrical activity polymer and the attitude control method of the chip satellite. According to the chip satellite disclosed by the invention, according to the principle of angular momentum conservation, through deformation of the electrical activity polymer arranged on the periphery of a chip satellite center platform, the mass distribution of a whole system is changed, so that attitude maneuver of the chip satellite is realized. According to the attitude control method of the chip satellite provided by the invention, a conventional chip satellite attitude control method gets away from the dependency of magnetic field and an ionosphere, so that the attitude maneuver of the chip satellite can be realized at any position in space, and the application range of the chip satellite is greatly extended; after the process of the attitude maneuver of the chip satellite is completed, the chip satellite system still keeps the plane condition before the attitude maneuver is performed, so that under the plane condition, an antenna structure formed by electrical activity polymer drivers is under a condition that electrifying is not needed, and the chip star system can maintain the realized attitude maneuver without consuming any energy after the attitude maneuver is performed.

Description

technical field [0001] The invention belongs to the field of aerospace, and in particular relates to a chip satellite based on an electroactive polymer and an attitude control method thereof. Background technique [0002] With the development of micro- and nano-technology, micro-satellites such as nano-satellites and pico-satellites have gradually become an important part of the space system, and have begun to transition from the stage of scientific exploration and technology experimentation to the stage of commercial operation. At the same time, the chip satellite concept proposed by the United States and Europe has attracted wide attention due to its advantages of low cost, rapid development and convenient launch. This chip satellite is realized by integrating units such as micro-electromechanical systems (MEMS), micro-opto-electromechanical systems (MOEMS) and complementary metal-oxide semiconductors (CMOS). Therefore, it is extremely small in size, extremely light in we...

Problems solved by technology

However, the above methods are only applicable to celestial bodies with magnetic fields or ionospheres. For spaces without magnetic fields or ionospheres, chip satellites cannot achieve attitude maneuvering, which greatly limits the application range of chip satellites.
