Problems solved by technology

However, this method will significantly affect the light and small characteristics of the satellite on the circuit board, and previous dynamic studies have shown that even a three-dimensional magnetic torque device cannot completely control the satellite attitude in the space environment, because no matter what magnetic moment the satellite produces, it will Under the environment of the earth's magnetic field, the magnetic torquer can only produce the control torque perpendicular to the direction of the earth's magnetic field

Abstract

The embodiment of the invention provides a foldable circuit board satellite. The foldable circuit board satellite comprises at least two non-bendable sub-circuit boards, at least one bendable connecting piece and a driving mechanism, wherein the connecting pieces are connected between the adjacent sub-circuit boards, the included angles between the adjacent sub-circuit boards can be changed by bending the connecting pieces, and the driving mechanisms are connected with the adjacent sub-circuit boards respectively and used for controlling the included angles between the adjacent sub-circuit boards. Therefore, the attitude control capability of the circuit board satellite is improved.

Description

technical field [0001] The invention relates to the field of satellites, in particular to a foldable circuit board satellite. Background technique [0002] Satellite-on-printed circuitboard (PCB Sat) refers to a type of spacecraft that is based on a printed circuit board and is equipped with various semiconductor chip products to achieve simple measurement and communication functions. Since the entire satellite is integrated on a circuit board, the circuit board satellite is lighter than the CubeSat. A simple circuit board satellite has an area of ​​about 100cm2 and a mass of about 100g. At the same time, since the electronic components used on the circuit board basically come from mature commercial shelf products, the manufacturing cost of the circuit board satellite is low and suitable for mass production. The cost of a relatively simple circuit board satellite is only one thousand yuan. [0003] The base of the existing circuit board satellite is a whole circuit board, a...
