Problems solved by technology

This design has disadvantages such as low system integration, low functional density of the whole star, and inconvenient installation and debugging.
The subsystems of the CubeSat platform are simply connected through stacking and cable connections, without considering the full sharing of resources on the star, resulting in a waste of resources
The existing PC104 and cable connection methods between the sub-systems of the existing CubeSat limit the layout of the satellite to a large extent, and cannot make full use of the entire star space, and the plug-in stand-alone installation will make the system unreliable to a certain extent
During the test process, it needs to go through the steps of stand-alone test - sub-system level test - whole star electrical test, etc. During the test process, the mechanical interface and electrical connector between the boards need to be installed and plugged in multiple times, and the stacked whole star structure is tested The openness of personnel is not enough, which brings a lot of inconvenience to the test

Embodiment Construction

[0032] The present invention firstly complies with the size requirements of the one-unit cube star standard, and integrates the standard one-unit cube star structure. CubeSat integrated electronic system design integrates the advantages of flexible circuit boards and traditional printed circuit boards, integrates the systems on the star into one circuit board, weakens the boundaries of the subsystems on the circuit board, shares the resources on the star, and integrates the electronics of the whole star. Highly integrated, realizing the integrated electronic integration on the star and the cable-free connection between various systems. Using additive manufacturing technology to process complex mechanical structures, no longer sticking to the idea that the existing satellite platform and the payload part are independent in space, centering on the remote sensing camera on board, the entire circuit board is folded around the payload in an orderly manner, The integrated design of ...

Abstract

The invention discloses a cable-free high-density cubesat and an assembly method thereof. The cable-free high-density cubesat comprises a main structural frame 1, a solar cell array 2, an antenna plate 3, an on-satellite integrated electronic system 4, a momentum wheel 5, a gyroscope 6, a magnetorquer 7, a remote sensing camera 8, a battery pack 9, a camera fastening frame 10 and a lead screw 11.The main structural frame 1 includes an upper end cover 101 and a satellite shell 102, and the momentum wheel 5, the gyroscope 6, the magnetorquer 7 and the camera fastening frame 10 are fixed into the satellite shell 102; and the remote sensing camera 8 is fixed into the camera fastening frame 10, the on-satellite integrated electronic system 4 is a multi-layer circuit board formed by folding a whole circuit board, the multi-layer circuit board is placed in the satellite shell 102, and the solar cell array 2 is fixed to the side wall of the main structural frame 1. The cable-free high-densitycubesat realizes the on-satellite integrated electronic integration and the non-cable between systems, realizes the high-density integration of a cubesat, and improves the utilization ratio of the internal space of the cubesat.

Description

technical field [0001] The invention relates to the technical field of satellites, in particular to a cable-free high-density cube star and an assembly method thereof. Background technique [0002] Cube stars began in 1999 as a scientific study by the California Institute of Technology and Stanford University. According to the CubeSat design standard, it is stipulated that a cube with a mass of 1kg and a structural size of 10cm×10cm×10cm is a unit, making CubeSat a general standard for micro-nano satellites. With the development of micro-nano technology, integrated multi-functional structure, additive manufacturing technology, integrated integrated electronic system and other technologies and their application on cube stars, this has brought innovation to the design of cube stars, and the performance of satellites has been further improved. The improvement of the satellite information processing capability has been enhanced, the uplink and downlink bandwidth has been increa...
