Abstract
This paper describes the main concept and development of a standard platform architecture of 3U Cube Satellite, whose design and performance were implemented and verified through the development of KAUSAT-5 3U CubeSat. The 3U standard platform is built in 1.5U size and developed as a modular concept to add and expand payloads and attitude control actuators to meet the user’s needs. In the case of the electrical power system, the solar panel, the battery, and the deployment mechanism are designed to be configured by the user. Mechanical system design maximizes the electrical capability to accommodate various payloads and to integrate and miniaturize EEE (Electrical, Electronic, and Electromechanical) parts and subsystem functions/performance into limited-size PCBs. The performance of KAUSAT-5 adopting standard platform was verified by mounting the VSCMG (Variable Speed Control Moment Gyro), which is one payload for technical demonstration, at the bottom of the platform and the infrared (IR) camera, which is the other payload for science mission, on the top. The 3U CubeSat equipped with the electronic optical camera is under development implementing the standard platform to reduce development cost and schedule by minimizing additional verification.
Highlights
The interest in micro/nanosatellites and CubeSat has increased, as the time passes by, with the development of miniaturized and lightweight electronic components and manufacturing technologies in the 2000s
In the early stage of CubeSat development, only simple functions were implemented, but in recent years, it has been used for the purpose of prior research or technical verification of core technologies necessary for developing medium and large satellites [1]
The existing 3U CubeSat and state-of-the-art technology were investigated, and the specification of 3U CubeSat platform was selected for design
Summary
The interest in micro/nanosatellites and CubeSat has increased, as the time passes by, with the development of miniaturized and lightweight electronic components and manufacturing technologies in the 2000s. In the early stage of CubeSat development, only simple functions were implemented, but in recent years, it has been used for the purpose of prior research or technical verification of core technologies necessary for developing medium and large satellites [1]. These CubeSats are being developed in various configuration and sizes, among which 3U CubeSats are the most widely developed. Due to the high application of the 3U CubeSat, many CubeSat start-up companies such as Pumpkin, Nano Avionics, and Clyde Space or universities are developing and commercializing 3U CubeSat platform and subsystem modules.
