Essential Technical Files For Designing And Operating 3U Cubesats: A Comprehensive Guide
3U CubeSat Files and Details A 3U CubeSat is a type of miniaturized satellite composed of three 10×10×10 cm units, forming a structure of 10×10×30 cm. These satellites are commonly used for academic, research, and commercial missions in Low Earth Orbit (LEO). To design, test, and operate a 3U CubeSat, several types of technical files and documents are essential. Below is a summary of the key files involved: 1. Mission and System Requirements Document (MSRD) This document outlines the satellite's mission objectives, performance criteria, and system-level requirements. It defines payload needs, power budgets, orbit specifications, and lifetime expectations. 2. Interface Control Document (ICD) ICDs describe how different subsystems within the CubeSat interface with each other and with ground support systems. It includes mechanical, electrical, and software interfaces. 3. Subsystem Design Documents Each subsystem—such as power (EPS), attitude control (ADCS), communication, command and data handling (C&DH), and payload—requires individual design files. These include block diagrams, schematics, PCB layouts, and simulations. 4. Software Files This includes flight software source code (typically written in C/C++), bootloaders, and ground station scripts. Ground support software, like mission planning tools, is also documented. 5. Bill of Materials (BOM) A detailed list of components used in the CubeSat, including part numbers, specifications, suppliers, and costs. This helps with procurement and assembly. 6. Assembly, Integration, and Test (AIT) Procedures AIT documents guide the physical assembly and integration of the CubeSat. It also includes environmental test procedures such as vibration, thermal vacuum, and EMI/EMC tests. 7. Launch Interface Agreement (LIA)
