In recent years, the space industry has seen a significant shift towards the development and deployment of smaller and more affordable satellites, known as CubeSats. These miniaturized spacecrafts have revolutionized the way space missions are planned, executed, and operated. They have opened up new opportunities for academic, research, and commercial organizations to participate in space exploration, bringing space closer to the masses.
A CubeSat is a type of nanosatellite, typically measuring 10 cm x 10 cm x 10 cm (1U) and weighing less than 1.33 kg. CubeSats can be combined to form larger spacecraft, with 2U, 3U, and 6U being the most common configurations. Their compact size and low cost make CubeSats ideal for a wide range of applications, including earth observation, scientific research, technology demonstrations, and educational missions.
One of the key advantages of CubeSats is their ability to ride along as secondary payloads on larger launches, reducing the cost and complexity of deployment. This has enabled organizations with limited resources to have access to space and conduct their missions. In addition, CubeSats have a short development cycle, allowing organizations to quickly adapt to changing requirements and take advantage of new technologies.
Making a CubeSat involves several key steps, including mission definition, system design, payload development, and launch preparation. In this article, we will explore the best tools available for each of these steps, to help you build a successful CubeSat mission.
Mission Definition
The first step in CubeSat development is to define the mission objectives, which will dictate the spacecraft's design and determine the necessary payloads. Some questions to consider when defining your mission include:
- What do you want to achieve with your CubeSat?
- What scientific or technological experiments do you want to conduct?
- What kind of data do you want to collect?
- What is the target orbit and altitude for your CubeSat?
- What are the power, communication, and environmental requirements for your CubeSat?
To help answer these questions, you can use online tools such as the CubeSat Design Specification (CDS), which provides a comprehensive guide to CubeSat design, development, and operations. The CDS is updated regularly to reflect the latest industry standards and best practices, and is a valuable resource for CubeSat makers of all levels.
System Design
Once you have defined your mission, the next step is to design the CubeSat system, which includes the spacecraft bus and the payloads. The spacecraft bus provides the structural, thermal, power, communication, and attitude control systems for the CubeSat, while the payloads are the scientific or technological instruments that perform the mission-specific tasks.
To design your CubeSat system, you will need to use CAD (Computer-Aided Design) tools such as AutoCAD, SolidWorks, or Fusion 360. These tools allow you to create 3D models of your CubeSat, including the internal components and external features such as solar panels, antennas, and deployable structures. They also allow you to simulate the CubeSat's performance in orbit, helping you identify and address any potential issues before launch.
Payload Development
The payload is the heart of your CubeSat mission, and it's crucial to select the right tools and technologies to meet your mission requirements. Some popular payloads for CubeSats include cameras, spectrometers, magnetometers, and particle detectors.
For payload development, you will need to use electronics design tools such as Altium Designer, Eagle PCB, or KiCAD. These tools allow you to design and test the electronic circuits for your payload, including the power
