Design takeaway

How to apply

When developing new satellite subsystems or attitude control mechanisms, consider using 3D-printed breadboards and custom rigs to quickly assemble and test integrated systems before investing in flight-qualified hardware.

Project actions

01Use CAD software to design your 3D-printed components for precise fits.
02Document the limitations of your test environment thoroughly.

Method & Evidence

AimTo assess the feasibility and performance of a low-cost CubeSat attitude control system (ACS) using COTS components and a 3D-printed testbed.

MethodExperimental validation using a physical prototype and simulated environment.

ProcedureAn ACS was designed and integrated onto a 3D-printed 3U CubeSat breadboard. A custom 3D-printed air-bearing was developed to allow for free movement of the breadboard. The integrated system, including COTS sensors, reaction wheels, and a micro-propulsion system, was tested in a laboratory environment to evaluate open and closed-loop control capabilities and pointing accuracy.

ContextAerospace engineering, CubeSat development, attitude control systems.

Variables

IVType of testbed (e.g., 3D-printed breadboard vs. traditional)

DVPointing accuracy (degrees)

CVCOTS components used, control algorithms, environmental conditions (within lab limitations).

Strengths & Limitations

Strengths

+Demonstrates practical application of 3D printing in aerospace prototyping.
+Successful validation of sub-degree pointing accuracy with low-cost components.

Limitations

The cost and availability of specific COTS components can be a constraint, and the accuracy of 3D printing may limit the precision of some parts.

Reliability & validity

Reliability could be assessed by repeating tests multiple times to check for consistent results. Validity is supported by achieving the target pointing accuracy, but limited by the environmental simulation.

Think critically

To what extent can a ground-based test environment, even with innovative setups like air-bearings, truly replicate the complex dynamics and conditions of space for attitude control system validation?

Design Principles

"Leverage rapid prototyping and COTS components to create functional, low-cost testbeds for validating complex system performance in simulated environments."

This approach significantly lowers the barrier to entry for developing and testing sophisticated aerospace components. By leveraging rapid prototyping and readily available components, design teams can iterate quickly and validate performance in a simulated environment before committing to expensive flight hardware.

What This Means for Your Design

You can build and test a working model of a satellite's pointing system using a 3D printer and off-the-shelf parts, and it can be very accurate, but the test environment isn't exactly like space.
