Cold Gas Thruster Attitude Controller Variant 21 Kit with Arduino Mega
Build a Satellite Cold Gas Thruster Attitude Controller with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Simulate the complete orientation control system of a satellite using cold gas thrusters — without a vacuum chamber or real propellants. The MPU6050 IMU senses pitch, yaw, and roll deviations, while six relays trigger in pairs just like solenoid valves would on a real spacecraft. Build this advanced rocketry simulator and watch the 0.96in OLED display live orientation angles alongside thruster firing indicators.
What You'll Build
A self-contained prototype that actively responds to tilt in all three axes. When you manually disturb the sensor, the controller computes error angles and fires the appropriate pair of thrusters to counteract rotation. LEDs light up in real time to show which "thrusters" (relay-solenoid combos) are active, and the OLED screen confirms the system’s correction effort. It’s a fully functional closed-loop attitude controller — the same logic that flies on CubeSats.
What You'll Learn
- Write Arduino Mega firmware that reads MPU6050 raw data and converts it to Euler angles using sensor fusion
- Program a PID control loop to compute required thruster on-times for pitch, roll, and yaw correction
- Interface 5V relay modules to simulate solenoid valve firing, with safe flyback diode protection
- Integrate an I²C OLED display to visualize live orientation data and thruster states

Who This Kit Is For
B.Tech ECE, EEE, and Aerospace engineering undergraduates working on student satellite orientation control subsystems will find this kit directly applicable. It’s a proven project for Smart India Hackathon teams prototyping space technology, as well as for advanced tinkerers at IIT, NIT, VIT, or BITS rocketry clubs. If you need a hardware-in-the-loop demo of attitude control logic, every component here matches what you’d use in a scaled engineering mockup.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to open your AI companion, which guides you through wiring, calibration, and code logic specific to this thruster controller. WhatsApp support is available if you need human assistance.
Can I replace the relay modules with real solenoid valves?
Yes, the relay outputs and diode protection are identical to what you’d use with 12V solenoid valves. Just ensure the total current draw stays within the adapter rating, and the AI companion will help you verify the connections.
Does this kit include pre-written Arduino code?
No — developing the control algorithm yourself is the key learning outcome. The AI companion explains the PID structure, sensor reading steps, and relay mapping so you can write and understand every line.
Is the MPU6050 pre-calibrated?
The sensor arrives uncalibrated. Calibration is part of the build process: you’ll learn to zero out offsets using simple routines, and the AI module provides sample calibration sketches tailored to this kit.
Solenoid valves simulate cold gas thrusters firing in pairs for pitch, yaw and roll control from MPU6050.
