Star Tracker Attitude Sensor Variant 28 Kit with ESP32 + LED
Star Tracker Attitude Sensor Variant 28 Kit with ESP32 + LED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit enables you to build a genuine star tracker attitude sensor — the same principle used in satellite navigation. By capturing a star field image with the ESP32-CAM and running Python-based pattern recognition, you’ll output a quaternion that defines your spacecraft’s orientation in three-dimensional space. Every component, from the high-precision ICM-20948 IMU to the DS3231 real-time clock, is included to create a self-contained, deployable unit.
What You'll Build
You’ll assemble and calibrate a compact star tracker unit that captures night sky images, identifies known star patterns, and computes an accurate attitude quaternion. The onboard OLED displays real-time orientation data, while a microSD card logs the full sensor stream for post-flight analysis in MATLAB or Python. The system mimics the functionality of a real satellite star tracker, ready for integration into a rocket payload bay or high-altitude balloon experiment.
What You'll Learn
- Star field image acquisition and pre-processing with ESP32-CAM
- Python-based star pattern recognition and quaternion attitude algorithms
- IMU, RTC, and buck converter integration for space-grade timing and motion sensing
- Soldering, PCB prototyping, and power management for deployable electronics

Who This Kit Is For
This kit is designed for B.Tech ECE/EEE final-year projects, research scholars developing small satellite attitude systems, and Smart India Hackathon teams building space tech solutions. It is equally valuable for faculty members at IITs, NITs, VIT, and BITS Pilani running embedded systems or aerospace labs. If you are working on a CubeSat ADCS prototype or a high-altitude balloon star tracker experiment, this kit provides the exact hardware and software foundation you need.
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?
Use the QR code on the box to access the AI companion trained on this kit; it provides step-by-step guidance and troubleshooting. You can also reach us on WhatsApp for personal support.
Do I need a clear night sky to test the star tracker?
Yes, a clear sky with visible stars is required for field calibration, but the kit includes a simulated star field mode on the OLED for indoor testing and code validation.
Can this sensor output be fed into a flight control system?
Absolutely. The quaternion data stream can be transmitted over UART or Wi‑Fi to any compatible flight computer, making it suitable for suborbital rocket or high-altitude balloon attitude experiments.
Is soldering experience needed, and is the soldering iron included?
Yes, you will solder components onto the prototype boards; a basic soldering iron and solder wire are included in the kit.
ESP32-CAM captures star field image. Python star pattern recognition returns spacecraft attitude quaternion.
