ESP32 Satellite Attitude Kit: Quaternion Logging at 200Hz
ESP32 Satellite Attitude Kit: High-Speed Quaternion Logging at 200Hz
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Assemble a laboratory-grade satellite attitude determination unit that fuses accelerometer, gyroscope, and magnetometer data from the ICM-20948 9-axis IMU. The onboard ESP32 runs a Madgwick filter to compute quaternion orientation angles and writes them to SD card at 200 Hz with microsecond-accurate timestamps. This is the exact signal chain used in low-earth-orbit CubeSat ADCS prototypes - now in a tinkerable, benchtop format.
What You'll Build
A self-contained attitude logger that samples raw 9DOF data from the ICM-20948, applies the Madgwick AHRS algorithm in real time, and stores quaternion logs alongside RTC-timestamped entries. The 0.96-inch OLED shows Euler angles instantaneously. Powered by a 3.7V LiPo cell with integrated TP4056 charging, the system runs untethered for hours, letting you simulate spacecraft attitude sensing on a desk or inside a rocket payload bay.
What You'll Learn
- Implement the Madgwick AHRS filter on ESP32 to compute drift-free quaternions
- Fuse 9-axis IMU data from accelerometer, gyroscope, and magnetometer
- Log sensor data to SD card at continuous 200 Hz using SPI and FATFS
- Design a battery-powered embedded system with buck regulated supply
- Interface a real-time clock (DS3231) for microsecond-precision timestamping

Who This Kit Is For
Designed for CubeSat student teams, aerospace engineering undergrads, and researchers performing attitude control experiments. It matches final-year B.Tech projects at IITs, NITs, and VIT, and aligns with ISRO- and Smart India Hackathon-level space technology challenges. If you need a repeatable quaternion data source to validate your flight algorithms on a bench, this kit delivers a fully documented, hackable reference design.
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 talk to the AI companion, or reach out on WhatsApp. We'll walk you through debugging, soldering, and firmware issues step by step.
Can I increase the logging rate beyond 200Hz?
The ICM-20948 magnetometer output caps at 225Hz; with optimized SPI and SD buffer writes, you can approach 250Hz, but we guarantee stable logging at 200Hz.
Does the kit include pre-flashed firmware?
No, we provide complete source code and AI-guided steps to compile and upload via Arduino IDE or PlatformIO, so you understand every layer of the filter.
Can I feed the quaternion data to an external flight computer?
Yes, the serial output streams real-time attitude, and the SD card logs can be ingested directly. The system is designed as a transparent sensor block for larger avionics stacks.
ICM-20948 9DOF IMU + magnetometer implements Madgwick AHRS filter. Quaternion attitude logged to SD at 200Hz.
