Drone GPS Navigator Kit v5
Drone GPS Navigator Kit v5 — ESP32-Based GPS-Disciplined RTC for Sub-Microsecond Drone Navigation
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your drone’s timing accuracy from millisecond drift to sub-microsecond precision. This kit uses the NEO-6M GPS module’s pulse-per-second (PPS) output to discipline a DS3231 real-time clock, while an ESP32 orchestrates the sync logic and drives a bright OLED showing lock status and holdover information. It’s a self-contained precision timing module you can embed directly into any UAV telemetry stack.
What You’ll Build
A compact, soldered module that continuously synchronizes your drone’s onboard clock to GPS satellite time. The OLED displays live PPS integrity, sync lock, and holdover drift in microseconds when satellite signal is lost—giving your flight logs and sensor timestamps laboratory-grade accuracy without the lab equipment.
What You’ll Learn
- Disciplining a DS3231 RTC using a GPS module’s PPS output for sub-microsecond precision
- Parsing NEO-6M UART sentences on ESP32 and extracting time and PPS data
- Driving an I2C OLED to display real-time sync status, holdover countdown, and drift
- Soldering a noise-sensitive mixed-signal PCB with proper decoupling capacitors and resistor networks

Who This Kit Is For
This advanced kit is designed for B.Tech ECE/EEE students developing UAV telemetry and navigation payloads, Smart India Hackathon teams pushing real-time precision boundaries, and researchers at IIT, NIT, VIT, or BITS who need a rugged GPS-disciplined clock reference. If you’ve moved beyond hobby-grade GPS timestamps and need flight log integrity at the microsecond level, this kit delivers.
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 the AI companion that knows this kit’s circuit and firmware in detail. You can also send photos over WhatsApp and our team will help debug.
Does this kit include a drone frame or flight controller?
No, this is a precision timing module you integrate into your existing drone. It supplies a sub-microsecond clock reference; you provide the flight electronics and airframe.
How long does the RTC hold sub-microsecond accuracy after GPS signal is lost?
The DS3231 typically drifts a few microseconds per day. After disciplined lock, holdover drift stays within single-digit microseconds for several hours, and the OLED calculates and displays the estimated error continuously.
Can I use a different GPS module, like a NEO-7M or NEO-8M?
The kit is pre-validated with the included NEO-6M. Other modules with PPS output may work, but you’d need to adjust timing parameters. The AI companion covers only the supplied NEO-6M configuration.
Drone — GPS PPS signal disciplines DS3231 RTC to sub-microsecond accuracy. OLED shows sync status and holdover.
