Indoor Drone Tracking ±2cm Precision | Marvelmind
What This Video Covers
This 16-second video demonstrates Marvelmind's indoor positioning system tracking a quadcopter with ±2cm accuracy in a 10×5 meter room. A lightweight 25g mobile beacon mounted on the drone reports its position at up to 16Hz, with stationary beacons placed on walls providing reference points. The system delivers real-time location data accessible via USB modem, UART, SPI, or I2C interfaces—perfect for autonomous indoor drone applications and warehouse automation.
Key Takeaways
- Achieves ±2cm positioning accuracy for autonomous drones in GPS-denied indoor environments
- Lightweight 25g mobile beacon minimizes payload impact on small aerial platforms
- Updates position at up to 16Hz for responsive flight control and real-time navigation feedback
- Multiple interface options (USB, UART, SPI, I2C) simplify integration with existing flight controllers
- Ultrasonic RTLS technology works reliably through walls and requires no external infrastructure
- Suitable for autonomous robots, warehouse automation, and precision indoor applications beyond drones

FAQ
Detailed Overview
This compelling demonstration showcases Marvelmind's ultrasonic indoor positioning technology achieving centimeter-level accuracy for autonomous drone flight. The copter carries a 25-gram mobile beacon that continuously transmits its position to stationary beacons installed on the room's walls, enabling real-time tracking with ±2cm precision and update rates up to 16Hz. Unlike GPS-dependent systems, this RTLS solution works reliably indoors where satellite signals cannot penetrate. The location data streams from the mobile beacon or PC-connected USB modem, offering multiple integration paths via UART, SPI, or I2C protocols. This makes Marvelmind's system ideal for autonomous indoor robots, warehouse automation, forklift tracking, and drone navigation applications requiring submeter precision. The lightweight beacon design minimizes payload impact on small aerial platforms, enabling extended flight times while maintaining accurate position feedback for autonomous path planning and obstacle avoidance algorithms.
