Overview
This project involves setting up and calibrating a Pozyx UWB positioning system to enable precise indoor localization for autonomous drones and robots.
Problem Statement
GPS signals are unavailable or unreliable indoors and in many maritime environments. UWB technology provides centimeter-level accuracy for positioning in these GPS-denied scenarios.
Challenges & Solutions
| Challenge | Solution | Outcome |
|---|---|---|
| Anchor Placement Optimization | Geometric analysis and iterative testing | Optimal coverage with 4 anchors |
| Pixhawk Integration | Custom MAVLink position messages | Successfully integrated with flight controller |
Progress
✓ Anchor hardware setup
✓ Tag configuration
✓ Position calculation
✓ Pixhawk integration
✓ Indoor positioning validation
