A DIY open-source antenna tracker system for drones with 360° continuous rotation and multi-protocol telemetry support.
u360gts is an open‑source antenna tracker system for drones that uses telemetry data to automatically rotate a ground antenna and follow the aircraft's position. It supports 360° continuous rotation and multiple telemetry protocols, making it compatible with a wide range of flight controllers and radio systems. The project provides both firmware for STM32‑based boards and hardware designs for a complete DIY tracking solution.
FPV hobbyists, drone enthusiasts, UAV professionals, and DIY electronics builders who need a flexible, universal antenna tracker for improving video/control link reliability.
Developers choose u360gts because it is a free, community‑developed alternative to commercial trackers, with broad hardware compatibility, automatic protocol detection, and features like OLED status display and PID control for accurate tracking.
The Universal 360º Continous Rotation Tracker System for Drones (UAVs, RPAs and FPV).
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports multiple telemetry protocols with automatic detection, making it adaptable to various drones and flight controllers like Betaflight or ArduPilot, as highlighted in the features list.
Open-source under GPLv3 and developed by the FPV community, ensuring free access, peer support, and continuous improvements through forums and groups.
Includes 360° continuous rotation, OLED display for real-time status, PID control for accuracy, and sound alarms, enhancing tracking performance and usability.
Configurable via cross-platform GUI tool (u360gts-configurator) and serial CLI, offering multiple ways to set up and tune the system for different needs.
Firmware is designed only for STM32 F1/F3 boards like NAZE32, restricting compatibility with newer or alternative microcontrollers, which may limit future upgrades.
Requires hardware assembly, firmware flashing, and configuration via CLI/GUI, which can be challenging for users without electronics or programming experience.
Help is primarily through Facebook groups and forums, lacking formal documentation or professional support channels, which may delay issue resolution.
