Xexun - U01

The U01 UWB High-Precision Positioning Watch is a professional-grade positioning tag in a wristwatch form factor designed for enterprise and institutional deployments. Green-Gps compatible by design, the U01 delivers centimeter-level indoor positioning when used with UWB anchors and a positioning engine, while streaming vital telemetry — heart rate, blood pressure, SpO2, and activity — to a central management system for real-time tracking and safety monitoring.

Built for personnel tracking, attendance, safety and asset management, the U01 combines rugged, IP68-rated protection with low-power hardware and magnetic charging. Its configurable broadcast interval, SOS button, vibration alerts and OTA firmware upgrades make it an effective Green-Gps compatible endpoint for sites that need precise location, physiological monitoring and robust event reporting in controlled environments such as factories, hospitals and schools.

Key Highlights

• Green-Gps compatible UWB wristwatch delivering up to 10 cm positioning accuracy when used with UWB anchors and a positioning server.
• Real-time telemetry: continuous heart rate, blood pressure and SpO2 monitoring combined with motion/activity and sleep sensing.
• Enterprise-ready durability: IP68-rated enclosure, operating range −30°C to +60°C, and environmental-grade materials.
• Practical safety features: SOS emergency alarm via long touch-button press, vibration notifications and low-battery alarms below 20%.
• Low-power design with a 200 mAh battery, up to 14 days standby and ~2 hours fast charging via magnetic port.
• Optional NFC and a built-in RFID module enabling bidirectional terminal/system messaging and anchor interactions.
• Easy lifecycle management with remote OTA firmware upgrades and configurable UWB broadcast intervals (default 1 s).

How It Works with Green-Gps

The U01 is intended to operate as part of a UWB positioning system integrated into Green-Gps. In a typical deployment, UWB anchors receive U01 broadcasts and send range or time-difference measurements to a positioning engine. Green-Gps ingests that positional data plus the U01’s telemetry to provide real-time tracking, historical trajectories, geofencing, alerts and reporting.

• Real-time location and telemetry updates: Green-Gps receives high-precision coordinates (up to 10 cm) and physiological data for live dashboards and maps.
• SOS and event alerts: the touch-button SOS triggers immediate notifications and integrates with Green-Gps alarm workflows.
• Vital signs and activity telemetry: heart rate, blood pressure, SpO2, motion and sleep metrics upload to Green-Gps for health and safety monitoring.
• Device state and battery: low-battery alarms and vibration notification events sent to Green-Gps for maintenance and response planning.
• RFID/NFC messaging: bidirectional terminal/system communication enables secure ID workflows and proximity events inside Green-Gps.

Technical Overview

Use Cases

• Personnel tracking and attendance in factories, hospitals, schools and prisons — accurate indoor positioning for compliance and timeliness.
• Safety monitoring and emergency response — SOS alarms, physiological telemetry and location enable fast incident handling.
• Patrol and access control — RFID/NFC messaging and geofencing provide audit trails and proximity-based workflows.
• Asset and workflow optimization — historical trajectories and activity data help optimize routes, reduce dwell times and improve operational efficiency.

Why Choose This Tracker with Green-Gps

The U01 delivers a focused solution for organizations that need precise indoor positioning and human telemetry rather than a traditional GPS tracker. As a Green-Gps compatible device, it complements GPS-based devices used in fleet management by filling indoor coverage gaps where GNSS cannot deliver reliable results. Its UWB positioning, combined with vital-sign sensors and bidirectional RFID communication, provides a single endpoint for safety, attendance and asset workflows.

Choose the U01 with Green-Gps when you require dependable real-time tracking, high-precision location data and integrated physiological telemetry in an easy-to-manage package. While features common to vehicle GPS trackers — like ignition monitoring, immobilizer control or fuel monitoring — are not part of the U01’s design, the watch integrates cleanly into Green-Gps deployments alongside vehicle telematics to provide a complete operational picture. With IP68 protection, long standby, OTA updates and configurable broadcast intervals, the U01 is a practical, reliable building block for modern indoor positioning and staff-safety systems.
