The GPT18 is a compact wearable GPS tracker watch designed for reliable personal monitoring — ideal for children, seniors, and lone individuals. Green-Gps compatible out of the box, the GPT18 delivers real-time tracking with GPS/Wi‑Fi/LBS positioning, two‑way voice calling, and a one‑touch SOS emergency alarm, so caregivers and monitoring teams can stay connected and respond quickly. Its intelligent working mode balances location accuracy with battery life, and remote configuration via server, app, or SMS makes deployment and management straightforward within the Green-Gps platform.
Durable and easy to use, the GPT18 combines practical safety features (geo‑fence alerts, low‑battery notice, speed alarm, pedometer step counting) with an IP65 water‑resistant enclosure and an OLED display for simple on‑device interaction. As a Green-Gps compatible GPS tracker, it extends Green-Gps’s telemetry and alerting capabilities to personal safety use cases while fitting into broader device portfolios that support fleet management, anti‑theft and other telemetry scenarios across the Green-Gps ecosystem.
Key Highlights
- Green-Gps compatible wearable GPS tracker providing accurate real-time tracking for personal safety and monitoring.
- Multi-modal positioning: GPS + Wi‑Fi + LBS with AGPS assistance for faster fixes and improved coverage.
- One‑touch SOS alarm and two‑way phone call capability to ensure rapid emergency communication.
- Intelligent working mode that optimizes the balance between location accuracy and battery life for longer deployments.
- Geo‑fence, speed alarm and low‑battery alerts enable proactive notifications through Green-Gps’s platform.
- Pedometer and activity telemetry for basic movement and step counting — useful for caregiver monitoring and light fitness tracking.

How It Works with Green-Gps
When integrated with Green-Gps, the GPT18 streams location and event data to the Green-Gps cloud so operators and caregivers receive timely, actionable information. Green-Gps uses that telemetry to display device position on maps, trigger alerts, and generate reports. Remote configuration feeds allow administrators to tune reporting intervals, geofence boundaries, and alert thresholds without physically accessing the watch.
- Real-time location and telemetry updates via GPS/Wi‑Fi/LBS — visible in Green-Gps dashboards and on-demand mobile views.
- SOS emergency alerts transmitted instantly to Green-Gps with location and call‑backend support for immediate response.
- Two‑way voice call support (GSM) for direct communication between the wearer and caregivers or monitoring centers.
- Geo‑fence alerts and speed alarms forwarded to Green-Gps for automated notifications and escalation workflows.
- Low‑battery and device status telemetry delivered to Green-Gps so you can orchestrate replacements or charging schedules remotely.
- Pedometer and movement data available as basic activity telemetry through Green-Gps for health and wellbeing monitoring.

Why Choose This Tracker with Green-Gps
The GPT18 brings reliable personal tracking to the Green-Gps ecosystem with a productized mix of safety, connectivity, and manageability. Its multi‑mode positioning and AGPS assistance deliver fast fixes and dependable location accuracy, while two‑way calling and SOS support critical voice and emergency workflows. Remote configuration via server/app/SMS reduces maintenance overhead, and the intelligent power mode extends field runtime so devices remain online when you need them most.
While GPT18 is optimized for children and elderly care, choosing a Green-Gps compatible GPS tracker means you gain a unified platform for telemetry and alerts. Green-Gps supports a broad range of devices and features — from personal trackers like the GPT18 to fleet management, anti‑theft, telemetry dashboards, and integrations with fuel monitoring or ignition/immobilizer systems for other compatible units. That flexibility lets organizations scale monitoring and safety workflows without retooling their backend or retraining staff.
