P88L Portable GNSS Tracker
The P88L is a compact, Green-Gps compatible GPS tracker designed for personal safety and family tracking. Built for seniors, children and lone workers, it combines multi-technology positioning (GNSS, LBS, optional Wi‑Fi and optional Bluetooth) with a straightforward two-button interface and a dedicated SOS button to deliver reliable real-time tracking and timely alerts through the Green-Gps platform.
Mobile and rugged, the P88L supports 4G LTE Cat 1 with backward compatibility to 3G and 2G and regional variants for broad cellular coverage. With fast magnetic charging, long standby in smart working mode, and offline buffer memory, this device is engineered for continuous monitoring and easy integration with Green-Gps for telemetry, alerts and secure location history.
Key Highlights
- Green-Gps compatible GPS tracker for real-time tracking and alerts via cellular networks.
- Multi-mode positioning: GNSS accuracy (~2.5 m when available), LBS, with optional Wi‑Fi and BLE to improve indoor or dense-area fixes.
- Dedicated SOS button, man‑down alert and anti‑lost Bluetooth support for fast incident response and anti-theft / anti-loss scenarios.
- Long battery life with up to 200 hours standby in smart working mode and fast magnetic charging (1800 mA, ~1.5 hours to full).
- Rugged IP67 design and wide operating range (‑10°C to 65°C), suitable for daily carry and outdoor use.
- 8 MB offline buffer memory and OTA (over‑the‑air) updates for reliable data continuity and remote maintenance.
- Compact form factor and accessories (e.g., AGP101 protective pouch) for discreet, comfortable wear.
How It Works with Green-Gps
Integrated with Green-Gps, the P88L streams location and basic telemetry over cellular networks so caretakers, security teams and families can view live position, receive alerts and review trip history. The device’s multi-technology positioning feeds Green-Gps with GNSS fixes when outdoors and supplemental LBS/Wi‑Fi/BLE data when GNSS is unavailable, improving continuity of tracking. Alerts such as SOS and man‑down are forwarded to Green-Gps in real time so operators can act quickly.
- Real-time location and telemetry updates (GNSS/LBS/Wi‑Fi/BLE as available) to Green-Gps dashboards and APIs.
- SOS and man‑down alert delivery with timestamped location and history playback for incident review.
- Step counting and basic activity telemetry for wellness monitoring and contextual reporting.
- Anti-lost Bluetooth support: BLE beacons and sensors can supplement Green-Gps alerts for nearby device separation.
- Offline buffering (8 MB) stores data during temporary coverage gaps and forwards it to Green-Gps when connectivity resumes; OTA updates enable remote maintenance.

Use Cases
- Personal safety for seniors: fall detection (man‑down), SOS alerts and location sharing to caregivers via Green-Gps.
- Child tracking and family monitoring: geo-fence notifications, anti-lost BLE alerts and real-time position for guardians.
- Lone-worker monitoring: remote supervision of field staff with SOS and location telemetry to Green-Gps for rapid response.
- Event and temporary personnel tracking: compact form and long endurance make it suitable for short-term deployments.
- Asset-personnel pairing: use BLE to link people to small assets or equipment for proximity alerts and anti-theft scenarios.
Why Choose This Tracker with Green-Gps
The P88L delivers a focused, reliable solution for personal tracking that integrates cleanly with Green-Gps for real-time tracking, alerts and history. Its strengths are its multi-mode positioning, long battery life with intelligent smart working mode, rugged IP67 build and simple user interface—making adoption fast and user-friendly for non-technical users. OTA support and offline buffering reduce maintenance overhead and improve data continuity for Green-Gps dashboards and reporting.
Note on scope: the P88L is engineered for people-centric tracking and safety telemetry (step counting, SOS, man‑down, BLE anti-lost). For vehicle-centric needs such as ignition inputs, immobilizer control or fuel monitoring, purpose-built vehicle trackers are typically used; however, the P88L can complement fleet management systems by tracking drivers or passengers and reporting person-level telemetry alongside vehicle GPS trackers within Green-Gps.
