Out-of-the-box compatibility with MoveLink protocol 1.9/2.0 and remote parameter configuration via platform, mobile app or SMS ensure fast integration into Green-Gps-powered fleet management and security workflows.

Key Highlights

• Green-Gps compatible: integrates using MoveLink protocol 1.9/2.0 for seamless telemetry and real-time tracking on the Green-Gps platform.
• Dual positioning: GPS with LBS fallback and AGPS for improved fix times and reliable location reporting in mixed coverage areas.
• Discrete, lightweight design: measures 85.8 × 30.6 × 10.8 mm and weighs 33 g for easy, concealed vehicle installation.
• Anti-theft features: ACC detection and optional relay for remote engine cut-off provide practical immobilizer capability when required.
• Comprehensive safety alarms: crash/fall detection, vibration and overspeed alerts for theft response and driver safety monitoring.
• Remote management: set parameters and trigger actions via platform, mobile app or SMS for flexible operations management.
• Power resilience: 70 mAh backup battery with power-off and low-battery alerts to maintain reporting and improve recovery chances after tampering.

How It Works with Green-Gps

When integrated with Green-Gps, the TK121 provides continuous location and event data that feed Green-Gps’s real-time tracking and reporting tools. The device transmits GNSS fixes, cell-based location fallback and status telematics using MoveLink protocol, enabling Green-Gps to display live position, trigger alarms, and run automated workflows.

• Real-time location and telemetry updates — GPS/LBS positions and AGPS-assisted fixes for timely tracking.
• Ignition and engine status — ACC detection reports vehicle ignition state to Green-Gps for route and idle analytics.
• Alarm events — crash/fall, vibration and overspeed alerts are forwarded to Green-Gps to trigger notifications and incident workflows.
• Remote immobilizer support — optional relay for remote engine cut-off can be controlled through Green-Gps when configured.
• Remote parameter setting — change device configuration from the Green-Gps platform, mobile app or via SMS for fast updates in the field.

Technical Overview

Use Cases

• Fleet management — continuous real-time tracking, ignition state and safety alerts for small-vehicle fleets and delivery services.
• Anti-theft and recovery — discreet installation with power-off alerts and an optional relay for remote engine cut-off helps secure high-risk vehicles.
• Driver safety monitoring — crash/fall, vibration and overspeed alarms enable rapid incident response and driver behavior analysis.
• Geofencing and location-based workflows — trigger alerts or automated actions when vehicles enter or exit predefined zones managed through Green-Gps.
• Portable asset protection — low weight and compact size make TK121 suitable for concealed tracking of equipment and trailers where discreet monitoring is required.

Why Choose This Tracker with Green-Gps

The TK121 pairs a compact, low-profile hardware design with proven integration via MoveLink, making it a practical choice for organizations deploying Green-Gps-compatible GPS tracker solutions. Its balance of real-time tracking, ignition detection and configurable safety alarms gives fleet managers dependable telemetry for operational decisions, while the optional relay provides a straightforward anti-theft immobilizer option when tighter control is needed.

By consolidating TK121 data into Green-Gps, fleets gain centralized visibility for routing, incident response and analytics. Green-Gps’s platform can combine TK121 location and event feeds with additional telemetry — such as fuel monitoring or external Bluetooth sensors provided by integrations — to build a complete picture of vehicle status and performance without assuming those interfaces are built into the tracker itself.

Choose the TK121 for a discreet, Green-Gps compatible GPS tracker that supports real-time tracking, telemetry reporting and practical anti-theft measures while providing flexible remote management for fast deployments and scalable fleet operations.
