Ulbotech T361 OBD-II GPS Tracker
The Ulbotech T361 is a Green-Gps compatible GPS tracker engineered for fast, reliable plug-and-play deployment via a vehicle’s OBD-II port. Designed for fleet management, security and driver behavior monitoring, the T361 exposes engine data, CAN/J1939 diagnostics and real-time telemetry so you can add vehicle-level insight to your Green-Gps platform quickly and without wiring changes.
Compact and robust, the T361 combines a quad-band GSM/GPRS modem with a u-blox 6M GNSS module, an internal immobilizer (engine cut output), and a 3-axis accelerometer to support real-time tracking, anti-theft functions and detailed driving-event analysis. Its integration with Green-Gps enables configurable alerts, reports and remote firmware updates for scalable vehicle and fleet telematics.
Key Highlights
- Plug-and-play OBD-II installation for fast deployment across fleets and rental vehicles.
- Quad-band GSM/GPRS connectivity (850/900/1800/1900 MHz) for wide network compatibility and real-time tracking.
- High-sensitivity positioning with u-blox 6M GNSS and A-GPS for quick TTFF and autonomous position accuracy under 3 m.
- Direct access to engine data and diagnostics (OBD protocols plus SAE J1939 CANBUS) to deliver rich telemetry and ECU-sourced events.
- Built-in immobilizer/engine cut digital output for anti-theft and remote immobilization workflows.
- On-device accelerometer for driver behavior detection (harsh braking, rapid acceleration, harsh cornering) and collision/motion alerts.
- Remote firmware updates (FOTA) and auto APN/time zone detection to simplify large-scale rollouts and maintenance.
How It Works with Green-Gps
When paired with Green-Gps, the T361 delivers continuous location and vehicle telemetry into your platform so you can run real-time tracking, event-driven alerts and scheduled reports. Green-Gps ingests the device’s OBD and sensor streams, normalizes diagnostic PIDs and combines them with GPS fixes to enable fleet management, safety monitoring and anti-theft response.
- Real-time location and telemetry updates sent over GPRS for live tracking dashboards and history playback.
- Vehicle diagnostic data (OBD-II PIDs and SAE J1939) available to Green-Gps for engine status, fault codes and telemetry-driven rules.
- Ignition status and a single digital output for remote engine cut/immobilizer control to support anti-theft workflows.
- Configurable alerts in Green-Gps for geo-fence crossings, unplug/disconnect events, low battery and driver behavior events (rapid acceleration, harsh braking, high RPM, long idling).
- Remote firmware updates (FOTA) via GPRS from an FTP server for centralized device management through Green-Gps’s provisioning tools.
- Engine/ECU data exposed by the T361 can be used by Green-Gps to enable fuel monitoring and consumption analysis where the vehicle ECU provides the necessary PIDs.

Why Choose This Tracker with Green-Gps
The Ulbotech T361 combines the simplicity of OBD-II plug-and-play installation with the telemetry depth fleets and service providers need. As a Green-Gps compatible GPS tracker, it delivers ECU-level data, reliable real-time location and built-in immobilizer control so you can deploy anti-theft, fleet management and insurance telematics solutions without complex installs. Remote FOTA, auto APN/time zone setup and on-device memory reduce maintenance overhead and downtime, while the u-blox GNSS and GSM/GPRS radio ensure consistent connectivity and accurate tracking. If your deployment requires compact OBD-II hardware that feeds rich telemetry into Green-Gps for alerts, reports and remote management, the T361 is a practical, proven option.
Set Up T361
Use with a tracker
-
Set the Operator APN
