The T373A is a plug-and-play OBD-II GPS tracker designed for vehicle tracking and fleet management and is fully Green-Gps compatible. Installed in seconds on any standard OBD-II port, the T373A brings real-time tracking, in-vehicle telemetry and driver behavior reporting to fleets, rental operators, insurers and roadside assistance providers without complex wiring or installation. Its support for multi-band GSM/WCDMA networks, combined with a u‑blox GNSS receiver and rich OBD-II data, makes the T373A a practical choice for scalable, data-driven fleet operations.
Built for reliable anti-theft and operational visibility, the T373A reads full OBD-II data (including SAE J1939 CANBUS and common protocols) and reports RPM, speed, engine coolant temperature, fuel level and fuel consumption. An onboard immobilizer (engine-cut) output, Bluetooth 2.0 for peripherals, FOTA firmware updates and robust motion sensing make the device a compact, high-value GPS tracker for Green-Gps-powered solutions.
Key Highlights
- Green-Gps compatible plug-and-play OBD-II GPS tracker for quick deployment and centralised fleet management.
- Real-time tracking and detailed telemetry: reads RPM, speed, coolant temp, fuel level and fuel consumption via OBD-II/CAN.
- Onboard immobilizer (engine-cut) digital output for anti-theft response and remote vehicle disablement when integrated with Green-Gps controls.
- Integrated GPS/GLONASS (u‑blox MAX‑7) with internal high-gain antenna and AssistNow A‑GPS for fast TTFF even when hidden.
- Bluetooth 2.0 enables pairing with compatible sensors or accessories to extend telemetry and condition monitoring.
- Driver behavior and safety analytics using a 3-axis accelerometer (harsh braking/acceleration, cornering and more) plus geo-fencing options.
- FOTA firmware updates and auto APN/time zone detection streamline large-scale fleet rollouts and maintenance.
How It Works with Green-Gps
When connected to Green-Gps, the T373A streams location and vehicle telemetry to the Green-Gps platform where data is normalized, visualized and actioned. Green-Gps ingests OBD-II parameters, diagnostic trouble codes, accelerometer events and GPS positions to deliver live maps, alerts and reports tailored for fleet management, anti-theft workflows and insurance telematics. Integration is straightforward: the T373A communicates over cellular networks and supports remote firmware management so device behavior can be adjusted centrally from Green-Gps.
- Real-time location and telemetry updates (GPS/GLONASS coordinates, speed, heading).
- OBD-II live data and Diagnostic Trouble Codes (DTC) for maintenance and fault detection.
- Fuel monitoring and fuel consumption reporting captured directly from the vehicle network.
- Remote immobilizer / engine-cut control via the digital output when enabled by Green-Gps policies.
- Bluetooth sensor support for expanded telemetry (temperature, BLE beacons) and accessory pairing.
- Driver behaviour events and geofence breach alerts (circle, rectangle, polygon).
