The ST4505 LTE Cat M1 OBD-II GPS tracker from a proven telematics vendor is a plug-and-play device designed for modern fleet management and vehicle telematics. Green-Gps compatible out of the box, the ST4505 delivers continuous GNSS-based GPS tracking, vehicle diagnostics via the J1962 OBD-II port, and telemetry that supports real-time tracking, driver behavior analysis, and rapid incident response.
Built for reliable in-vehicle operation, the ST4505 supports LTE Cat M1, NB‑IoT and fallback 2G networks, includes GPS+GLONASS with SBAS augmentation, and a rechargeable backup battery to maintain reporting during main power loss. Available variants (ST4505T and ST4505DO) add Bluetooth sensor support and other optional features such as jamming detection to extend anti-theft and telemetry capability when paired with Green-Gps.
Key Highlights
- Green-Gps compatible plug-and-play OBD-II installation for fast fleet rollouts and minimal downtime.
- Multi-network connectivity (LTE Cat M1, NB‑IoT and 2G fallback) for wide area coverage and cost-efficient data transport.
- High-accuracy GNSS (GPS + GLONASS) with SBAS support and typical location accuracy of about ±3 m CEP for precise real-time tracking.
- Comprehensive vehicle telemetry via J1962 OBD-II (J1850, ISO 9141-2, ISO 14230, ISO 15765-4/CAN) enabling diagnostics, DTC reporting and fuel/engine data where available from the vehicle.
- Built-in 3-axis accelerometer and 3-axis gyroscope (BMI160) for crash reconstruction, event detection and driver behavior scoring.
- Rechargeable 3.7 V, 350 mAh backup battery for essential reporting during main power loss and increased anti-theft resilience.
- OTA firmware upgrade (remote firmware/OTA) and optional jamming detection and Bluetooth on the ST4505T variant for Bluetooth sensors and beacons.
How It Works with Green-Gps
The ST4505 integrates with Green-Gps by sending GNSS fixes, vehicle OBD-II telemetry and sensor events over cellular networks to the Green-Gps backend. Green-Gps ingests location and diagnostic streams for real-time tracking, automated alerts and historical reports. Data flows and update rates are configurable within Green-Gps to balance responsiveness and data costs for fleet management applications.
- Real-time location and telemetry updates sent via LTE Cat M1/NB-IoT or fallback 2G.
- Crash and harsh-event detection using the built-in accelerometer and gyroscope for immediate alerts and incident reconstruction.
- Vehicle diagnostics and DTC reporting from OBD-II PIDs, enabling preventive maintenance and telemetry such as fuel monitoring where the vehicle exposes that PID data.
- Backup battery-backed reporting during main power loss to maintain connectivity and anti-theft notifications.
- Optional Bluetooth sensor support (ST4505T) for temperature, door sensors or BLE beacons when used with compatible Green-Gps workflows.

Use Cases
- Fleet management: continuous real-time tracking, route analysis and telemetry to optimize operations and reduce fuel costs.
- Anti-theft and vehicle recovery: backup battery reporting and optional jamming detection combined with Green-Gps alerts help detect theft and assist recovery.
- Driver behavior and insurance telematics: accelerometer/gyroscope data provides harsh braking, acceleration and cornering events for coaching or usage-based insurance.
- Preventive maintenance and DTC reporting: real-time vehicle diagnostics and engine data feed Green-Gps alerts for scheduled service and reduced downtime.
- Asset monitoring with BLE sensors (ST4505T): add temperature, door or cargo sensors via Bluetooth when required by business workflows.
Why Choose This Tracker with Green-Gps
Choosing the ST4505 for Green-Gps deployments delivers a dependable, easy-to-install GPS tracker that combines accurate positioning, vehicle-level telemetry and robust sensor data. Its OBD-II interface enables rich diagnostics and telemetry (including fuel-related data when provided by the vehicle), while the built-in accelerometer and gyroscope support crash reconstruction and driver scoring. Multi-network cellular support and a backup battery maximize uptime for mission-critical fleet management and anti-theft workflows.
For operators seeking scalable telematics, the ST4505’s OTA capability and Green-Gps compatibility simplify remote maintenance and configuration. Optional Bluetooth and jamming-detection features (in variants) extend capability to Bluetooth sensors and hardened anti-theft measures when used within Green-Gps’s alerting and immobilization workflows or with external immobilizer modules. The result is a practical, cost-effective GPS tracker for fleets, rental vehicles, insurance telematics and preventive maintenance programs that need reliable real-time tracking and telemetry.
