The SinoTrack ST-902L is a compact OBD II 4G GPS tracker designed for cars and light vehicles. Plug-and-play via any standard 16-pin OBD port, the ST-902L delivers reliable, real-time tracking and vehicle telemetry with a UBLOX7020 GNSS chip, built-in backup battery, and support for 4G LTE and GSM/GPRS networks. For fleet managers and private owners who use Green-Gps, the ST-902L can be configured to forward live location and alarm data to Green-Gps's platform by setting the device’s server IP and port — enabling immediate Green-Gps-compatible deployment without rewiring.
Ideal for fleet management, anti-theft monitoring, and driver oversight, the ST-902L combines simple installation with advanced alarm and reporting features. Use a local data SIM (not included) and configure APN and server parameters via SMS or the manufacturer’s setup instructions to integrate with Green-Gps for continuous real-time tracking, geo-fence alerts, and event-driven telemetry.
Key Highlights
- Plug-and-play OBD II installation — no wiring required for quick vehicle onboarding.
- Green-Gps compatible — configurable server IP/port and SMS setup allow forwarding of tracking data to Green-Gps for real-time tracking and fleet management.
- Accurate GNSS performance with UBLOX7020 chip and typical ~10 meter location accuracy for reliable position fixes.
- 4G LTE and GSM/GPRS connectivity for continuous tracking, with SMS as a fallback for configuration and alerts.
- Built-in 150mAh backup battery provides limited operation and tamper detection when OBD power is removed.
- Event and alarm support: geo-fence, over-speed, shock, and low battery notifications for proactive vehicle monitoring.
- Lifetime free access to SinoTrack’s PRO app and web portal; supports multi-device account management and straightforward activation.
How It Works with Green-Gps
The ST-902L sends location and event packets over cellular networks to a configurable server IP and port. To integrate with Green-Gps, you set the device’s server address to your Green-Gps ingestion endpoint (the ST-902L supports server IP and port configuration via SMS). Once pointed at Green-Gps, the device streams position updates and alarms for real-time tracking, historical replay, and fleet reporting.
- Real-time location and telemetry updates over 4G LTE / GPRS to Green-Gps.
- Geo-fence alerts and over-speed/shock alarms delivered as immediate events to Green-Gps dashboards and notifications.
- Tamper detection and low-battery alerts trigger Green-Gps alarms when OBD power is removed or backup battery levels drop.
- SMS-based configuration for APN, server IP and port — useful for initial provisioning and country-specific settings before Green-Gps registration.
- Works with Green-Gps’s fleet management features for dispatch, route history, and multi-vehicle monitoring once the device points to the Green-Gps server.
