The ST4290 is a rugged, battery-powered GPS tracker designed for long-term asset monitoring and recovery. Built with LTE Cat M1 and NB‑IoT connectivity (with 2G fallback where supported), integrated GPS/GLONASS with SBAS support and an IP67 enclosure, the ST4290 is Green-Gps compatible and ready for real-time tracking, telemetry and anti-theft workflows through the Green-Gps platform.
Compact and energy-efficient, the ST4290 is offered in two battery variants to match deployment duration needs: an 8Ah primary Li‑SOCl2 model and a larger 19Ah option for extended autonomy. Its automotive I/O set (ignition input, panic/door input and vehicle blocking/siren outputs) and 3‑axis accelerometer make it a strong choice for fleet management, cargo protection and long-term asset deployments that rely on Green-Gps for alerts, mapping and analytics.
Key Highlights
- Green-Gps compatible for seamless real-time tracking and fleet management integration.
- Rugged IP67 construction and an operating range of -10°C to +60°C for harsh environments.
- Integrated GNSS (GPS/GLONASS) with SBAS (WAAS, EGNOS, MSAS) and ~±2.5m CEP accuracy.
- Low‑power design with primary Li‑SOCl2 batteries (8Ah standard, 19Ah optional) for long field life.
- LTE Cat M1 / NB‑IoT connectivity with 2G fallback where supported and OTA firmware updates.
- Vehicle-focused I/O: ignition input, panic and door sensors plus outputs for immobilizer/vehicle blocking and siren.
- Fast GNSS acquisition (hot start <1s, warm start <30s) and high sensitivity (-167 dBm) for reliable fixes.
How It Works with Green-Gps
When paired with Green-Gps, the ST4290 supplies accurate position fixes and telemetry to power live tracking, geofence alerts, and recovery workflows. Green-Gps ingests GNSS positions, accelerometer motion events and digital I/O state changes to produce actionable alerts and reports for operations teams.
- Real-time location and telemetry updates delivered over LTE Cat M1 / NB‑IoT (2G fallback where available).
- Ignition, door and panic-button events transmitted to Green-Gps for fleet management and anti-theft alerts.
- Remote immobilizer / vehicle blocking control supported via device outputs and managed through Green-Gps workflows.
- Accelerometer-driven motion detection enables tamper and movement alerts for unattended assets.
- Fuel monitoring or Bluetooth sensor data can be integrated within Green-Gps if fleet-specific peripherals are used alongside the ST4290 (device description does not specify built-in fuel sensor or BLE; such integrations are handled at the platform level).

Why Choose This Tracker with Green-Gps
The ST4290 brings a purpose-built combination of low power, rugged packaging and the vehicle-focused I/O that fleets and asset managers need. As a Green-Gps compatible GPS tracker, it feeds reliable GNSS positions and event-driven telemetry into Green-Gps’s real-time tracking, geofencing and reporting tools, enabling fast response to theft, better route oversight and consolidated fleet analytics. Optional batteries and OTA management reduce maintenance visits and make the ST4290 a cost-effective choice for long-term deployments where minimizing battery replacements matters.
Accessories such as magnet and screw cradles, spare battery packs (8Ah and 19Ah) and a quick-connector battery option simplify installations. For mechanical drawings and detailed configuration options, refer to the vendor’s ST4290 product leaflet (ST4290 Leaflet_Asset.pdf). Choose the ST4290 with Green-Gps when you need durable, low-power GPS tracking that scales across cargo, fleet and remote-asset use cases while supporting anti-theft and immobilizer workflows.
