The VL502 OBDII GNSS vehicle tracker is a Plaspy compatible GPS tracker built for corporate fleets, usage-based insurance (UBI) programs, dealer monitoring and individual vehicle oversight. This compact plug-and-play OBDII unit delivers real vehicle telemetry — VIN, engine speed, coolant temperature, accumulated mileage, fuel consumption stats, battery voltage and ACC/ignition status — over 4G LTE with 2G fallback, enabling fast, reliable real-time tracking and fleet management through the Plaspy platform.
Designed for quick installation and robust day-to-day operation, the VL502 combines dual GNSS positioning (GPS + BDS) with a built-in accelerometer and support for common onboard diagnostic protocols (K-Line and CAN bus). When paired with Plaspy, the VL502 provides the telemetry and event data needed for anti-theft alerts, driver behavior reporting, fuel monitoring and operational optimization without complex wiring or prolonged setup.
Key Highlights
- Plug-and-play OBDII installation for fast deployment across vehicle fleets.
- Plaspy compatible for seamless real-time tracking and centralized fleet management.
- Rich vehicle telemetry: VIN, engine speed, coolant temperature, mileage, fuel consumption and battery voltage.
- 4G LTE communication with 2G GSM fallback and multiple regional band variants for broad coverage.
- Dual GNSS (GPS & BDS) with high accuracy (<2.5 m CEP) and fast time-to-first-fix.
- Built-in accelerometer for driving behavior detection (over-speed, harsh braking/acceleration/cornering, collision).
- Compact, rugged form factor suitable for demanding vehicle environments and long operating temperature range.
- Supports standard OBD protocols (ISO 9141-2, ISO 14230-4 KWP, ISO 15765-4 CAN, SAE J1939) for accurate diagnostics and fault code retrieval.
How It Works with Plaspy
The VL502 sends GNSS positions and OBDII-sourced telemetry to Plaspy over LTE (with automatic 2G fallback), where that data is processed into live maps, alerts, and reports. Plaspy ingests the device’s diagnostic parameters and event signals to enable real-time tracking, predictive analytics and configurable notifications for fleet managers and insurance telematics teams.
- Real-time location and telemetry updates delivered to Plaspy for live tracking and historical playback.
- VIN, engine speed and diagnostic trouble codes (DTCs) for maintenance scheduling and remote diagnostics.
- Fuel consumption and accumulated mileage reporting to support fuel monitoring and UBI calculations.
- Ignition/ACC status, engine idling and device removal events for operational and anti-theft alerts.
- Driving behavior and accelerometer events (over-speed, collision, harsh acceleration/braking/cornering) for safety scoring and driver coaching.
