The T303 vehicle GPS tracker is a professional-grade telematics device designed for fleet management, anti-theft protection and driver behaviour monitoring. Plaspy-compatible out of the box, the T303 brings reliable real-time tracking, configurable geo-fencing and remote immobilization options to organisations that need accurate location, safety alerts and up-to-date telemetry for vehicles of any size.
The T303 builds on the proven T301 platform and adds a u-blox 6M GNSS module, quad-band GSM/GPRS, FOTA support and a comprehensive set of inputs and outputs for ignition detection, engine control and sensor telemetry. When paired with Plaspy, the T303 delivers actionable reports, live tracking and emergency alerts that simplify fleet operations, anti-theft workflows and driver profiling.
Key Highlights
- Plaspy compatible for seamless integration into real-time tracking and fleet management dashboards.
- Quad-band GSM with GPRS class 12 ensures wide cellular coverage for consistent telematics data.
- u-blox 6M GNSS chipset with A-GPS delivers high-sensitivity positioning and sub-3 m accuracy in typical conditions.
- Internal immobilizer and a digital engine-control output support remote immobilization and anti-theft workflows.
- Multiple tracking modes (time, distance, course, status) and configurable geo-fences (circle, rectangle, polygon).
- Built-in 3-axis accelerometer and seven types of driver behaviour detection for safety and driver profiling.
- Analog input for fuel or temperature sensors plus vehicle battery monitoring for telemetry and fuel monitoring use cases.
- FOTA (firmware update over GPRS), auto APN and time zone identification for reduced maintenance overhead.
How It Works with Plaspy
Connecting the T303 to Plaspy is designed to be straightforward: the device transmits GNSS fixes and telemetry over GPRS while Plaspy ingests the data stream, applies rules, and surfaces real-time location, alarms and reports. Plaspy's platform interprets T303 events (ACC, SOS, immobilizer, geo-fence breaches and driver behaviour alerts) so fleet managers receive timely notifications and can act immediately.
- Real-time location and telemetry updates — GNSS positions and vehicle telemetry streamed over GPRS for live maps and history playback.
- Ignition (ACC) detection and engine status — ACC input enables trip segmentation and ignition-based reports.
- SOS button emergency alerts — immediate notification in Plaspy when SOS is triggered.
- Remote immobilizer / engine cut — use the device’s digital output under Plaspy control for anti-theft immobilization workflows.
- Fuel monitoring and analog sensors — analogue input supports fuel or temperature probes for telemetry and fuel monitoring dashboards.
- Driver behaviour and safety events — seven built-in behaviour detections plus accelerometer readings feed Plaspy’s driver scoring and alerts.
