The GVT800 (GVT-800) by Megastek is a Plaspy compatible 4G LTE GPS tracker built for heavy-duty vehicles, intercity and school buses, and commercial fleet management. Combining a high-sensitivity Ublox GNSS module with multi-network cellular communications, the GVT800 delivers reliable real-time tracking and telemetry for fleet operators who need robust position reporting, alarm handling, and remote control capabilities across long-haul and urban routes.
Designed for industrial environments, the GVT800 supports server uploads over UDP/TCP and can also provide quick SMS link location sharing for mobile viewing. With a wide input voltage range, a rechargeable 750 mAh backup battery, multiple I/O interfaces and a compact enclosure, this GPS tracker integrates into Plaspy to provide anti-theft workflows, fuel monitoring extensions, ignition/power event reporting and centralized fleet management.
Key Highlights
- Plaspy compatible for real-time tracking and centralized fleet management via UDP/TCP server integration.
- Multi-network cellular: 4G LTE/WCDMA/GSM quad-band connectivity for reliable coverage and telemetry uploads.
- High-sensitivity Ublox GNSS with <10 m position accuracy and fast hot/warm/cold start performance.
- Built-in 750 mAh rechargeable battery and wide DC 9–33V input for dependable backup and vehicle compatibility.
- Comprehensive alarm set including impact/knock, overspeed, GPS loss, external power disconnect and SOS emergency.
- Rich I/O: digital and analog inputs, multiple RS232/RS485 ports for CAN/device integration and remote engine/power cut control.
- Optional fuel level, temperature and camera integrations for advanced telemetry and fuel monitoring workflows.
How It Works with Plaspy
The GVT800 integrates with Plaspy by transmitting GPS position and telemetry to the Plaspy server using standard UDP or TCP transport. Plaspy ingests location updates, alarms and I/O events so fleet managers can view live vehicle locations, replay trips, and configure automated alerts for anti-theft and safety workflows.
- Real-time location and telemetry updates sent over 4G LTE/WCDMA/GSM using UDP/TCP to Plaspy servers.
- Alarms and status: impact/knock, overspeed, GPS loss, external power disconnect and internal battery low are forwarded to Plaspy for immediate alerting.
- Ignition/power events and digital input signals can be reported to Plaspy to trigger engine or operational logic.
- Remote immobilizer-style control: the unit supports remote engine (oil) and power cut commands which Plaspy can initiate when configured for anti-theft or emergency response.
- Fuel monitoring and sensors: optional capacitive/ultrasonic oil level and temperature sensors can be paired with the GVT800 and their telemetry displayed in Plaspy dashboards and reports.
