The GV350MG is a compact LTE Advanced vehicle tracker designed for professional fleet management, cold chain logistics and transportation monitoring. Plaspy compatible out of the box, the GV350MG brings reliable real-time tracking, robust CAN bus integration and extensive telematics to commercial vehicles worldwide, with LTE Cat M1/NB1 connectivity and 2G fallback for continuous coverage.
The unit combines a high-sensitivity u-blox GNSS receiver, full CAN 2.0A/B and SAE J1939 support, RS232 ports and multiple I/O to collect location, engine and sensor telemetry. When paired with Plaspy, the GV350MG delivers timely alerts, geo-fence enforcement, driving behaviour data and local buffering for up to 10,000 messages — all essential for scalable fleet management, anti-theft protection and fuel monitoring workflows.
Key Highlights
- Plaspy compatible: seamless real-time tracking and telematics integration via TCP/UDP/SMS transport and scheduled reporting.
- Global LTE Cat M1 & NB1 with EGPRS (2G) fallback for broad coverage and improved connectivity resilience.
- High-sensitivity u-blox GNSS (tracking −162 dBm) with position accuracy <2.5 m CEP for precise location services.
- Full vehicle integration: CAN 2.0A/B and SAE J1939, two RS232 ports, multiple digital I/O and latched output for ignition and alarm monitoring.
- Built for commercial fleets: wide 8–32 V DC range, 250 mAh backup battery and operating temperature −30 °C to +80 °C.
- Advanced telemetry features: geo-fence alarms, tow and crash detection, driving behaviour monitoring and support for dual fuel sensors.
- Accessory-ready: supports 1-wire temperature channels, external cameras, Garmin FMI and I/O extenders for customized deployments.
How It Works with Plaspy
Plaspy ingests the GV350MG’s location and vehicle telemetry to provide a unified dashboard, alerting and reporting system. The device continuously reports GNSS fixes, CAN bus parameters and input/output events to Plaspy using secure TCP/UDP or SMS transport. Plaspy then applies rules for geo-fences, scheduled reports and alarms, enabling real-time operational control and historical analysis for fleet management and cold chain logistics.
- Real-time location and telemetry updates: GNSS position, speed, heading and timestamped CAN data flow to Plaspy for live tracking and replay.
- Ignition and alarm status: configurable digital inputs deliver ignition, door or alarm events to Plaspy for route and security workflows.
- Fuel monitoring: support for dual fuel sensors provides fuel level telemetry to Plaspy for fuel monitoring and theft detection.
- Remote immobilizer capability: OTA control of digital outputs enables remote immobilizer or engine disable functions when configured.
- Bluetooth sensors: the GV350MG is optimized for wired vehicle integrations and 1-wire sensors; Bluetooth peripherals can be used via external gateways where required (no built-in BLE).
