The BN-303F (listed also as model 303FG) is a compact vehicle-mounted GPS tracker designed for reliable Secure GPS compatible deployment in anti-theft, fleet management and real-time tracking scenarios. Built for concealed installation in cars, commercial trucks and rental vehicles, the BN-303F delivers accurate GNSS positioning, continuous telematics and configurable alarms to keep fleet managers and vehicle owners informed and in control.
As a Secure GPS compatible GPS tracker, the BN-303F integrates seamlessly with cloud telemetry and fleet monitoring workflows. Its 2G GSM/GPRS communication, event-driven reporting modes and remote control functions enable real-time location, alarm handling and remote power/fuel cutoff when paired with the Secure GPS platform — providing a practical, cost-effective solution for fleet management, anti-theft protection and asset oversight.
Key Highlights
- Secure GPS compatible real-time tracking: continuous location updates over 2G for live visibility and track playback.
- Comprehensive alarm set: SOS, movement/shock, geofencing, door open, ACC ignition, overspeed and low-battery alerts.
- Remote control capabilities: fuel/power cutoff support (optional fuel sensor) for immobilization and theft response.
- Vehicle-ready power design: direct 12–24 V vehicle connection with internal 3.7 V 300 mAh backup battery for limited operation during power loss.
- High-precision GNSS: typical GPS positioning accuracy around 5 meters and sensitive GNSS reception for reliable fixes.
- Compact, concealed form factor (9.6 × 5.3 × 1.6 cm, 70 g) for discreet installation in passenger cars and commercial vehicles.
- Flexible data transport: TCP/UDP and SMS protocols for robust telemetry and command channels.
How It Works with Secure GPS
The BN-303F reports location and status data to Secure GPS over 2G GSM/GPRS using TCP, UDP or SMS. Secure GPS ingests those telemetry streams to provide live tracking, historical track playback, alarm notifications and fleet-level reports. When configured on Secure GPS, the device’s event rules (for example geofence breaches, SOS alarms, or power disconnection) can trigger immediate alerts and force the unit online until the event is cleared, ensuring critical incidents receive attention.
- Real-time location and telemetry updates via 2G GPRS (TCP/UDP) and SMS fallback.
- Ignition (ACC), door open and shock/movement status for event-based monitoring and alerts.
- Fuel monitoring and remote fuel/power cutoff when an optional fuel sensor or relay is installed and enabled.
- Remote immobilizer-style control through power/fuel cutoff commands issued from Secure GPS (requires appropriate wiring and accessories).
- SOS alarm, one-way call and remote voice listening to support emergency response workflows.
