G120 Features

High Precision GPS

GPS and GLONASS positioning systems are used simultaneously with a 72 channel high sensitivity receiver (-167dBm) for enhanced accuracy and faster fixes.

Real-Time Tracking

The G120 remains continuously connected while on the move for real-time asset tracking.

Bluetooth® Gateway

Bluetooth® 5.0 Gateway for affordable tagged asset management and sensor monitoring applications.

Out-of-Coverage Tracking

Fit the G120 with an optional Iridium Edge® Module to track assets in remote areas outside of cellular coverage.

Customizable Inputs / Outputs

Interface with a range of devices and switches to fit any application including seatbelt detection, duress and panic buttons, lights, in-cab warning buzzers, pulse counting, and more.

Remote Immobilization

Digital outputs can be connected to a relay to enable remote immobilization of vehicles in the case of theft, abuse, or unauthorized usage.

Theft Recovery

Switch to Recovery Mode in the case of theft or loss to activate live-tracking at 30 second intervals for asset retrieval.

Driver ID Options

Configure iButton®, RFID Readers, or Wiegand for Driver ID, Access Control, and Logbooking.

Driver Safety & Behavior

Monitor speeding, harsh acceleration, braking, cornering, idling, and more to improve safety and prevent unnecessary wear on vehicles.

Accident & Rollover Detection

Configure accident and rollover alerts triggered by extreme changes in velocity and orientation of vehicles.

Remote Worker Safety

Interface a variety of duress pendants to enable man-down alerts for lone and remote worker safety monitoring.

Run Hour Monitoring

Calculate run hours and distance travelled (odometer) to understand and optimize asset utilization.

Designed for Fleets of the Future

Fleet Management

Capture and analyze critical data points to improve and optimize fleet management strategies

Bluetooth® Gateway

Monitor vital vehicle components, reduce fuel consumption and theft, and more with wireless Bluetooth® sensors.

Driver ID

Configure iButton®, RFID Readers, or Wiegand for driver ID. Existing employee access badges or ID cards that support Wiegand may also be used.

Driver Safety & Behavior

Promote safe driving and meet compliance with real-time speeding, harsh driving, accident and duress alerts, and more.

Out-of-Coverage Tracking

Maintain real-time tracking even when assets roam out of cellular coverage with an optional Iridium Edge® Module.

Remote Worker Safety

Interface a variety of duress pendants to enable man-down alerts for lone and remote worker safety monitoring, even when out of cellular coverage.

Theft Recovery

Configure timely movement alerts and quickly switch to Recovery Mode to assist in theft recovery.


The G120 is capable of acting as an intermediate between a server and an RS232 serial connected device, passing and logging data received.
