Satellite hybrid solution integrates satellite, GSM and GPS modules.
STG H680
Satellite-GSM-GPS Hybrid Tracking Unit functions as a continuous remote management device of fixed and mobile assets anywhere across the world. The STG H680 communicates with its server via the GSM/GPRS network or using a satellite modem when the GSM/GPRS network is unavailable.
The STG H680 unit stays in active GSM/GPRS communication when it is in range of cellular coverage. Satellite communication with its server is automatically activated whenever the STG H680 tracker is not in range of GSM/GPRS coverage.
Once an asset (e.g. boat, vessel, vehicle, etc.) is equipped with the STG H680 Satellite-GSM-GPS hybrid tracking unit, users can monitor and manage the asset using messages and location data provided by the LEO satellite modem integrated module covering all terrestrial and aquatic areas (e.g. oceans, lakes, remote mining sites) of the world.
The STG H680 dual communication function is illustrated as below.

Key Features
- Continuous real-time tracking in areas without cellular coverage
- Lower communication costs compared to using only satellite transmission
- An ideal hybrid (Satellite-GSM-GPS) tracker for boats (at sea, lakes) and mining / construction sites
Satellite Modem
- Satellite Modem: currently use Orbcomm OG2 modem
