Simplex Modems: Transmitter Unit (STU)

The Globalstar Simplex Modem or Simplex Transmitter Unit (STU) is designed to deliver reliable digital data communications for remote sensing and monitoring applications. The STU is a low cost, simplex device that allows packet-switched data to be sent automatically (on a time or event driven basis) from remote locations where alternative communications systems are unavailable or prohibitively expensive. The unit can monitor a wide range of assets including liquid petroleum gas (LPG) tanks, water tanks, pipelines, electricity meters and sea or land containers.

The STU is provided on an OEM basis and can be easily incorporated into a remote data solution. To integrate this product, please review the Globalstar OEM Certification Process.
