The GSP-1720 satellite data and voice module enables full two-way data and voice capability, allowing the development of new and creative applications from basic AT Modems to full-featured fixed telephone service for remote areas. For Supervisory Control and Data Acquisition (SCADA) applications, the GSP-1720 Satellite Data/Voice Module (SDVM) can provide either Direct or Dial-up Internet as well as asynchronous computer to computer connectivity. These options provide communications with land and marine-based equipment, while complementing mobile and stationary field solutions. Mobile or stationary, the GSP-1720 helps you monitor, control or track assets remotely through the Globalstar satellite network – affordably and with low-power requirements. It’. Designed for multiple applications, the GSP-1720 Module offers a flexible solution for the Original Equipment Manufacturer (OEM), as well as providing a developer's kit for accelerated time to market. |

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. |
