The GSP-1720 satellite data and voice module enables full two-way data and voice transfer, allowing the development of new and creative tracking and monitor & control applications 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.

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. GSP1720 Brochure
