Globalstar Packet Data using the GSP1720 Modem. Real time duplex IP data services that support Packet Data across the Internet or private networks.

The GSP 1720 Satellite Data and Voice Module (SDVM) provides full, two way data and voice capability, allowing for the development of new and creative applications from basic AT Modems to fully featured fixed telephone services from remote locations.

The GSP 1720 can provide Direct Connect Internet, Dial up Internet or Remote Terminated Data sessions and asynchronous computer to computer connectivity for Supervisory Control and Data Acquisition (SCADA) applications. These options provide communication lines with land and marine-based equipment, while complementing mobile and stationary field solutions. Whether mobile or stationary, the GSP 1720 helps you monitor, control or track assets remotely through the Globalstar satellite network - affordably, reliably and with low-power requirements.
