interfaces facilitate ease of use and OEM application
integration.
• The SCADA application serves as the DTE (data
terminating equipment, or terminal) at the remote site,
communicating with software in the modem through AT
commands sent to either the modem’s Control or Data
ports.
• Data flows to and from the modem over-the-air, using the
Globalstar satellites and Gateways connected to the
Internet (for packet data) or to the PSTN (for
asynchronous data).
• OEMs provide the host application (server), which
communicates with the remote SCADA application (DTE)
to manage the field processing of data and reports process
exceptions, performance reports, alarm conditions—in
short, any data needed from the remote site.
Note
QUALCOMM offers a GSP-1620 Modem Integrator’s Kit (MIK) to assist
OEMs in developing user applications for GSP-1620 Satellite Data
Modems, as described in Chapter 8, Modem Integrator’s Kit.
Typical Modem SCADA Applications
In remote settings or difficult-to-access sites, acquiring and
responding to process control and alarm data can be
challenging and costly. For both system integrators and
OEMs, the QUALCOMM Globalstar GSP-1620 Satellite Data
Modem provides real-time, low cost, bi-directional data
communication solution applications in remote locations for
fixed or mobile use.
The GSP-1620 modem lets you retrieve data automatically
from remote sites, such as power substations,
telecommunication concentration nodes, oil and gas wells,
pipes, and offshore facilities. Unmanned sensors connected to
the GSP-1620 modem can monitor remote operations and
initiate alert notifications.
