Developing Modem Applications

Position Location Determination

The GSP-1620 modem has a “get position” AT command, AT$QCPLS, that provides a latitude and longitude location as well as a confidence value.

This command has a parameter to select between getting the current position (via making a new request) or returning the last stored position:

•If you select the current position and you are NOT in a call, the modem returns “ERROR.”

•If you select the stored position and there is no stored position (you have never done a position request), the modem returns “ERROR.”

Using Packet Data

 

Globalstar and the GSP-1620 modem offer direct Internet

 

connectivity by bridging the “last thousand mile” air gap

 

using LEO satellites. This section details the capabilities

 

offered by the GSP-1620 modem for user connectivity and

 

packet data transmission.

 

The GSP-1620 modem lets the application device (DTE)

 

connected to the modem originate or receive a “packet data

 

call.” It establishes a PPP session, connects to the Internet,

 

and then establishes a session with a host application at the

 

remote end.

Note

For a comparison of packet and asynchronous data, see Table 5-1 on

 

page 5-4. For information about asynchronous data service, see Using

 

Asynchronous Data on page 5-30.
