What is a GPS application?
A GPS application is an application that uses NMEA data to get regular location coordinate updates and values typically displayed in an application. (For more information on NMEA, see “What is NMEA?” [below].)
Examples of GPS applications are Microsoft Streets & Trips, and Microsoft MapPoint.
What is NMEA?
NMEA stands for “National Marine Electronics Association.”
NMEA 0183 is a standard protocol used by GPS devices to send and receive data.
NMEA output is composed of various strings. Sprint GPS data cards support the following strings:
⬤$GPGGA
⬤$GPRMC
⬤$GPGSA
⬤$GPGSV
See also “When do I need to use NMEA?”, “How do I start and stop NMEA?”, and “How do I configure my NMEA port?”, starting on page 99.
How do I configure a GPS application to use my
To configure a GPS application to use your
1.Start GPS NMEA (page 100).
2.Note the “GPS Port” value displayed in the expanded GPS Receiver window (page 47).
3.Configure your GPS application to use the same port. For help, see the documentation of the GPS application.
When do I need to use NMEA?
You need to use NMEA only when using a GPS application that uses an NMEA output stream. For more information, see “What is a GPS application?” on page 99 and “How do I start and stop NMEA?” on page 100.
Note:
To ensure the best data performance of your card, it’s recommended that you not activate the NMEA stream unless you are going to use it.
