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:
ⅷ $GPGGA
ⅷ $GPRMC
ⅷ $GPGSA
ⅷ $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 90.
How do I configure a GPS application to use my
GPS-capable device?
To configure a GPS application to use your GPS-capable device:
1. Start GPS NMEA (page 91).
2. Note the “GPS Port” value displayed in the expanded GPS Receiver window
(page 35).
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 89.
Note:
To ensure the best data performance of your USB modem, it’s recommended that
you not activate the NMEA stream unless you are going to use it.
