A popular GPS communication protocol is the one specified by NMEA (see here). Communication is done in "sentences", which start with $-- where -- is the talker ID.

Page 18 of the linked specifications gives a list of possible talked IDs. I cannot seem to be able to find the talker ID of my GPS receiver (the datasheet is available here). I expect that it is one of CR, GN, GS or SN, but I don't know for sure.

What is the talker ID of my GPS receiver.

[Note: I am writing test software for a board for which the components only arrive in about 1 month.]

  • \$\begingroup\$ Have you asked the manufacturer? You could ask for a sample NMEA output log... Or just wait a month :) \$\endgroup\$ – Justin Apr 27 '12 at 14:34

NMEA is used to connect several kinds of marine equipment with a PC, GPS is just one of these. GPS receivers should identify themselves as "GP". (GLONASS has "GL" as talker ID.)

Example GGA sentence:

$GPGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47
