GPS Message Syntax

Part 6 – AT Commands for GPS-Enabled Devices

Chapter 16 – AT Commands for GPS-Enabled Devices

GPS message syntax that is sent from the UIP device to the backend server:

<GPSPREFIX><GPSURAIS><NMEA_MESSAGE><CR><LF>

Where

<GPSPREFIX> is the unique prefix. Length is 0 to 4 characters (Character format or requirements usually provided by backend service)

<GPSURAIS> is the unique remote asset identification string. Length is 0 to 20 characters (This string may be provided by the backend service)

<NMEA_MESSAGE> is a standard NMEA sentence received from the internal GPS receiver <CR><LF> is a Carriage Return and a Line feed

The message that will be transmitted can be viewed with the #GPSGETMESSAGE command. The difference from the viewed message and the transmitted message will be the NMEA message parameters due to timestamp changes and or location changes.

The <GPSPREFIX><GPSURAIS><NMEA_MESSAGE><CR><LF> is a popular format used by numerous services. Along with the format, the following rules are followed:

Typical transmission protocol is UDP (format provided by backend service) due to low overhead, however TCP is available

Multiple GPS message can and will be transmitted granted the specific message type is enabled (GPSGPVTG, GPSGPRMC, etc)

Typical minimum message type needed by the backend services is usually the GPRMC or GPGGA and GPVTG messages (Requirement provided by the backend server)

Do not use the $ character in either the <GPSPREFIX> or <GPSURAIS> sections

Typical transmission intervals to the backend service are 5sec and greater (Requirement provided by backend server)

GPS Message Examples

The following examples use a <GPSPREFIX> configured to && and a <GPSURAIS> configured with ID1111

&&ID1111$GPGSA,A,3,07,09,11,20,28,31,,,,,,,3.0,2.2,2.1*36<CR><LF>

&&ID1111$GPGSV,3,1,09,04,40,193,41,07,79,354,50,08,02,171,00,09,28,305,31*78<CR><LF> &&ID1111$GPGSV,3,2,09,11,15,048,45,20,21,078,37,24,08,205,27,28,55,122,46*77<CR><LF> &&ID1111$GPGSV,3,3,09,31,67,052,43*43<CR><LF> &&ID1111$GPGGA,223750.00,4502.2467,N,09302.4844,W,1,05,5.4,287.0,M,-27.6,M,,*58<CR><LF> &&ID1111$GPRMC,223750.00,A,4502.2467,N,09302.4844,W,57.00,97.29,131104,2.5,E,A*20<CR><LF>
