Data Format of GPS Module

K2DGR8 · Sep 24, 2011

What is the Data Format of a GPS Module, connected serially to 8051?
The o/p of GPS consists of many more data. But I want only Lat./Long. information from it.
How can I do it?

K2DGR8,

It depends on the module, but most current ones support standard NMEA183 output. You'll set up the GPS to output the
sentence of your choice (for instance, for lat/long, you would pick the GGA or RMC sentences). From there it's just a matter
of reading in the string and parsing it in your 8051, picking out the lat/long data).

Here is an example of the data you'll be dealing with, in this case using the RMC string:

$GPRMC,123519,A,4807.038,N,01131.000,E,022.4,084.4,230394,003.1,W*6A

Where:
RMC---------------------------Recommended Minimum sentence C
123519------------------------Fix taken at 12:35:19 UTC
A------------------------------Status A=active or V=Void.
4807.038,N--------------------Latitude 48 deg 07.038' N
01131.000,E-------------------Longitude 11 deg 31.000' E
022.4--------------------------Speed over the ground in knots
084.4--------------------------Track angle in degrees True
230394-------------------------Date - 23rd of March 1994
003.1,W------------------------Magnetic Variation
*6A----------------------------The checksum data, always begins with *
