GPS data RMC GSr

I set up the server to trace the data sent from GPS device. And the output is:

GET /tr206.php?RMC=GSr,354660042186281,4,5,00,,3,011313,031703,E10538.9146,N1846.2847,5,20.28,340,10,0.7,91*5b! HTTP/1.1

Could you please help me to understand what are the values meaning?

Your ouput is a RMC sentence defined in NMEA 0183.

RMC=GSr,354660042186281,4,5,00,,3,011313,031703,E10538.9146,N1846.2847,5,20.28,340,10,0.7,91*5b

But it has some extensions, like "GSr", which is not a pure RMC format. So for reverse engineering you should start on the end of the string "*5b" which is the RMC checksum, and work to the begin of the line:

This is longitude: E10538.9146
This is latitide: N1846.2847

for more info search for NMEA format description.
For example here RMC,
or better here where you find the description of the format of the latitude and longitude coordinates.
