Which MCU and COmpiler are you using ? What Fosc are you using ?
 

it might be the coordinates of the gps modem's position on earth. some modems provide it in degree, minutes, and seconds. you need to check the Skylab website or data sheet of the modem for this.
Hope this could help.
 

The beginning of each GPS NMEA sentence is preceded by a code/tag which indicates the purpose of the data which follows:

GPS - NMEA sentence information

The NMEA code/tag which indicates required sentence containing date and time data is $GPZDA.

You may need to enable this feature of the particular GPS module you are utilizing.
