GPS/GSM Based Project

Global Positioning System
Started to develop GPS/GSM project
I purchased one GPS unit and GSM/GPRS modem for this project.
ARM7 (LPC2148) processor (Blue Board) board is using for this project.
GPS data receiving side is ok, position data is getting in NMEA format(ascii text).
In the first stage , I use this data for  maping in Google earth.
GPS receiver data out is in UART (TTL3.3v) communication.
Data received from GPS via UART conected to ARM through UART0.
Processed data fed to the PC via BlueBoard's UART1.
But my laptop having only USB.
This problem solved by RS232 to USB convertor.
GPS data to be linked to the Google Earth by any bridge software (earthbridge).
Now the position showing in google earth according to gps data.
In google Earth we can save the track,map,trip etc in XML formal and can be share with others by email.

National Marine Electronics AssociationNMEA has developed a specification that defines the interface between various pieces of marine electronic equipment. The standard permits marine electronics to send information to computers and to other marine equipment
