Is it possible to send full $GPGGA line via GSM?  :|

Yes, a full $GPGGA string is about 75 characters so you can use SMS, Email, FTP or what ever else you like.

Can you tell me a little bit more about what you are trying to do?

Sure. Your first project should have been about reading data from the GPS. That would have rated about a 3 on a scale of 0 to 10.

Your second project should have been about sending text messages and receiving responses. That would have rated about a 7 on a scale of 0 to 10.

This project is about combining those two projects. It rates a 0 on the 0 to 10 scale.

I would start by reviewing some of the code examples and libraries that you can find here.

Here is a GPS library. It takes most of the data from the $GPRMC string but it should have what you need. You could modify this code to use $GPGGA.

Or you could use a GPS library and this one works very well.

For transmitting over GSM here is a library you can try. I have never used this one but it is a place to start.
