you might ask yourself what this project is for.
When I'm on holiday, I always wonder how far from my house I am, and also like to know the altitude at which I am etc...
And that's what this does; it tells you your latitude and longitude, the time (GMT), the altitude, and how far you are from your house. If you wanted, you could easily modify the code to tell you more like your speed and heading in degrees.

Finally, I would like to apologies for this entry, I find it very scruffy and unpolished.
I didn't have much time to do it, I have to work for school. If you have any question, please message me and I will take care to reply. Also, comment on what you would like to be added to this tutorial (such as a part you don't understand) and I will do my best to add it.
Again, I apologies.
Step 1: Hardware
The lcd is connected to an I2C/SPI "backpack" to reduce the amount of pins needed put you could do without it.
The Gps,shield and backpack come from Adafruit.com
The lcd and arduino from Sparkfun.com
Finally it is enclosed in a rather nice case : http://www.adafruit.com/index.php?main_page=product_info&cPath=17&products_id=271
Step 2: Software
You have to modify the lat/long to your house's one.
If you don't know your latitude and longitude, you can check out this website (http://itouchmap.com/latlong.html ).
If you have any enquiry, send me a message.
