Added a "real" GPS-sensor

Hi,
I wrote an "extended" GPS-sensor. The Geodetic coordinates for the Blender origin are stored in the properties. As it computes the current position in Blender and sends a point in Geodetic coordinates back. I described in a document (66.4kb PDF) the different steps, conversions and transformations with sources(!) more in detail, so that it gets (hopefully) clear and comprehensible. How should I distribute it? Should I send a mail with it attached? 
I just named it "real_gps", but I am not very happy with this name. So I would be very grateful for any suggestions for a good name. 
Pylint tells me that in few cases the lines are too long, but I do not think that a linefeed would be more beneficial. 
In the next few days small changes could be still made (e.g. changing the message to get closer to a real sensor).
Any advice and comments are welcome to improve the code.
