I am interested in creating an inexpensive gps tracking device in the developing world. H

How difficult would it be to create a gps device which sends its location every so often as an sms? Is there a protocol which would be easier?


To receive the messages, I have a gsm modem attached to a computer with the handling software and my plan is to modify the software to show where users are on a live map.

This could be a good start. http://ohararp.com/blog look for Twitter Tracker.

that looks good! this is my first foray into embedded design/implementation so I probably wont find it quite as easy as you did

SMS is text messaging over a cell phone.

GPS is global positioning.
