so far all examples are strictly as a set message and obviously with a moving gps signal each sms would be unique
You could use sprintf() or similar to produce a URL string containing variable parameters into a character array, and then send that in the same way as the examples you have already seen to send URLs defined as a hard-coded string. To make sure you've got the idea, you can test that by printing the content of the character array over the serial port.
