Do you have a question ?

I suspect you're having problems processing gps text strings. Please read:

4

No I just want to share my code to you

5

Was this the subject of a previous thread? If so, then please post it there, as a followup.
Otherwise, perhaps it should go to showcase, though for that it should have at minimum a complete schematic, and textual description.
