Designing a micro GPS tracking device
could anyone give me some insight to how complex the process of designing a very small GPS tracker which could be used to track lets say a person, which can post its co-ords to map software which is custom programmed etc in realtime.
1) Tracking someone who is on the move outdoors, only has very small pockets to fit the thing in.
2) The device must send co-ords to mapping software on a computer every 10 seconds maybe.
3) Someone can view there position on the map software in instantly to understand their exact position.
Also how expensive would the whole process cost to manufacturer roughly?
Thanks in advance and sorry for the vagueness in my question
