I went back to my vet today to do some more research on the "GPS" chip but it turns out it is just another microchip without GPS capabilities. The poster was very deceiving though. It would be nice if someone would come out with one though.

My friend, I am an electrical engineer with experience in this area. Let me summarize by saying that a GPS that is "injectable" the way ID microchips are today is not feasible with current or near-term technology.

Most are collar attachments but I bet there will soon be a nicro chip out that does it too. Size is what is killing it now.

Greg I am glad that there is someone with some actual knowledge in this area. In your expert opinion why hasn't there been something like this yet? It seems with all the recent advances in technology something like this would be available soon.

A microchip ID is very simple and it is powered by the actual RF energy of the scanner as it goes over it.

A GPS is much, much (, much, much, much) more sophisticated than a microchip ID. It can get smaller, but I doubt it will ever be made as small as an ID microchip which, even with a robust coating is the size of a grain of rice.

To be useful as a locating device, the GPS unit has to receive GPS signals, then transmit them to a receiver that you have. Receiving is one thing, my friend, transmitting is entirely another.

To both receive and transmit is like a Walkie Talkie except that it is continuously transmitting. Ever use a Walkie Talkie? How often do you have to replace the batteries? How big were they? Want to put that in your dog? Want to do surgery and replace them that often?

Technology is really cool. We're making huge strides. But, because we're making huge strides in some areas doesn't mean that we're not hitting at least temporary hard stops in basic physics in others.

Greg,

That makes sense. I didn't realize the ID chips were powered by the scanners. Those Doggie AA Batteries would probably get pretty expensive

The links I posted said that in laymans terms

can put one on a collar tho and use it for this purpose.
and use it on multiple dogs. Sorry if I didnt explain that to you. Thought you would have read the links.........
