As some might recall, I almost lost my quad copter a few weeks ago. I was very, very lucky to find it just at the edge of some tall grass. Five more feet to the north and I'd never have found it.
So, I ordered a little (1"x1"x3/8") GPS tracking device. It has all sorts of bells and whistles. It calls you, it sends text messages. You can text it with queries for its location. You can view it in satellite or street view using a downloadable app. You can call it and it will make enough noise that you'll be able to find it from about 30 to 50 feet away. Attach it to the quad copter, and it should never get lost again. Above water, anyway.
It needs its own SIM to send and receive texts. Unfortunately, it doesn't like Apple products, so I had to download a half-baked Apple app for SMS texts. It sorta works. It will send and receive texts to and from my Blackberry. The GPS won't send certain texts to the iPad. It will send all texts to the Blackberry, and receive all. The Blackberry can receive texts with clickable links to the maps. The iPad will not.
So, I have to query the GPS for its location, copy the text link, email it to the iPad, open the email app on the iPad, then click on the link to open Safari to look at the map.
Blackberry, android, and Apple. Why can't we all get along?
