A couple of thoughts:
Animal researchers have had a device like this for a while, it was
called a "Mortality Transmitter" it was designed to send a signal
if the device didn't move for so many hours. They were tagging
young moose and elk as I recall and discovered that black bears
were significantly more advanced predators than previously thought.
Even now the RBOC's are putting systems in place to locate cell
phones by triangulation (big brother mandate), add a few sensors
and viola!
I remember reading an article, I believe it was in WIRED, about an
Australian who was promoting data transmission of small packets to
low earth orbiting satelites for cattle tracking, remote monitoring
of water levels at remote sites, etc.

I read, and some fellow classmates and I experimented with devices
like this when we were in high school. We got the idea from an
article in Scientific American's Amateur Scientist's column. It was
a how-to complete with drawings and schematics. I very distinctly
remember the warning to let the epoxy coating cure thoroughly to
prevent gastrointestinal irritation ;) . This article would have
appeared in 1975 or earlier.
