Well, the way it would work (and I'm sure how the TAGG does it) would be to leave the GPS and cellular modem powered down most of the time. But say once every 30 minutes, they would all power up, grab the GPS data, fire off an SMS message with the coordinates, then power back down again. It's not perfect, but it's a good compromise. |
