My teenage step-daughter is autistic, and tends to want to run away from school, leisure-club and sometimes even from home. This is very bad for her safety, and a great concern for us.

I am looking for a way to track her, so we can find her again when she runs away.

Here is my ideal (possibly unrealistic) scenario:

• Tiny GPS device with GSM/GPRS
• Can be woken up via sms when needed (so battery will last longer)
• When activated, spins up GPS + Data connection and starts hitting a predefined URL with device ID and long+lat every 15 seconds
• Battery life 7 days on standby (ie. when never activated)
• Can be disabled put back to sleep via sms

I have googled and researched this for a while, but have yet to find a device that fits these requirements.

The solution could also be a mobile phone of some sort, that I can lock down.

You could do most of that with any Android handset using prey
