SMS your GPS position
Use your PDA to acquire your GPS position and send it through an SMS.
The GPS position is update every 5 seconds (in order to conserve energy).
SMSs can be sent automatically at regular time intervals.
Do you like hiking?
What if you go out in the wilderness and have an accident? How do you direct a rescue team to your location?
You can use Astrolabe on your PDA to acquire your GPS position and send it through an SMS to your friends / parents / children / rescue team.
SMSs are not encrypted, so anyone who tracks your phone number can tell your precise position by reading the SMSs with your GPS position.
However, it's debatable whether this is relevant because if someone tracks your phone number, they may already know the position of your phone in the communication grid.
