Survive in the wilderness

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.

Privacy

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.

Q & A

Astrolabe doesn't automatically send SMSs if it has no GPS position, but it does so as soon as it acquires one (the delay is measured in seconds).

This is done is order to preserve the SIM card's credit, if for instance, you leave the GPS and the program running for an entire night while sleeping in a hotel.

What if there is no GPS signal?
The program waits until it acquires a new GPS position. Then, a new SMS is sent within (generally) 5 seconds.

If the time to automatically send an SMS is X, the SMS is sent only if more time than X has passed since the last sent SMS.

What if there is no phone signal?
If an SMS has to be automatically sent but can't be, the program keeps trying to send an SMS every 5 seconds, until it succeeds.
