Gps2sms

From Wikipedia, the free encyclopedia

The term GPS2SMS is used to indicate the transfer of Gps-coordinates by means of SMS (text messages).

For this the following applications exists:

burglar system for vehicles and vessels (alarm goes off if it is transported illegally)
tracking & tracing (following an object, e.g. a sea container).
geofencing (alarm goes off if someone enters a prohibited area).
digital bread crumb track of a route followed.
a message for a tow truck or emergency services (911 / 112) about the localization of broken down vehicle or a driver with problems.

SMS messages can be sent by several devices, as long as they have a GSM modem and a GPS receiver. Handheld devices exist, as well as built-in systems for vehicles and programmes for desktop PC, laptop, PDA and Smart phone. Some hobbyists build their own solutions, such as a small device that links a GSM phone to a GPS receiver (using a bluetooth, Wi-Fi or USB port).

For theft detection of a vehicle a device can be used that sends an alarm text message containing the coordinates of the object to be monitored, as soon as it leaves a certain protected area.
