A mobile phone or tablet calculates it's location by receiving radio signals from GPS satellites in space. The LocationOf GPS Tracker application
can be used to periodically record locations of the device and send them onto the live GPS map. You can then view these recorded locations from your desktop computer, laptop, tablet or mobile device at your personal LocationOf.com profile page. Please note that in order for GPS tracking to work the LocationOf app and the device must be actively on and be connected to a network.
