What do the GPS functions exactly mean?

Firstly the GPS system is able to interpret the GPS data coded into the signals received with the help of the eg. VdS protocol and display it on the map (for example to display the map data of personal or vehicle trackers), and as an additional function, it looks up the position of the given objects based on the address of the object and displays it on the map.

Secondly, connected with the UniAlarm GPS Watch personal tracker and alarm device it is able to locate the position or a track of a person and display it on a map, and also to virtually protect or enclose a given area.
