Land surveying is a technique in which professionals look at land and identify accurately the three dimensional positions of points and the distances between them. This is often used in order to calculate the data needed for maps, and in order to set boundaries of ownership. It can also be used for general mapping and there are many land surveying initiatives run by the government.
The basis of the world's current GPS system relied on a receiver being able to make contact with at least four satellites at any one time and by 1994 the US Department of Defence had established 24 satellites in orbit to achieve this aim. The Russian Military had its own "Global Navigation Satellite System", which became available to civilians in 2007, and there is also the European "Galileo Positioning System" and the Chinese "Compass Navigation System."
There are GPS tracking devices that exist for keeping tabs on kids, elderly relatives and vehicles. The use of a mobile phone is cheap, useful and unobtrusive and will allow you to know the whereabouts of the phone - thus giving you peace of mind about the position of its owner. This obviously needs the consent of the person carrying the phone, as legally you cannot just covertly bug your relatives, workmates and neighbours.
Increased security measures are another by-product of having a GPS tracker on your mobile phone. Downloading one of the many tracking programs can effectively LoJack your phone, making it simple to find and difficult for someone stealing it to put it to use.
The initial version of the embryonic system was called Navstar-GPS, which later became abbreviated to GPS and was made fully available to civil authorities after the 1983 shooting down of a Korean domestic aircraft which strayed into USSR airspace.
There is also no immediate notification that the mobile is LoJacked as it is controlled by the management application system, which will normally go unnoticed.
From its initial military concept, GPS tracking has now evolved into many civilian applications and along with satellite navigational systems there are implications for private surveillance and the GPS tracking of vehicles, people and pets. Geofencing ensures that a device remains within a predetermined area and geotagging allows attributes to be given to a specific GPS location such as a restaurant or hotel.
