Gps - GPS is the short form for Global Positioning System and it is used to locate one's position on the earth. It communicates with satellites to calculate your position in terms of latitude, longitude and altitude. Combine this data with a map and you know where you are standing.

Most mid range phones these days come with inbuilt gps recievers and usually have mapping software preloaded on them. On a nokia phone you would get ovi maps, on an android phone you get google maps and so on..
