How does GPS(Global positioning system) work on phones?
On my n95, After Opening it, it would search for 5 satelites in the space,when three are found you can start navigating. You would see your 4 cardinal points widely,and a red arrow indicating the position u are like north east, as you walk it start rotating,it depends how you walk,if u go straight,it wont turn. So there is a place you can set where u can set d parameters to where u going e.g North 30¤ east 60.5¤ (well I didnt study Geography). It wud ask u wat u going by, car,canoe,horse foot etc .it calculate the approprate time to be there via wt ur transportation means is. The red arrow keeps u ontrack,calculating the meters u've passed and the one ahead. When you are there, 'Arrive' would cover the whole screen. Then it ask u wheather to search for it on The World map. Here u go, u gonna see your country,town and ur specific location on the map. Note: your keypad serves as the receiver so dont cover it.
