Latitude
You need at least 3 satellites. More is always better.
Port Jackson, or better known as Sydney Harbour.
They are used for finding one's location on the Earth's surface. Also, longitude is used for telling time in other parts of the world, based on one's own location and time. Generally, every span of 15° in longitude is equal to an hour's difference in local time (solar day time).
The point at which the equator (0° latitude) and the Prime Meridian (0° longitude) intersect has no real significance but it is in the Atlantic Ocean, about 380 miles (611 kilometers) south of Ghana and 670 miles (1078 km) west of Gabon.Source: About.com
you get a decent GPS and put in the longitude and latitude of the place you want to go to. then you go in the direction that the GPS tells you until you are right on top of the coordinates you put in.
None would ask about length and width of one country, Better to ask for Longitude and Latitude

The system of latitude and longitude was invented to do that, so that everypoint on Earth could have its own unique set of numbers, and could never beconfused with any other point. Something like the address of your housebut better.
-- Gulf of Guinea, south of Accra, Ghana -- Since everywhere on the equator is zero latitude, and everywhere on the Prime Meridian is zero longitude, the point that is common to both had better have the coordinates zero/zero .
Latitude/longitude . . . . . 3 satellites Elevation . . . . . 4 satellites But the more birds, the better the accuracy of the position data. Also, if you paid less than $1,000 for your instrument, then don't believe anything it tells you for elevation.

it's over there
Since that point is in the Atlantic Ocean about 500 miles from the coast of Africa, you'd better be in a boat.
Latitude and longitude are numbers that you can measure as close as you want to the truth, but never exact. Every point on Earth has a different set of coordinates. In principle, two pencil dots on the same piece of paper have different coordinates. And to ask for a set of coordinates that represents the location of an entire nation is especially meaningless. -- Panama occupies the range of 7.2028° - 9.6365° North latitude, and 77.1586° - 83.0461° West longitude. -- The Southwest end of Runway-04 at Aeropuerto Internacional Enrique Malek just south of David is located at 8.3861° north latitude 82.4397° west longitude. -- The north end of Runway-21R at Tocumen International Airport is located at 9.0933° north latitude 79.3750° west longitude. -- The center of the pitcher's mound at Roberto Mariano Bula Stadium in Colon is located at 9.3566° north latitude 79.8959° west longitude. -- The south end of the runway at Bahia Piñas airport, at Puerto Piña on the south coast of Panama about 30 miles northwest of the border with Colombia, is located at 7.5849° north latitude 78.1809° west longitude. Other points in the country all have different coordinates. The figures above are precise to within about 12 meters, and accurate to within perhaps 25 meters. If you need it better than that, you'll need to hire your own land survey.
