To plot a certain East/West point on the Globe.
equator and hemisphere
That is the center of the coordinate system, which uses latitude and longitude.
it uses latitude and longitude
The same one the world uses. Latitude and longitude!
I think China is one of them but China uses to have five time zones. (see the related question)
Cebu City is located in the Philippines. The latitude and longitude is 10-18'-40" N and 123-53'-30" E and uses the Asia/Manila time zone.
Global Positioning System (GPS) uses timing signals from four satellites to determine your latitude,longitude, altitude and precise time.
Together, latitude and longitude numbers can identify an exact position on Earth, giving its distance from the equator (latitude) and its relationship with the meridians that measure east and west (longitude). They were developed to provide uniform navigational information and can be determined using the calendar date and the known positions of stars. Latitude and longitude provide a "grid system" by which any location on Earth can be specified.
the system uses a series of 24 satellites called navstars. they send the exact latitude,longitude,altitude,and time to a hand-held receiver.
you find a location with latitude and longitude. longitude is east and West.
