Our ancestors had to go to extreme measures just to maintain the loss. They erected monumental landmarks, laboriously draw up detailed maps and learned to read the stars in the night sky.

The precise positioning is possible using GPS receivers at reference point sites make corrections and positioning data from remote receptors. Tectonic studies surveying, geodetic control, and the plate are examples. release time and frequency, based on the precision clocks aboard the SVs
and controlled by the monitoring stations, is another use for GPS. Astronomical Observatories, telecommunications services and laboratory standards can be set precise time signals or controlled to accurate frequencies by special purpose GPS receivers.
