GPS Navigation – How the System Functions?
Global Positioning System, GPS in short, is a satellite assisted navigation system providing
location and time information anywhere on the Earth.
GPS navigation is possible only
when the GPS system installed in the vehicle has unobstructed line of sight to a
minimum of four GPS satellites in the space.
The facility is maintained by US
government and is free of cost.
The position of the vehicle fitted with GPS is accurately calculated by the signals sent by the
GPS satellites.
Each of these satellites independently transmits signals continuously
about the time the message was sent and the position of the satellite at the time the
message was transmitted.
In turn, with the help of Trilateration or any other suitable
algorithm, the receiver determines the exact location of the vehicle by considering the
time elapsed in transit coupled with the satellites location.
The location is displayed on a
digital display device.
