GPS, Global Positioning System ; It is an
abbreviation consisting
of the initials of the words meaning
global positioning system in
Turkish. What is GPS? Let's take a
closer look at the question;
They are devices that can find their
position on Earth thanks
to highly accurate clock signals
from at least 3 (at least 4 if
altitude information is included)
GPS satellites. GPS is a global positioning
service developed by the United States. In addition to GPS, there are also
global positioning systems such as GLONASS
developed by Russia, IRNSS developed
by India, BeiDou (BDS)
developed by China and Galileo
developed by European countries.
Global navigation satellite system (GNSS) to
all these systems is given the name, but
because it is the first
system to come out, most of these systems
are often referred to as GPS.
GPS Satellites
As of today, USA's GPS and Russia's
GLONASS systems can be used actively.
BeiDou and Galileo systems continue
to be developed to be operationa
l globally in 2020.
Working principle of GPSIt is as
Working principle of GPSIt is as
follows: GPS satellites in Earth orbit
contain highly accurate atomic clocks.
These clocks work in sync with
other satellites and clocks on earth,
and any deviations are corrected daily.
Satellites continuously send their
position in orbit and this sensitive time
information to the Earth. When any
GPS receiver in the world is operated,
it needs these signals from at least
3 of the GPS satellites in the coverage
area, and the GPS receiver, which
can learn the distance from each satellite
by finding how much the incoming
clock information deviates from the
absolute time, can calculate its position
on the earth with this information.
Navigationour devices and
Navigationour devices and
mobile phones can show our
current location on
the map by using this location
information and calculate the necessary route
information to reach the destination
we have chosen, by calculating the
shortest route, the most economical
way, etc. can choose. For this process,
map information must be installed in the
device. On mobile phones,
on the other hand, map information can
be pre-loaded and the
most up-to-date map information can
be obtained through an internet
connection, as well as opportunities
such as instant traffic information.
