Hello, everyone, I welcome you all to an informative video
Whenever we travel or go to any unknown place
we generally track our location through
GPS
and what we do simply open google maps, search our destination and reach our destination
but have we ever thought how GPS work and how within seconds its track our location
in today’s video, I am going to talk about Gps what is GPS and how its works
but before proceeding please watch the full video without any skip, so let's begin
Gps full form is Global positioning system
Gps is a satellite navigation system which basically use to track our location
Gps is invented by Roger Lee Easton, Ivan Alexander Getting, Bradford Parkinson
Roger Lee Easton was the principal inventor or designer
gps Initially gps was used by us military and they mainly used to track enemies and attack on them
Later gps was publicly launched
and today gps technology is available in automobiles, smartphone and watches
For worldwide gps coverage there are total 24 satellites
and in 1995 they worked and improved the gps services
and after 2000 quality and accuracy of gps was improved
These gps satellites are deployed in the space
which is 19300 kilometer away from earth surface
Now we will talk about some gps components
what are the components which help GPS to determine the location
space satellite
which is basically used to determine our location and provide geographical location and time to receiver
Ground control
this is used to control the satellite by tracking and monitoring transmission of signals
user equipment
gps receiver, transmitter which is present in our automobiles smartphone and watch
Now lets talk about how gps works
gps make use of the technology called trilateration
Which is use to collect signals and calculate location and velocity
Let me make it easy for you
In our phone there is a gps unit which is use to receive signals
from satellite and these signals are used to calculate accurate location
and with the help of atomic clock present in satellite provide accurate time
and this time can be accurate till billion of years
if GPS receives signals from more than 3 satellites then the location of the person is determined
Now lets talk about 5 main use of gps
location
which is used to determine the target location of the user
navigation
use to calculate distance between point a to point b
tracking
which is generally used by police or government organization to track the person
mapping
which is used to design the google maps
timing
where with the help of atomic clock accurate time is measured
Hope u have understood what is gps, who invented gps and how gps work
before ending please share and comment below
on which topic i should make the next video
so lets see you all in next video till that stay safe stay learning
