Find all the GPS systems
information you need
Are you looking for some GPS systems information? Then
come to see us. We have been providing technical courses and
advanced GPS training on GPS systems information since
a long time ago. We offer more than 20 courses on professional
GPS and all you want to know about GPS systems information.
But, first than anything, what is exactly a Global Positioning
System (GPS) ?
It is a satellite-based navigation system made up of a network
of 24 satellites placed into orbit by the U.S. Department of
Defense. At first, GPS was going to be used by military
applications, but later in the 1980s, the government allowed it
to be available for civilian use. It doesn't matter the weather
conditions, GPS keeps working anywhere in the world and the
whole day. It is not necessary any subscription fees or setup
charges to use GPS.
The second question would be: How it works?
GPS satellites circle the earth twice a day in a very precise
orbit and transmit signal information to earth. GPS receivers
can calculate exactly where the user is by taking this
information and using triangulation. In other words, the GPS
receiver compares the time a signal was transmitted by a
satellite with the time it was received. The time difference
tells the GPS receiver how far away the satellite is. And by
repeating this procedure with a few more satellites, the
receiver can determine the user's position and show it on the
unit's electronic map.
A GPS receiver can calculate the latitude and longitude and
track movement if it is locked on to the signal of at least
three satellites. And it can determine the user's latitude,
longitude and altitude using four or more satellites. But it
doesn't end with this, because once we have the user's position,
the GPS unit can calculate other information, such as speed,
bearing, track, trip distance, distance to destination, and much
more. So not just you can know where exactly somebody is, but
also you can know a lot of things about that person, and it
doesn't matter where in the world that person may be.
There is so much more GPS systems information and a
lot of things you can learn to understand and use a GPS system
correctly and you can find all of them just by looking for us.
