What is GPS?
▪ GPS stands for Global Positioning System. It is a satellite-based
system consisting of a minimum of 24 satellites that provides
users with positioning, navigation, and timing services. It’s also
used to describe the positioning system itself, for instance,
your transport’s built-in GPS.
The creators of GPS
▪ There are lots of scientists who developed and improved the GPS system.
The most famous ones are Brad Parkinson, Ivan Getting, Roger L. Easton.
Parkinson is famous as “the father of GPS” because of his great contribution
to the study of GPS and navigation systems.
How GPS works
▪ GPS is a search system that consists of three
main parts:
▪ a) Satellites – They serve like stars in the
constellation. They guide ground stations and
help to find the exact location of an object.
▪ b) Earth stations – They are used for
monitoring and controlling satellites. Ground
stations are responsible to identify an object’s
location.
▪ c) Receivers – They are constantly getting
signals from the satellites. Highly advanced
receivers can even identify the precise location
within a fraction of an inch, which is a very
impressive precision.
Environmental effect of GPS
▪ What is the environmental effect of GPS?
▪ Precise tracking of environmental disasters such as fires
and oil spills can be conducted more efficiently. Accurate
positional information from GPS system helps researchers
in crustal and seismic monitoring. Monitoring and
preservation of endangered species can also be facilitated
through GPS tracking and mapping.
Environmental impact of GPS
▪ The use of GPS has helped to improve ecological situation
in our planet. For example, it has produced such
substantial environmental benefits, as decreased carbon
emissions (CO2), increased water efficiency, lowered use
of environmentally sensitive inputs, and reduced waste,
lowered pollution level.
