Explanation:
So, what are these remote sensing satellites? What do they
do? How are they useful to the society?
To understand this, let us begin with the word ‘remote
sensing’. When we say remote sensing, it means that it is
a method of collecting information about an object or a
phenomenon without having any physical contact with it.
Satellites carrying very sensitive cameras or radars and circling
the Earth in space hundreds of kilometres high are known as
remote sensing satellites. They transmit the pictures to ground stations through radio. Such pictures, taken in different colours
or in black and white, show a lot of details. Trained scientists
can manipulate and analyse those pictures in computers to
understand several facts, like estimating the net sown area,
underground water availability, mineral deposits through rock
colour, environment assessment, pollution levels, wasteland
development, and so on.
