Imagine you are playing a game of hide and seek, but in this game, you have to find your friend in a really big place like a giant playground or a huge park. But you can't find them because you don't know where they are. So, what can you do to find them?
Well, you can use something called a GPS. A GPS is a fancy device that can tell you where you are and where you want to go. It does this by using signals from something called satellites that are high up in the sky.
Now, imagine a much bigger version of this GPS for a whole country like India. That's what the Indian Regional Navigation Satellite System (IRNSS) is! It's a system of satellites that India has put into orbit around the Earth to help people figure out where they are and where they want to go.
Just like a GPS, the IRNSS uses signals from these satellites to help people navigate or find their way. It's particularly useful in places where GPS signals might not be very strong or reliable, like in mountains or forests.
The IRNSS has seven satellites that work together to make sure people in India can use this navigation system wherever they are. This system is important because it helps people find their way, whether they are driving a car, flying a plane, or even out at sea.
Think of it like having a big, powerful compass that can help you find your way around a very large playground. And because it's from India, it's like having a special secret map that only people in India can use!
