In the Kargil war, India wanted to know the location of Pakistani Army. It asked America to help out but he refused to tell the location of army. Many of you might be thinking why am I telling all this? The reason is that at that time America had its global positioning system through this, he could have helped India with the location because at that time, we were not equipped with such facilities. Though India won the war but at that time ISRO decided we never have to face the same situation again and ISRO did it.
NavIC – What is it?
So, here we are with our own indigenously developed global positioning system known as “NavIC” (Navigation with Indian Constellation). It is also known as Indian Regional National Navigation System. It is developed by Indian Space Research Organization. The objective of NavIC is to create and implement an autonomous and self-made space based on navigation system which can be used in national interests. The project was approved in 2006 by the Government of India with the completion deadline of 2016.
Its features and utility
NavIC will provide its services in two forms. For normal people like us and all other users it will provide Standard Positioning System (SPS) and for some authorised users like military, navy, police and government it will provide Restricted Service (RS). Restricted services are encrypted services which can only be given to a body in case of the nation’s security or other valid reasons.
It will provide pithy information about the location and weather for users in India and within the 1500 km periphery, which can be called its Primary Service Area. It also has an Extended Service Area which extends from 30 degrees south latitude to 50 degrees north latitude and from 30 degrees East to 130 Degrees east.
Use cases of NavIC
This homegrown service can be used for the following purposes:
- Navigational purposes whether on land, water or air
- Connecting and integrating with mobile phones to guide about the location and to replace the GPS.
- Visual and voice navigation for drivers
- Vehicle tracking and fleet management
- Disaster management
- Accurate and precise timing
- Navigation tool for travellers
First navigation feather in our cap
After US, Japan, Russia and China, India is also in race. Two decades before India requested to America to help with their GPS, at the time of Kargil war. America refused to help India. Now India gave the answer to America in the form of NavIC. In 2018 India added first navigation feather in their cap.
Is it more accurate than GPS?
Yes, it is much more accurate than American counterpart. No doubt GPS has more satellites than IRNSS but it is more accurate. The reason is the navigation major has 24 working satellites for the whole of the earth but in the case of our indigenous one, 7 satellites are only for India. The numbers of satellites which are available to ground receiver of GPS are limited while in latter one they will cover each nook and corner with complete accuracy. GPS only uses L-Band signals while NavIC uses S and L band signals. By using both the bands the accuracy of NavIC will increase by 5 meters. This is far better than 20 meters accuracy provided by Global Positioning System along with the help of GPRS. India’s indigenous invention will not only give accurate results for urban areas but it also covers the rural verticals with the same accuracy.
India is still planning to do something extra to enhance the power of NavIC. NavIC system is planning to increase their constellation size from 7 to 11. This is all about Indian Navigation System NavIC. Now we all have to wait and watch for the upcoming achievements. Get in touch with us for more updates. Till then keep reading.
