What is IRNSS (NavIC)? How India's Own GPS Works & Its Advantages

As we all know, India has successfully launched its own satellite navigation system known as IRNSS from Sriharikota. The full form of IRNSS is the Indian Regional Navigation Satellite System, and its operational name is NavIC (Navigation with Indian Constellation). The launch and development of IRNSS is a very proud achievement for all Indians. Thanks to the launch of our own satellite, we are no longer dependent on other countries for navigation purposes. India has now proudly joined the exclusive list of countries that have developed their own satellite navigation systems. Let's discuss IRNSS in detail, how it works, and the advantages of its development.

In today's highly technological world, we rely heavily on smartphones, cars, and other devices that use GPS (Global Positioning System) for navigation. The IRNSS (NavIC) system is India's very own alternative to the American GPS system. Before diving deeper, let's clarify the exact name:

Full-Form of IRNSS: Indian Regional Navigation Satellite System

What Is The IRNSS Satellite System?

IRNSS is India's completely self-developed satellite navigation system, equivalent to the GPS system developed by the USA. To understand how it works, think about how we use navigation apps on our smartphones or in our cars to track locations and find routes. Traditionally, these apps rely on the American GPS network. However, the USA isn't the only country with this technology. Other global navigation systems include:

GLONASS: Developed by Russia
BEIDOU: Developed by China
GALILEO: Developed by the European Union (EU)

For a long time, India did not have its own navigation network and relied entirely on foreign systems. Now, we are self-reliant. Indian scientists at ISRO have developed our own regional system, which we can proudly call India's own GPS.

The Proud Launch of IRNSS

We can proudly say that our country is now on par with nations like China and the USA in satellite navigation. The proud moment of the launch of the seventh IRNSS satellite took place on April 28, 2016. Before this, six other satellites had already been placed in orbit by Indian scientists. The IRNSS project has been actively progressing since July 2013.

You might wonder why India needed its own system when GPS already exists. The answer goes back to the 1999 Kargil War between India and Pakistan. During the conflict, India requested GPS data for the region from the USA, but the request was denied. Because of this, the Indian military faced significant strategic challenges. This event sparked the need for self-reliance, ensuring India would never again have to depend on another country's navigation system during critical times.

Cost And Development Time

The IRNSS navigation system was developed and successfully launched in less than three years. The total cost for the development of the IRNSS constellation was around 1,420 Crore INR. This is comparatively very low, primarily because all the technology and apparatus used for the development of IRNSS were indigenous to India. If a similar satellite network were developed in another country, the cost would likely have been substantially higher.

Services Provided By IRNSS

The navigation services offered by IRNSS are not limited just to India. Its coverage extends up to 1,500 km beyond India's borders, providing highly accurate location services to neighboring countries like Nepal, Bhutan, Bangladesh, and Sri Lanka. With all seven satellites focusing on this specific regional area, the location accuracy provided by IRNSS is incredibly precise.

From Testing Phase to Daily Use

During its testing phase, scientists actively monitored the navigation system to ensure all satellites were communicating correctly and fixed any operational errors. Now that the constellation is complete, the focus has shifted to the manufacturing of NavIC-compatible receivers. Today, many modern smartphones and vehicle tracking systems in India come with built-in NavIC support. Using IRNSS is highly cost-effective, especially for commercial use, compared to the heavy licensing fees sometimes associated with foreign systems.

Advantages Of The IRNSS System

There are several major advantages to using the IRNSS navigation system:

High Accuracy: The location tracking provided by IRNSS is highly accurate, specifically optimized for the Indian subcontinent, rivaling or even exceeding standard GPS accuracy in the region.
Regional Coverage: Services are provided not just in India, but also extended to India's neighboring countries.
Strategic Independence: We are completely independent of foreign navigation systems during wartime, natural disasters, earthquakes, floods, and other emergencies.
Cost-Effective: The IRNSS navigation system is significantly more cost-effective for domestic commercial integration compared to relying solely on GPS.
