The Indian Regional Navigational Satellite System (IRNSS) is a critical component of India’s strategic and technological advancements in the field of navigation. Established to enhance the nation’s self-reliance in navigation and reduce dependence on foreign systems, IRNSS plays a pivotal role in addressing the unique geographical and security challenges faced by India. This indigenous satellite navigation system consists of a constellation of satellites strategically positioned to cover the vast expanse of the Indian subcontinent and surrounding regions. IRNSS aids navigation through precise positioning and timing information, benefiting a wide array of applications, including transportation, agriculture, disaster management, and defense. By providing accurate and real-time data, IRNSS ensures improved navigation capabilities, allowing for more efficient and secure operations across various sectors. The system’s significance lies not only in bolstering India’s technological prowess but also in fostering economic development and safeguarding national interests by offering a reliable and autonomous navigation infrastructure.

- Conclude by highlighting the prospect that IRNSS would contribute both, politically and economically.
Answer:
The Indian Regional Navigational Satellite System (IRNSS) is a critical space-based navigation infrastructure developed by the Indian Space Research Organisation (ISRO). Launched in April 2018, IRNSS aims to provide accurate and reliable positioning information over India and the surrounding region. It is a set of 8 satellites whose primary purpose is to offer an independent regional navigation system to reduce the country’s dependence on foreign systems such as GPS (Global Positioning System).
Indian Regional Navigational Satellite System (IRNSS) is needed:
- Strategic Independence: Relying on its own regional satellite navigation system, India reduces dependency on foreign systems like GPS, GLONASS, and Galileo, ensuring strategic independence and security.
- Disaster Management and Emergency Response: IRNSS provides accurate real-time positioning data, crucial for disaster management and emergency response. During natural disasters like floods or earthquakes, NavIC enables authorities to locate affected areas, deploy rescue teams, and coordinate relief efforts effectively.
- Improved Navigation Accuracy: NavIC offers better accuracy than the standard GPS in the Indian region. In aviation, the precise positioning from NavIC aids pilots inaccurate approach and landing, enhancing safety during flights.
- Agriculture and Farming: The system’s precise timing and positioning services benefit agriculture. Farmers can use NavIC for precision farming, optimizing irrigation, and monitoring crop health, leading to increased agricultural productivity.
- Transportation and Navigation: IRNSS enhances transportation by providing accurate navigation data. Commercial shipping and maritime industries utilize NavIC for precise vessel tracking, route planning, and safe navigation in Indian waters.
In Navigation, IRNSS will help in the following ways:
- Accurate Positioning: NavIC offers a position accuracy of better than 20 meters in the primary service area, which includes India and its surrounding region. In the extended service area, the accuracy is better than 100 meters.
Example: For travelers, hikers, and drivers, knowing their exact location with high accuracy helps them reach their destinations efficiently and safely.
- Real-time Navigation: IRNSS provides real-time positioning and navigation services, enabling users to receive up-to-date location information and plan their routes accordingly.
Example: Navigation apps on smartphones can use NavIC’s real-time data to provide turn-by-turn directions and reroute drivers in case of traffic congestion.
- Navigation in Challenging Environments: NavIC’s dual-frequency capability (L5 and S-band) helps mitigate signal degradation and improves navigation accuracy in challenging environments like urban canyons and dense forests.
Example: Emergency responders can rely on NavIC signals in densely populated urban areas or dense forests to accurately navigate and reach incident locations faster.
- Terrestrial Navigation: NavIC facilitates terrestrial navigation, aiding hikers, travelers, and outdoor enthusiasts in determining their exact location and finding the right path.
- Aerial Navigation: NavIC’s accurate positioning is beneficial for aerial navigation, including aviation and unmanned aerial vehicle (UAV) operations, ensuring safe and reliable flight paths.
Example: Pilots and UAV operators use NavIC to ensure precise flight paths and landing approaches, enhancing safety in the skies.
- Precise Timing: NavIC offers precise timing services, which are essential for various applications like financial transactions, telecommunications, and network synchronization.
Example: Telecommunication networks, financial institutions, and data centers rely on NavIC’s precise timing signals for synchronization, ensuring smooth and efficient operations.
WAY FORWARD:
- Compatibility: NavIC is not in wide use in India primarily because mobile phones have not been made compatible to process its L5 and S-band signals. The introduction of the L1 band could help overcome this issue.
- Government incentives: The government has been aggressively promoting NavIC but smartphone manufacturers want time – at least till 2025. Hence, the government must incentivize the manufacturers for faster adoption.
- Extend range: Currently, beyond the 1500 km range, equipment using NavIC has to use other systems. To make the system global at some point, India should develop plans to add Middle Earth Orbit satellites to the system.
After the US, Russia and China had their navigation systems, India became the fourth country to have its independent regional navigation system. Unlike GPS, however, IRNSS is a regional and not a global navigation system. But now with the recognition as a component of the World-Wide Radio Navigation System (WWRNS), the Indian navigation system is similarly placed as GPS, most commonly used by marine shipping vessels across the world or the Russian Global Navigation Satellite System (GLONASS).
