Context<\/strong>: Recently, an IndiGo ATR aircraft landed at Kishangarh Airport in Rajasthan using GAGAN, India\u2019s own Space-Based Augmented System (SBAS).<\/p>\n

Why this is a significant achievement for India?<\/h5>\n

Though only a trial, the landing was a significant achievement that could allow aircraft to operate in poor weather conditions at smaller airports<\/strong> that lack expensive instrumentation.<\/p>\n

The landing was also a rare demonstration of how the US Global Positioning System (GPS) could be augmented for use in critical \u2018safety of life\u2019 applications<\/strong> like aviation.<\/p>\n

More significantly, GAGAN shows the profound effects that satellite navigation has had on both commercial and military undertakings<\/strong>. As satellite navigation matures, these effects are only likely to deepen and thus influence India\u2019s own relative power in the world.<\/p>\n

What is GAGAN?<\/strong><\/h5>\n

GAGAN is an acronym for GPS Aided GEO Augmented Navigation<\/strong>, and its infrastructure reaches from earth to space.<\/p>\n

On earth, reference stations receive American GPS signals that are then collated and corrected for ionospheric distortions and other errors.<\/p>\n

The corrected signal is then broadcast from three Indian geostationary satellites, providing a more accurate and reliable service for aircraft.<\/p>\n

What are the augmented systems already in place around the world?<\/h5>\n

Utility of augmented systems<\/strong><\/span><\/p>\n

–<\/strong> Besides guiding aircraft, these augmented systems could help ships navigate narrow waterways, assist the coordination of train routes, and manage traffic jams on highways.<\/p>\n

Augmented systems around the world<\/strong><\/span><\/p>\n

GAGAN<\/strong> is only one of many augmented systems already in place or being developed around the world.<\/p>\n

The WAAS system<\/strong> covers North America, while EGNOS covers Europe<\/strong>.<\/p>\n

China is developing its own system based on the BeiDou constellation of navigation satellites<\/strong>. As China\u2019s reliance on BeiDou indicates, spacefaring states are setting up their own constellations. BeiDou is the most ambitious of these, with a constellation of 45 satellites providing global coverage. Europe\u2019s Galileo has 24 satellites and Russia\u2019s GLONASS, 23.<\/p>\n

The Indian Regional Navigation Satellite System (IRNSS)<\/strong>, also known as NavIC, consists of just seven satellites and provides services in India and its neighbourhood. Together, these satellite services complement GPS<\/strong>, providing better coverage in some regions. However, they also compete with GPS<\/strong>, providing users with viable alternatives and eroding what was effectively an American monopoly.<\/p>\n

Why India has struggled with NavIC?<\/h5>\n

India has struggled to get civilian users on NavIC<\/strong>. A major reason for this was the lack of chipsets that could receive NavIC signals on mobile phones or vehicles.<\/p>\n

–<\/strong> This prompted ISRO to reach out to chipmakers like Broadcom and Qualcomm<\/strong>. Mobile phone manufacturers have also begun to provide NavIC support.<\/p>\n

–<\/strong> The government has even made it mandatory for public and commercial vehicles in India to carry NavIC-based trackers.<\/strong><\/p>\n

Why indigenous navigation systems are a necessity?<\/h5>\n

National security<\/strong>: In times of crisis, other states could choose to deny such services, wreaking havoc on both businesses and military operations. Indeed, satellite navigation cannot be separated from its military utility.<\/p>\n

–<\/strong> In 1999, the US denied India the use of GPS to help fight Pakistani intruders in Kargil, a decision that sparked India\u2019s efforts to build its own navigation system.<\/p>\n

Way forward<\/strong><\/p>\n

In the coming decades, competition over satellite navigation is likely to intensify as states improve their own capabilities and try to deny them to adversaries.<\/p>\n
