compliance will largely happen automatically through service providers.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">However, accurate, traceable time can matter significantly when investigators or courts need to reconstruct events, such as in fraud investigations.<\/span><\/li>\n<\/ul>\n<h2><b>Why Not Just Keep Using GPS?<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Most people currently obtain time indirectly through GPS, which is owned and controlled by the United States \u2014 and can be degraded or denied at will.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">During the <\/span><b>Kargil War<\/b><span style=\"font-weight: 400;\">, India was denied access to GPS information it had sought, which became the genesis of India developing its own navigation system.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This led ISRO to build the <\/span><a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/irnss-navic\/\" target=\"_blank\"><b>Indian Regional Navigation Satellite System (IRNSS)<\/b><\/a><span style=\"font-weight: 400;\">, now known as <\/span><b>NavIC<\/b><span style=\"font-weight: 400;\">, providing independent regional satellite-navigation coverage.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Since time is critical to navigation, NavIC satellites carry atomic clocks, and its ground stations are traceable to IST \u2014 giving India an alternative, sovereign source of accurate time.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">NPL has also developed indigenous primary frequency standards and is working on advanced atomic clocks, upgrading its timing infrastructure.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This is to ensure India has an independent, resilient time source \u2014 one that can keep critical services running even if international traceability links fail.<\/span><\/li>\n<\/ul>\n<h2><b>Conclusion<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The IST Rules, 2026 transform India&#8217;s time reference from a scientific convention into a legally enforceable standard, ensuring uniform synchronisation across sectors for better accountability, cybersecurity and infrastructure resilience.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Combined with indigenous capabilities like NavIC and NPL&#8217;s atomic clocks, this move strengthens India&#8217;s technological self-reliance and reduces vulnerability to disruptions in foreign systems like
