News?<\/strong><\/h2>\n<ul>\n<li>The Indian armed forces are in the process of inducting a homegrown innovation along the country\u2019s northern and eastern borders which will help commanders identify friendly forces in a joint battlespace.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><strong>About Vayulink System<\/strong><\/h2>\n<ul>\n<li>Vayulink is a data link communication system developed by the Indian Air Force (IAF).<\/li>\n<li>The Vayulink system was showcased by the IAF at the <strong>Aero India 2023<\/strong> show in Bengaluru recently.<\/li>\n<li>It uses the Indian Regional Navigation Satellite System (<strong>IRNSS<\/strong>), also known as <strong>NAVIC<\/strong>, to send radio communication to the base station when the signals are low.<\/li>\n<li>The important aspect of the Vayulink system is that <i><strong>it prevents fratricide or friendly fire<\/strong><\/i>.\n<ul>\n<li>When installed in an aircraft, the system gives position of other aircrafts close by, encrypts traffic data over secured channel.<\/li>\n<li>When the planes are flying close to any friendly forces on grounds during a combat situation, the <i><strong>aircraft display gives the position of such forces on the ground including tanks and troops beneath<\/strong><\/i>.<\/li>\n<\/ul>\n<\/li>\n<li>The Vayulink system <i><strong>also prevents aircraft collision, provides better combat teaming and helps plan real-time basis <\/strong><\/i>where multiple teams can get together and go towards the target coming from different areas.<\/li>\n<li>The Vayulink system can also <i><strong>arm the pilot with real-time weather details before flying, thereby preventing accidents<\/strong><\/i>.<\/li>\n<li>It would help pilots with jammer-proof uninterrupted communication with the base station.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><strong>Need for Vayulink System<\/strong><\/h2>\n<ul>\n<li>After the <strong>Balakot air strikes in 2019<\/strong>, the IAF had shot down its Mi-17 V5 helicopter at Budgam by mistake, killing six personnel on board.<\/li>\n<li>The helicopter\u2019s IFF (Identification of Friend or Foe) system was also switched off, which had led to gaps in communication between the helicopter crew and the ground forces.<\/li>\n<li>Also, the IFF can only be applicable to an aircraft and requires radars to function.\n<ul>\n<li>On the other hand, Vayulink system can be carried by an aircraft, individual troops or armoured vehicles on ground.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><strong>Has the Vayulink System been Integrated into the Armed Forces?<\/strong><\/h2>\n<ul>\n<li>The Vayulink system can have a range of applications and is not confined to one service, but can integrate all combat entities through a single link.<\/li>\n<li>The IAF has already deployed the system on a trial basis at forward locations in the Western and Northern sectors.<\/li>\n<li>It has also been inducted into the Indian Army under the name <strong>Trishul link<\/strong>.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><strong>About NavIC<\/strong><\/h2>\n<p><strong>\u00a0<img decoding=\"async\"

(IRNSS).<\/li>\n<li>It is an independent stand-alone navigation satellite system which comprises of 7 satellites.<\/li>\n<li>It is developed by the <strong>Indian Space Research Organisation<\/strong> (ISRO).<\/li>\n<li>NavIC was approved in 2006 at a cost of <strong>USD 174 million<\/strong>.<\/li>\n<li>It was expected to be completed by late 2011, but only became operational in 2018.<\/li>\n<li>NavIC consists of <strong>eight satellites<\/strong> and covers the whole of India\u2019s landmass and up to <strong>1,500 km<\/strong> from its

Space Force.<\/li>\n<li>The main difference between GPS and NavIC is the serviceable area covered by these systems.\n<ul>\n<li>GPS caters to users across the globe and its satellites circle the earth twice a day, while NavIC is currently for use in India and adjacent areas.<\/li>\n<\/ul>\n<\/li>\n<li>Like GPS, there are four more navigation systems that have global coverage
