✅ Why in News : Usage of Indian Regional Navigation Satellite System(NavIC system) has increased in sectors like transportation and personal mobility. ๐ธThere is also an increase in the number of NavIC enabled smart mobile phone models in the Indian market. ▪️About Indian Regional Navigation Satellite System ( IRNSS ) ✅IRNSS is an independent regional navigation satellite system developed by the Indian Space Research Organization (ISRO). ✅The main objective is to provide reliable position, navigation and timing services over India and its neighbourhood. ✅IRNSS is a regional and not a global navigation system. ✅Unlike the widely used GPS which includes 24 satellites, NavIC has 8 satellites and their range is within India and its adjoining regions extending up to 1,500 km from the country’s border. ✅Technically satellite systems with more satellites provide more accurate positioning information. However, compared to GPS which has a position accuracy of 20-30 metres, the...
๐Carbon Dating Method ✅ The District Court in Varanasi allowed a petition seeking Carbon Dating of the structure inside the Gyanvapi mosque that the Hindu side has claimed is a ‘ Shivling ’. ▪️What is Carbon dating? ✅It is a widely-used method applied to establish the age of organic material, things that were once living. ✅Living things have carbon in them in various forms. ✅The dating method makes use of the fact that a particular isotope of carbon called C-14, with an atomic mass of 14, is radioactive, and decays at a rate that is well known. ✅The most abundant isotope of carbon in the atmosphere is carbon-12 or a carbon atom whose atomic mass is 12. ✅A very small amount of carbon-14 is also present. ✅Process : Plants get their carbon through the process of photosynthesis, while animals get it mainly through food. Because plants and animals get their carbon from the atmosphere, they too acquire carbon-12 and carbon-14 isotopes in roughly the same proportion a...
