If you don't know about NavIC, it is actually India's home grown satellite navigation system. Yes, it's like GPS. GPS is American made, and NavIC is made by Indian Space Research Organization (ISRO). NavIC is the short form of Navigation with Indian Constellation. It is also known as Indian Regional Navigation Satellite System (IRNSS).
As NavIC is available for civilian use over L5 band (and S band for military use), it is now offering regional coverage covering India and a region extending 1,500km around it. While American GPS, Russian GLONASS, European Union's Galileo, China's BeiDou have global coverage, i.e. all these 4 satnav services are Global Navigation Satellite System (GNSS). NavIC presently using only 7 satellites to cover a region centering India. As 4 out of 7 satellites are geosynchronous and remaining 3 are geostationary - as a result the satellites are always in line with Indian territories - that makes geolocation highly precise.
History of NavIC began in 1999, when US denied specific GPS data to India during Kargil war. The project of Indian GPS or IRNSS was approved in 2006, and planned to go operational by 2011. But it got delayed, eventually NavIC was launched in 2018.
