India's Satellite "NAVIC"ation system

Satellite navigation is not new. We use it all the time in our smart phones and cars. We are all well versed with GPS(Global Positioning Satellite) which is the most widely used SATNAV(Satellite Navigation) right now. SATNAV uses a group of satellites, at least 4, to calculate the position of an electronic receiver placed in an object, be it a phone or a vehicle, by using the radio signals transmitted from the satellite.
On April 28th , Thursday afternoon India has successfully launched its 7th navigation satellite, IRNSS-1G (Indian Regional Navigation Satellite System) successfully to its orbit. And of course, it is obviously been launched by ISRO's world renowned, trust worthy PSLV(Polar Satellite Launch vehicle) . It was PSLVs 34th flight. It will be put in its orbit in the coming days.
The name given to the mission's PSLV and SATNAV series were like this

PSLV-C31, PSLV-C32, PSLV-C33

India's IRNSS-1G was the last in the seven satellite constellation. After this successful mission India is ready to take on others who were already in this game. India's IRNSS give two type of services one for ordinary, open source , for civilians and other is restricted version where authorised users can have access. Prime Minister Mr. Narendra Modi named IRNSS system as NAVIC (Navigation With Indian Constellation) saying it is a gift to people by scientists. Right now it is not been officially declared operational.

India is now a proud owner of an independent SATNAV system, which is completely homegrown. There is always a political and defensive edge in such technologies. With this we now stand tall with others like USA (GPS), Europe (Galileo, which will only be completely operational on 2020 with a group of approx. 40 satellites, making it the biggest player), China (BeiDou), and Russia(GLONAS). India is currently providing only regional services in and around it's borders, where GPS and GLONASS provide global positioning services. 

First Chandryaan which gave India's space dream a real push then secondly MOM(Mars Orbiter Mission) and now this, IRNSS. way to go INDIA.
