First it was USA's GPS.
Then came Russia's Glonass.
China's Baidu.
Now new addition, India's Navic. With the launch of its 8th satellite it's now active. We only need a receiver that can use it.
Coverage isn't the whole world. Rather India plus surrounding region upto a distance of 70% of the width of India.
Accuracy 10m. Not too good for today's tech. But not too bad either.
