It's the system the Indian Space Research Organisation says will finally provide GPS connectivity to the most rural parts of India and come 2016, it could be fully operational and accurately guiding you to within 20 metres of your destination.

The Indian Regional Navigation Satellite System (IRNSS) will given India its own Global Positioning System, something for which it is still dependent on the US-owned GPS system.

How does it work?
To completely cover the the country, Isro will be using seven satellites of which four are already in orbit.

So satellites IRNSS-1A, 1B, 1C, and 1D are already in orbit and the three remaining satellite IRNSS 1E, 1F and 1G - will be launched in January, February and March respectively.

Isro is hoping to have the IRNSS system operational by July next year and has been working to convince mobile device manufacturers, Global Information System Technology developers and navigation device manufacturers to switch to the new system once it's up and running.

Isro is asking device manufacturers to include additional hardware in devices to receive the signals from the IRNSS satellites, which one official had told the Times of India, would "reduce the errors caused by atmospheric disturbances significantly."


How can you use IRNSS?
The IRNSS is expected to provide location accuracy to almost 20 metres. US-owned GPS has accuracy is also estimated to be around the same in India.

Data from the IRNSS can be used in services like car navigation, aircraft and shipping routes, smartphones and other devices, the scientific advisor to the Defence Minister has been quoted as saying in a report.

This will mean transport can be planned more efficiently since real time, accurate data will be available for anything in India and upto 1500 km from its borders.

But the biggest advantage is for Indian defence forces since they would finally have their own satellite data with which they can carry out operations.

G Satheesh Reddy, the scientific advisor to the Defence Minister, had said that so far the data received from the satellites had also been very useful for defence purposes.

While US and Russia have their own satellite navigational systems that are important for defence purposes as well, defence experts had noted that the satellite network that will cover India and 1500 km from its boundary will play an important role in India's defence of its boundaries.

There is a Good News and a Bad News.

First the Good News, The area covered by the IRNS is phenomenal.

Assumption,

ACTUAL,

This actually means it not only covers India, but also covers the Entire Indian Ocean, Significant parts of Africa, Australia and entire China. :D


Now this signal is to be combined with the GAGAN to bring up the accuracy to 1.5 meters :enjoy:

Now for the BAD News.

We have NO RECEIVERS YET :lol:

So this thing is pretty much a white elephant for now. By the time we design a receive and make it production quality and sell it the life of the satellite would have expired :cheesy:
 
. .
Revolutionary Step by ISRO.

It would have been revolutionary if there was a parallel development of an IRNSS signal receiver and processor which can be used commercially or even by the military :cheesy:


But as usual ISRO has said that its not their job to provide for receiver. Anyone who wants to use the IRNSS is free to develop the receive and use it :lol:
 
.
Good Job ISRO, keep going.

Receivers are no big deal. Various standards have already been proposed:

LOL.... are you kidding me ?

What is a big deal is a Rs. 1,420 Crores floating in space with No practical use in sight.

I did not say its impossible to make it IRNSS Receivers.

I said that till date NO ONE has made IRNSS receivers. Which means it will never be used till someone first builds it and mass produce it and sell it.

Why would any commercial entity do that when its far more cheaper to buy a GPS device ? :lol:

Even DRDO has not build a receivers which can be used by missiles. Indian Navy has not built receivers which can be used by the Naval ships and Submarines. Nada for IA or IAF.


So for the moment, this is what it looks like.

This is not good Portfolio Planning. A good project planning ? YES.

But a VERY POOR Portfolio Management.
 
. . .
Reason behind this. But DRDO hasn't worked on the recvs as of yet?

Why would DRDO make the receive ? Nobody has told them to.

Since ISRO made the transmitter, making the Receive was their responsibility too. But they do not want to be bothered with such small silly practical matters. They want to look at the Big picture :lol:
