India marched towards establishing its own navigation system on Friday when its Polar Satellite Launch Vehicle (PSLV-C24) put into precise orbit the country’s second navigation satellite, Indian Regional Navigation Satellite System (IRNSS-1B). The 1,432-kg IRNSS-1B will form part of a constellation of seven navigation satellites.

It was the 25th success in a row for the PSLV, after it majestically lifted off from the first launch pad at Sriharikota at 5.14 p.m. After 19 minutes of flight, IRNSS-1B was put into a perfect orbit.

K. Radhakrishnan, Chairman, Indian Space Research Organisation (ISRO), said two more IRNSS satellites would be put into orbit before 2014-end and three more before mid-2015.

Mission Director P. Kunhikrishnan, said the mission accuracy was such that the satellite achieved a perigee of 283 km against the target of 284 km and an apogee of 20,630 km against the targeted 20,650 km.

“The satellite is doing extremely well in orbit,” said M. Nageswara Rao, Project Director, IRNSS. Its solar panels were deployed. Dr. Rao was confident that the satellite’s life would be longer than the targeted 10 years.

The IRNSS satellites will be useful for land, sea and air navigation. They have civil and defence applications.

None of our political big wigs expressed their appreciation to the ISRO scientists. They are so much preoccupied with their money making devices through gaining membership to the parliament. Shame on them!!!

it is a marvel in engineering to get 25 trips to space with no failures. India should be proud of it.

@Vikram , The main use of having our own navigation satelite is that our
defence forces does not have to depend on american GPS stelites.

Congratulations to all the scientists in ISRO. Navigation satellite is
very much useful in planning the future waterways and safe use of land
and waterways without affecting the envoronment. Hope this is also
achieved by sharing the outputs of this satellite in public domain.

It's really good to know that we will have our own navigation satellites. We need more investments such kind of projects.

Navigation satellite has both commercial and military applications.

It can make car journeys safer and easier.

In times of war we can't rely upon US based systems to help us in navigating our
missiles to destined targets.

Navigational systems have extended uses in locating flights, and improved
organisation of fleets of cars, and buses. They help us in the smooth flow of traffic by
telling the car drivers about congested routes, that could be avoided.

Traffic Police can focus their attention on areas of congestion.

Each and every minute wasted on the road in traffic is an unnecessary waste and
leads to loss of manpower.

One of the most productive and directly useful space application in day to day life is a
navigation satellite.

We shouldn't forget that nothing is gained by avoiding the miracles of modern
technology, as there would be many spin offs that are not apparent to a first time

We can see for ourselves the evolution of internet before our very eyes.

Dear Vikram,
It is not a loss of Tax payer's money. Please google 'benefits of IRNSS'. You might not be knowing that currently all our positioning needs whether military or civilian is met by GPS of USA. Just like USA spied on us, think what he can do by tweaking GPS data.

What a waste of tax payer’s money ! How is this navigation satellite going to be
useful ?

Congrats ISRO! Good to hear such pleasing news at a time when newspapers are filled with news related to corruption, communalism etc

Skyscraper ahead, take diversion!

Research shows that migratory birds follow a "well-informed leader" who guides the flock for a smooth flight around obstacles. »
