ISRO launches 7th and final satellite IRNSS-1G on  April 28, 2016

Prime Minister Narendra Modi lauded the scientists and congratulated the people of the country on the achievement saying, “with this successful launch, we will determine our own paths powered by our technology”.

“The world will know it as Navic.... The new technology will benefit our people, our fishermen. This is a great gift to people from scientists,” Modi said.
According to ISRO officials, the total cost of all the seven satellites was Rs 1,420 crore.
For today’s mission, ISRO used the PSLV-XL variant which has six solid strap-on motors to augment the thrust provided by the first stage, making the rocket powerful.

The XL variant was used during the launch of Mars Orbiter Mission, Chandrayaan-1, ASTROSAT besides the six earlier IRNSS satellites.

IRNSS-1G which has a 12-year mission life would become operational in about a month’s time, marking the full-fledged functioning of the IRNSS.

With the operations of six satellites, so far, India demonstrated a targeted position of accuracy much better than 20 metres above earth and round-the-clock.
