New Delhi : ISRO today has launched its Polar Satellite Launch Vehicle (PSLV) off into space from its Spaceport in Sriharikota, Andhra Pradesh. While the entire India was in deep sleep, scientists have blasted off the vehicle at 4:04 am early morning, carrying IRNSS-1I, the eighth satellite for India's native global positioning system. 

Let’s take a look at the important facts PSLV IRNSS-1I, launched by IRSO on April 12, 2018

1.Scientists in Indian Space Research Organisation have declared the 43rd mission of the PSLV a success after it placed the IRNSS 1I satellite into a precise orbit. 

2.The last satellite launch for the satellite-aided navigation NAVIC programme by the PSLV had failed in August 2017, which forced the space agency to design PSLV IRNSS-1I.

3.After the launch, ISRO Chairman Dr K Sivan said, "I am extremely happy to announce that the 8th navigation satellite of India was launched successfully into the NAVIC constellation. We are moving towards a major goal. This NAVIC constellation will create history."

4.The 1,425-kg satellite was made by the Bengaluru-based Alpha Design Technologies, in collaboration with ISRO.

5.IRNSS 1I is a replacement of IRNSS 1H, which was launched last year, on August 31but failed to reach the destination orbit. Earlier, IRNSS 1A, ran into trouble when the atomic clocks onboard the satellite failed one after another

6.The Indian Regional Navigation Satellite System (IRNSS) has the operational name of NAVIC, an acronym for "Navigation with Indian Constellation". 

7.The satellite is designed to be equivalent to the Global Positioning System or GPS which is owned by the US.

8.The NAVIC system is expected to present location tracking within 20 meters of actual positions, especially in the 1,500 km area around the country's borders where the maximum threat sensitivity lies. The satellite launched is meant for both civilian and military uses.

9.The launch of the satellite came two weeks after ISRO’s GSAST 6A communications satellite failure. Sources in the space agency have indicated that a "power systems failure" led to the satellite go absent from where the place it should be. Geosynchronous Satellite Launch Vehicle or GSLV rocket launch on March 29, 2018 made a setback for the space agency as the Rs. 270 crore GSAT 6A that it was carrying was lost due to systems failure.

10.A satellite expert from ISRO confirmed to NDTV that the GSAT 6A was a heavyweight communications satellite and the relatively lightweight IRNSS 1 used a "very different power system", which gave the space agency assurance regarding the successful launch.

It is believed that India felt the need for an indigenous GPS after the Kargil conflict. During the conflict, the country extremely felt the absence of satellite-based navigation system and the American system was not available at the time. For now, with the launch of PSLV IRNSS-1I today, the country can assure to have control and command over its deepest strategic asset.
