Narendra Modi Appreciation to Scientists
New Delhi: Prime Minister Narendra Modi on Thursday congratulated the Indian Space agency on the successful launch of the seventh and final satellite, IRNSS-1G, of Indian Regional Navigation Satellite System (IRNSS) from Sriharikota.The Prime Minister, who himself watched the launch of the PSLV C33/ IRNSS 1G, also congratulated the people.Few minutes into the launch, and congratulating the scientists at ISRO, Modi wrote on the micro-blogging site Twitter:
In space science, our scientists have achieved many accomplishments. Through space science lives of people can be transformed: PM
Pimpri Chinchwad: The first mobile India Space Research Organisation (Isro) exhibition in the state was inaugurated at the science park in Chinchwad on Tuesday by Pramod Kale, ex-director of Space Application Centre, inaugurated it. It will close at 3 pm on Thursday.J P Joshi, retired senior scientist of Isro and associate professor of GSAT 16 and 18 said, “The exhibition has 45 static display panels and four to five interactive working panels, besides three rocket models of PSLV and GSLV Mark III, models of Mangalyan and Chandrayan missions. For the first time, an eminent scientist will have interactive sessions with children on how you can make a career with Isro.”
New Launch By ISRO on GPS New Satellite Costs 1,420 Crore
Exactly at 12.50 p.m. the PSLV rocket standing 44.4 metres tall and weighing 320 tonnes tore into the afternoon skies with fierce orange flames at its tail. And just over 20 minutes into the flight, the PSLV rocket ejected its sole passenger – IRNSS-1F – at an altitude of 488.9 km.
The IRNSS comprising the seven satellites will offer services with much ‘better accuracy’ and targeted position in navigation on par with the Global Positioning System of the United States.
Top 10 ISRO Facts about New GPS Sattelite|Modi Appreciation
- NavIC – or Navigation With Indian Constellation – will be operational within four months and offer a host of services like terrestrial and marine navigation,assistance during disasters, vehicle tracking, fleet management and navigation for drivers.
- Prime Minister Narendra Modi, who watched the launch via a live video link, congratulated the scientists at India’s space agency Indian Space Research Organisation or ISRO.
- “We used to be dependent on others for navigation, today we have become independent. This system is dedicated to our sailors and the world will know it as NavIC,” PM Modi said.
- Currently only five nations have a satellite system offering Global Positioning – the original GPS is owned by the US Air Force and Russia has its parallel system GLONASS.
- China’s BeiDou offers regional coverage. It is being expanded to a global system. Europe’s Galileo, a civil global system, is yet to be operational.
- Each of these satellite systems have between 28 and 35 satellites – a larger number by far compared to the Indian system, which has seven.
- But while most other systems are global or moving towards it, the Indian system is regional in nature. The abbreviated name for the satellite series – IRNSS — stands for Indian Regional Navigation Satellite System.
- “The Indian system will provide positional accuracy of less than 20 meters,” said AS Ganeshan, retired programme director of ISRO’s Satellite Navigation Progamme.
- Officials of ISRO said the cost of building the satellite system was Rs. 1,420 crore.
- The first satellite of the series, IRNSS-1A, was launched in July 2013. Two more satellites were launched the next year. In January and March this year, ISRO placed fifth and the sixth satellites — IRNSS-1E and IRNSS-1F — in space.
According ISRO New Satellite Launch on GPS
According to Indian space agency the applications of IRNSS are: terrestrial, aerial and marine navigation, vehicle tracking and fleet management, terrestrial navigation for hikers and travellers, disaster management, integration with mobile phones, mapping and geodetic data capture and visual and voice navigation for drivers.
In other words, IRNSS could be said to be the “Indian GPS“.
Apart from the civilian applications, the IRNSS will be used for defence purposes as well.
Immediately after the 1,425 kg IRNSS-1G satellite was ejected by the Polar Satellite Launch Vehicle (PSLV-C33) rocket, scientists at the mission control centre clapped their hands happily.
“The launch was succesfull,” Isro chairman A.S.Kiran Kumar said soon after. The Indian Space Research Organisation (Isro) will raise the satellite to its home slot over the next couple of days.
The satellite, with a life-span of 12 years, has two payloads for navigation and ranging.
The navigation payload of IRNSS-1G will transmit signals to the users on the L5-band and S-band. A highly accurate rubidium atomic clock is part of the navigation payload.
The ranging payload consists of a C-band transponder (automatic receivers and transmitters of radio signals) which facilitates accurate determination of the range of the satellite.
An Indian-owned satellite navigation system is crucial to get positional accuracy during war or a war-like situation as the country may be denied such information by countries owing similar systems during such times.
