GSLV-F12 successfully places second gen. navigation satellite into intended orbit: ISRO
Sriharikota, (AP) (PTI): The Indian Space Research Organisation (ISRO) on Monday successfully launched a second generation navigation satellite, using a GSLV rocket with a cryogenic upper stage to do the job.
NVS-01 would augment the country's regional navigation system, providing accurate and real-time navigation.
At the end of a 27.5 hour countdown, the 51.7 metre tall, 3-stage Geosynchronous Satellite Launch Vehicle lifted off at a prefixed time of 10.42 am from the second launch pad at this spaceport, situated about 130 km from Chennai. This was GSLV's 15th flight.
The second generation navigation satellite series dubbed as a significant launch would ensure the continuity of NavIC (Navigation with Indian Constellation) services -- an Indian regional satellite navigation system, similar to the GPS, providing accurate and real-time navigation.
Signals from NavIC are designed to provide user position accurate to better than 20 metres and timing accuracy better than 50 nanoseconds.
ISRO Chairman S Somanath congratulated the entire team for the "excellent outcome" of the mission.
"NVS-01 has been placed in precise orbit by GSLV. Congratulations to the entire ISRO team for making the mission happen," he said in his post-launch address from the Mission Control Center.
Today's success came after the GSLV F10 'debacle,' he said referring to the anomaly in the cryogenic stage of the launch vehicle in August 2021, following which the then mission could not be realised.
He expressed joy that "corrections in cryogenic stage and lessons learnt have really paid benefits" and credited the Failure Analysis Committee for addressing the problem.
Somanath further said NVS-01 is a second generation satellite with additional capabilities. The signals will be more secure, civilian frequency band has been introduced, he said. This was one of the five of such satellites.
The rocket, a little short of 20 minutes after it took off, deployed the 2,232 kg satellite into the intended Geosynchronous Transfer Orbit (GTO) at an altitude of about 251 km.
NVS-01 carried navigation payloads L1, L5 and S bands and the second generation satellite also has an indigenously developed rubidium atomic clock.
It is for the first time that an indigenously developed rubidium atomic clock has been used as the scientists earlier opted for imported ones to determine date and location.
Ahmedabad-based Space Applications Centre has developed the clock, and according to ISRO, it assumes significance as it is an important technology that only a handful of countries possess.
ISRO developed the NavIC system to meet the positioning, navigation and timing requirements of the country, particularly with regard to civil aviation and military requirements.
NavIC was earlier known as the Indian Regional Navigation Satellite System (IRNSS).
"The L1 navigation band is popular for providing position, navigation and timing services for civilian users and for interoperability with other GNSS (global navigation satellite system) signals," ISRO said.
Some of the applications of NavIC include terrestrial, aerial and maritime navigation, precision agriculture, location-based services in mobile devices and marine fisheries, among many others.
NavIC offers two services -- Standard Position Service (SPS) for civilian users and Restricted Service for strategic users.
NavIC SPS signals are interoperable with the US global navigation satellite system signals, GPS, Glonass from Russia, Galileo (European Union) and BeiDou, China.
Monday's mission is the sixth operational flight of the GSLV with indigenous cryogenic stages. The mission life of NVS-01 is expected to be better than 12 years, ISRO said.
ISRO has already launched similar navigation satellites--IRNSS-1A,IRNSS-1B,IRNSS-1C, IRNSS-1D, IRNSS-1E,IRNSS-1F,IRNSS-1G, IRNSS-1H and IRNSS-1I.
Of these missions, IRNSS-1H was not successful as the satellite could not be placed into orbit. It was replaced by IRNSS-1I which was successfully launched on April 12, 2018.

Pranavananda Swamiji urges Cong to make Shivakumar Karnataka CM
Kalaburagi (Karnataka) (PTI): Pranavananda Swamiji, president of the forum of heads of the most backward class maths, urged the Congress high command on Sunday to immediately appoint Deputy Chief Minister D K Shivakumar as the CM of Karnataka.
Warning that the Congress would face “consequences” if Shivakumar is not made CM, he said a group of 25 swamijis plans to visit New Delhi to present the demand to the party high command.
Earlier in the day, Shivakumar said that both he and CM Siddaramaiah will abide by any decision taken by the Congress high command on the leadership issue in the state.
The remarks come amid speculation within the party and political circles about a possible leadership change and cabinet reshuffle after May 4, when the results of assembly elections in four states and one Union Territory, along with bypolls to two assembly segments in Karnataka, are announced.
“The CM chair issue is ongoing in the state. As president of the Mahasabha of swamijis of the most backward class maths in the state, I demand that D K Shivakumar be made CM immediately. It has been about three years since this government came to power, and several timelines have been set, such as Sankranti, Ugadi, and the five-state elections,” Pranavananda Swamiji said.
Speaking to reporters, he said the situation appears to be “insulting” to Shivakumar.
“Shivakumar took over as KPCC president when no one was willing to accept the post and brought the party to power. He was promised the CM post in the presence of AICC President Mallikarjun Kharge, party leader Rahul Gandhi and General Secretary K C Venugopal. Now, why is the party hesitating to fulfil that promise? This is not right,” he said.
Swamiji said he was not denying that Siddaramaiah is a “big leader” of backward communities, but added that Siddaramaiah has already served as CM for about eight years, including five years in his first term.
“We cannot say that backward classes have received significant benefits. Even the recent state budget did not do much for backward class communities,” he said, alleging that these communities have not significantly benefited under Siddaramaiah.
Urging the Congress high command to immediately make Shivakumar the CM, Pranavananda Swamiji warned that otherwise the party would face “serious consequences” in the state.
He said the Mahasabha of swamijis will meet Shivakumar and, after discussions, about 25 swamijis will travel to Delhi.
“Shivakumar’s contribution to most backward communities is immense. He has been an MLA about eight times and a minister several times. Why is he not being given the CM post? He has worked for the party and deserves recognition—this is my demand to the Congress high command,” he added.
The leadership tussle within the ruling party has intensified amid speculation about a possible change of chief minister after the Congress government completed the halfway mark of its five-year term on November 20, 2025.
The speculation has been fuelled by reports of a “power-sharing” arrangement between Siddaramaiah and Shivakumar at the time of government formation in 2023.
