The GSAT-12 communication satellite, launched onboard PSLV-C17, has been successfully placed in geosynchronous orbit with a perigee of 35,684 km, apogee of 35,715 km and an orbital inclination of 0.17 deg with respect to the equatorial plane.
India's advanced multi-band communication satellite GSAT-7, launched from French Guiana by European space consortium Arianespace's Ariane 5 rocket on August 30, has been successfully placed in the geosynchronous orbit with an altitude of about 36,000 km above earth's surface.
ISRO has successfully launched EOS-05, India's first geo-imaging satellite, into a precise sub-geosynchronous transfer orbit using a GSLV rocket. This 2,367 kg satellite, the heaviest ever carried by a GSLV, will provide real-time imagery for applications in agriculture and disaster management from an altitude of 36,000 km.
It is about proving that the agency can still deliver when the stakes are high.
'It is not economical to operate GSLV-Mk II due to its cost and complexity. Future launches to be managed with LVM3.'
Buying a mature rocket technology gives companies the designs and hardware know-how, but not necessarily the decades of engineering wisdom needed to make it work.
'It is to observe the Sun continuously that you have the Aditya L1 mission.' 'It is in a position from where it can observe the Sun continuously.'
The heaviest communication satellite to be launched from the Indian soil onboard a new generation, homegrown 'Bahubali' rocket was successfully placed into the intended orbit on Sunday, the Indian Space Research Organisation said.
The EoI comes at a time when ISRO is working to enhance LVM3's payload capacity to five tonnes in GTO and is also evaluating the procurement of a Russian semi-cryogenic engine for the vehicle's second stage.
ISRO stated that the disengagement of at least one contact -- in both the main and redundant paths -- of a connector led to the failure of NVS-02.
A high-level committee investigating the failures of ISRO's PSLV rockets, which have impacted strategic satellite missions, has yet to release its report and recommendations, raising concerns about the future of the ageing launch vehicle.
The need for NavIC was cemented after India was denied access to crucial navigation data from global providers during the 1999 Kargil War.
Weighing 6,100 kg, the communication satellite would be the heaviest payload to be placed into the Low Earth Orbit (LEO) in LVM3 launch history from Indian soil.
ISRO is developing a third launch pad at Shriharikota to accommodate heavier satellites and next-generation launch vehicles. The new facility will support both crewed and uncrewed missions.
The move follows a quiet visit by National Security Advisor Ajit Kumar Doval to the Vikram Sarabhai Space Centre in Thiruvananthapuram.
'The work is already on with various data being studied.'
The satellite, weighing about 4,410 kg will be the heaviest to be launched from the Indian soil and into a Geosynchronous Transfer Orbit (GTO), the space agency said. The satellite will travel onboard a LVM3-M5 rocket, dubbed as 'Bahubali' for its heavylift capability.
These upcoming launches carry added significance in light of setbacks suffered in recent years.
ISRO is set to launch its communication satellite CMS-03 from Sriharikota. The satellite, weighing 4,410 kg, will be the heaviest launched from Indian soil into a Geosynchronous Transfer Orbit (GTO).
ISRO's vendor policy and quality control processes are under scanner.
'A solid motor, once ignited, burns until the propellant is exhausted. It cannot simply stop mid-burn,' said a retired senior ISRO official. 'That is what makes this failure puzzling.' Venkatachari Jagannathan reports on the latest PSLV failure.
ISRO chairman S Somanath said the success gave the space agency "greater confidence," as the GSLV will be next deployed in the NISAR mission, a collaborative effort with the US' NASA.
The Propulsion Module (PM) of Chandrayaan-3 has been moved from an orbit around the Moon to an orbit around Earth, the Indian Space Research Organisation (ISRO) has said, terming the operation a unique experiment.
The ISRO on Sunday scripted yet another history after its LVM3 rocket successfully placed 36 satellites of United Kingdom-based OneWeb group company into intended orbits.
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.
The satellite has reached its final slot and will be fully operational by the month-end.
In terms of success rate, the PSLV rocket has an enviable record of 57 successful missions out of 58 commercial ones.
The imaging technology in Nisar can provide very high-resolution data on changes as small as one centimetre in size on the earth's surface.
The main focus of the all weather RISAT-1B satellite will be to observe the Indian land with its C-band synthetic aperture radar.
A PSLV rocket carrying Earth observation satellite EOS-09 failed to launch from the Sriharikota spaceport early on Sunday.
India is set to launch in a month its powerful rocket with a homemade cryogenic engine to propel a satellite into a geosynchronous orbit and become only the sixth nation to develop this complex engine.The much awaited launch has been billed as a landmark event for the country's space programme after its maiden unmanned moon mission Chandrayaan-I in 2008.India had been using Russia-made cryogenic engines so far for satellite launchings.
At 6.23 am on 29.1.2025, the 50.9 metre tall and weighing 420.7 ton Geosynchronous Satellite Launch Vehicle-F15 (GSLV-F15) is slated to blast off from the second launch pad carrying the 2,250 kg NVS-02 navigation satellite.
'The satellite's condition is healthy.'
The Indian Space Research Organisation will open 2025 scoring a century orbiting the country's navigation satellite 2,250 kg NVS-02 with its rocket Geosynchronous Satellite Launch Vehicle (GSLV)-F15.
The Indian Space Research Organisation successfully launched its 100th mission on Wednesday, with a GSLV rocket carrying navigation satellite NVS-02.
NISAR will not be used for surveillance and will be used to observe the earth.
Twice every 12 days, the NISAR satellite will scan nearly all of earth's land and ice surfaces to measure changes in the planet's ecosystems, growth and retreat of its land and sea ice, and deformation of its crust.
All spacecraft parameters are normal, the Bengaluru headquartered space agency said after the maneuver on the spacecraft.
