The GSAT-31 is a 'high power' communication satellite going to serve and replace some of the satellites that are going to expire soon.
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 PSLV rocket carrying Earth observation satellite EOS-09 failed to launch from the Sriharikota spaceport early on Sunday.
The 3,357-kg satellite, which was deployed from the lower passenger position of Ariane-5 launch vehicle (VA 251) into the geostationary transfer orbit, is configured on ISRO's enhanced I-3K Bus structure to provide communication services from Geostationary orbit in C and Ku bands.
GSAT-18, which aims at providing telecommunications services for the country by strengthening ISRO's current fleet of 14 operational telecom satellites, was launched into a Geosynchronous Transfer Orbit about 32 minutes after the lift-off.
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 successfully launched its 100th mission on Wednesday, with a GSLV rocket carrying navigation satellite NVS-02.
A high power satellite, GSAT-15 is being inducted into the INSAT/GSAT system. GSAT-15 carries a total of 24 communication transponders in Ku-band as well as a GPS-Aided GEO Augmented Navigation (GAGAN) payload operating in L1 and L5 bands.
'The work is already on with various data being studied.'
In terms of success rate, the PSLV rocket has an enviable record of 57 successful missions out of 58 commercial ones.
The Indian space agency has already begun work on the third generation of the earth observation satellite -- the first of which will be ready by 2018 and boost the capability to generate digital maps.
There was no major design flaw in the Indian Space Research Organisation's Geostationary Satellite Launch Vehicle, which crashed seconds after take-off on December 25 last year, said a fact- finding panel.
It also carries equipment for meteorological data relay and satellite based search and rescue services being provided by earlier INSAT satellites.
The earth observation satellite would provide real-time images of the country and also be able to quickly monitor natural disasters.
ISRO is part of an exclusive league which has forayed into the Moon and Sun.
The 3,423 kg GSAT-29 carries Ka and Ku band high throughput transponders intended to meet the communication requirements of users, including in the North East and in Jammu and Kashmir.
The satellite will enable a full range of services to neighbours including the areas of telecommunication, television, direct-to-home, VSATs, tele-education and tele-medicine.
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.
Except Pakistan, seven SAARC countries are a part of the project.
The 3,357-kg satellite is slated to blast off from the Ariane Launch Complex at Kourou, a French territory located along the northeastern coast of South America, at 02:35 hrs IST. "GSAT-30 is to serve as a replacement to INSAT-4A spacecraft services with enhanced coverage", ISRO said.
The mission life of the 2,250kg GSAT-7A, built by ISRO, is eight years. It will provide communication capability to users in Ku-band over the Indian region.
According to the Indian Situational Space Awareness Report for 2023, the nominal lift-off of the Launch Vehicle Mark-3, carrying the Chandrayaan-3 spacecraft, had to be delayed by four seconds based on the Collision on Launch Avoidance analysis.
GSLV Mark-III will be India's most powerful launch vehicle built to lift the heaviest Indian communications satellites to space.
In a landmark late Monday night journey into a new era of space application, India successfully launched its first dedicated navigation satellite using the Polar Satellite Launch Vehicle which blasted off from the Satish Dhawan Space Centre.
ISRO Chairman K Sivan described the GSAT-11 as the "richest space asset" for India.
The satellite would provide a thrust to mobile communication through multi-beam coverage facility, the ISRO said.
The rocket can put satellites weighing upto four tonnes in space, double the weight that the current GSLV-Mark-II can lift.
The feat is the second one for the Indian Space Research Organisation scientists in using the indigenously made cryogenic stage after the January 5, 2014 launch of GSLV-D5.
'When a Project Director is appointed, the whole organization -- including the Chairman ISRO -- works for his success. It is a lesson that has been of abiding value all through the other projects I have worked on,' recalls the late President, one of the earliest pioneers at ISRO.
Other than the Cartosat-2 series satellite, the PSLV is carrying 29 nano satellites from 14 countries - Austria, Belgium, Chile, Czech Republic, Finland, France, Germany, Italy, Japan, Latvia, Lithuania, Slovakia, the United Kingdom and the United States of America besides a nano satellite from India.
It is important for India to develop multiple launch sites and become capable of undertaking more launches in a year's time, says Ajey Lele.
The satellite was placed at 4.18 pm, a little over 17 minutes after the Geosynchronous Satellite Launch Vehicle (GSLV-F-01) carrying it was launched from the Satish Dhawan Space Centre in Sriharikota.
GSLV-MK III, which uses a homegrown cryogenic engine, has to do at least two more launches before it begins commercial operations, report Raghu Krishnan and T E Narasimhan.
Weighing about 5,854 kg, GSAT-11 would play a vital role in providing broadband services across the country, and also provide a platform to demonstrate new generation applications.
ISRO Chairman K Sivan said there might by a postponement if the weather was not conducive.
The 43.43 metre tall rocket lifted off at 5.28 pm from the second launch pad at the Satish Dhawan Space Centre in Sriharikota
Indian Space Research Organisation plans to undertake next month the first developmental flight of a "game-changer" rocket capable of launching four-ton class of satellites from Sriharikota spaceport, says its Chairman A S Kiran Kumar.
The 'context' of the launch of GSAT-15 highlights that India has much ground to cover in the transponder arena while in satellite navigation arena ISRO's progress has been satisfactory, says Ajey Lele.
A truly 'made in India' satellite that will empower a digital India.
