This is a list of launches conducted by ISRO using Geosynchronous Satellite Launch Vehicle (GSLV) rockets. This list does not include LVM3 (formerly known as GSLV Mk III) launches, which can be found here.

Notable missions GSLV MK. I flight D1

This was the first developmental flight of the GSLV Mk.I featuring Russian cryogenic engine KVD-1. It was used to place an experimental satellite GSAT-1 into the orbit. However, due to sub-optimal performance and lack of fuel the vehicle did not achieve the intended orbit and the satellite had to maneuver itself using onboard fuel to correct the shortfall. ISRO claims the launch to be successful. In a 2014 interview, ISRO Chairman K. Radhakrishnan attributed the failure to incorrect mixture ratio used in the cryogenic upper stage.

GSLV MK. II flight D5

This was the second test flight with indigenous cryogenic stage CE-7.5 and the first successful launch with the CE-7.5. The flight lifted and successfully placed the GSAT-14 into the orbit. This flight became the harbinger of successful launch with the indigenous cryogenic stage.

GSLV MK. II flight F09

This was the fourth consecutive successful flight of GSLV Mk. II with indigenous cryogenic engine. The flight placed the regional satellite South Asia Satellite was previously named as South Asian Association for Regional Cooperation (SAARC) Satellite. The satellite was a gift from India to its neighbors to bolster Prime Minister Narendra Modi's neighborhood first policy. Afghanistan, Bangladesh, Bhutan, Maldives, Nepal and Sri Lanka are the users of the multi-dimensional facilities provided by the satellite.

Mission outcome

Launch history , rockets from the GSLV family have made 19 launches, resulting in 13 successes, four failures, and two partial failures. All launches have occurred from the Satish Dhawan Space Centre, known before 2002 as the Sriharikota Range (SHAR).

D2 8 May 200311:28 Mk I First GSAT-2 1825 kg GTO INSAT Developmental flight. F01 20 September 200410:31 Mk I First GSAT-3 1950 kg GTO INSAT First operational flight. F02 10 July 200612:08 Mk I Second INSAT-4C 2168 kg GTO INSAT One of the L40 strap-on engines failed at lift-off. Both rocket and satellite had to be destroyed over the Bay of Bengal after the rocket's trajectory veered outside permitted limits. F04 2 September 200712:51 Mk I Second INSAT-4CR 2160 kg GTO INSAT High roll rate build-up due control system malfunction on one L40 strapon resulted in premature shutdown of other strap-on stages. Due to an error in the guidance subsystem achieved orbit had lower apogee and inclination higher than expected. Orbit corrected through satellite, eventually the INSAT-4CR was placed in its slot. Satellite achieved a life of 13 years, 3 months against a planned design life of 12 years . ISRO categorizes this GSLV flight as successful. 2010–2017 Flight No. Date / time (UTC) Rocket,Configuration Launch site Payload Payload mass Orbit User Launchoutcome D3 15 April 201010:57 Mk II Second GSAT-4 2220 kg GTO INSAT First flight test of the ISRO designed and built Cryogenic Upper Stage (CUS). Failed to reach orbit due to malfunction of the Fuel Booster Turbo Pump (FBTP) of the cryogenic upper stage. F06 25 December 201010:34 Mk I Second GSAT-5P 2310 kg GTO INSAT First flight of GSLV Mk.I (c). Aft shroud of upper stage engine bay disintegrated due to aerodynamic loads, snapping the electrical continuity to L40 strapons. Vehicle was destroyed by range safety officer after loss of control over liquid-fueled boosters. D5 5 January 201410:48 Mk II Second GSAT-14 1980 kg GTO INSAT The flight was scheduled for 19 August 2013, but one hour and 14 minutes before the lift off, a leakage was reported and the launch was halted. Second flight of GSLV with indigenous cryogenic upper stage (CUS) developed by ISRO's Liquid Propulsion Systems Centre (LPSC) was launched successfully on 5 January 2014. It was a launch with precision of . All the three stages performed successfully. This was the first successful flight of the cryogenic stage which was developed indigenously in India. D6 27 August 201511:22 Mk II Second GSAT-6 2117 kg GTO INSAT GSLV Mk II D6 with an Indigenous Cryogenic Engine (ICE) successfully ferried GSAT-6 payload into Geostationary Transfer Orbit (GTO) with injection parameters of 170 km x 35945 km, 19.96° inclination. The cuboid-shaped GSAT-6 satellite includes a technology demonstrator S-Band unfurlable antenna with a diameter of six metre which will provide S-band communication services during its expected mission life of nine years. F05 8 September 201611:20 MK II Second INSAT-3DR 2211 kg GTO INSAT First operational flight of GSLV Mk II. The injection parameters were met with extreme precision. Perigee was within 300m (within 0.18%) of the expected value whereas apogee was within 0.2% (80 km). The difference between expected and actual inclination degree was 0.

INSAT-3DR is an advanced atmospheric weather satellite. as well as the second heaviest satellite placed in orbit by an indigenous cryogenic engine propelled GSLVF09 5 May 201711:27 Mk II Second GSAT-9 / South Asia Satellite 2230 kg GTO INSAT South Asia Satellite was previously named as South Asian Association for Regional Cooperation (SAARC) Satellite. 2018 Flight No. Date / time (UTC) Rocket,Configuration Launch site Payload Payload mass Orbit User LaunchOutcome F08 29 March 201811:26 Mk II Second GSAT-6A 2140 kg GTO INSAT Used an enhanced version of the Vikas engine called High Thrust Vikas Engine (HTVE) which had a thrust of in GS2 stage. Electro-hydraulic Actuation used for gimballing in GS2 stage was replaced by more reliable Electro-Mechanical Actuation. F11 19 December 201810:40 Mk II Second GSAT-7A 2250 kg GTO INSAT Used an enhanced version of the Vikas engine called High Thrust Vikas Engine (HTVE) along with uprated cryogenic engine C15. 2021 Flight No. Date / time (UTC) Rocket,Configuration Launch site Payload Payload mass Orbit User LaunchOutcome F1012 August 202100:13 Mk II Second GISAT-1 / EOS-03 2268 kg GTO ISRO Carried EOS-03, a geostationary multi-spectral imaging satellite. The third stage failed to ignite, leading to the loss of the mission. A lower than normal LH2 tank pressure in the cryogenic stage at the time of ignition of the engine resulted in anomalous operation of the Fuel Booster Turbo Pump (FBTP) mounted inside the LH2 tank which feeds the main turbopump of the engine. This in-turn resulted in insufficient flow of Liquid Hydrogen into the engine thrust chamber. The most likely reason for the observed reduction in LH2 tank pressure was a leak in the respective Vent and Relief Valve (VRV), which is used for relieving excess tank pressure during flight. 2023 Flight No. Date / time (UTC) Rocket,Configuration Launch site Payload Payload mass Orbit User LaunchOutcomeF1229 May 202310:42Mk IISecond NVS-01 2232 kgGTOISRONVS-01 is the first in the second generation navigational satellites.

EOS-05 was successfully placed into a sub-geosynchronous transfer orbit of ~171 km perigee and ~31000km apogee by GSLV F17. Apogee attained was ~2000km higher than intended due to higher than expected delta-v given by GSLV launch vehicle.
