GSLV Full Form – Geosynchronous Satellite Launch Vehicle

GSLV Full Form: The GSLV (Geosynchronous Satellite Launch Vehicle) has given a new dimension to India’s space programs. The Indian Space Research Organization (ISRO) has designed and developed the GSLV, powered by indigenous technology and enhanced capacity to launch heavier satellites into the Earth’s geosynchronous orbits.
The successful missions by GLSV demonstrate significant indigenous technological development and self-reliance in space exploration.

This blog explains the GLSV full form, discusses its features and purposes, and helps you recognize its strategic importance in India’s space missions.

GSLV Full Form

The full form of GSLV is Geosynchronous Satellite Launch Vehicle. GSV aims to launch artificial satellites from the Earth and place them in specific geosynchronous orbits.

Satellites in these orbits revolve around the Earth by synchronizing their motion with the Earth’s rotation.

It was a great initiative by the Indian Space Research Organization (ISRO) and a significant step in India’s high-tech endeavour to place heavy satellites in specific orbits for communication and meteorological insights.

GSLV Purposes

The earlier launch vehicles developed by India, the PSLV (Polar Satellite Launch Vehicle), were developed and utilized to place satellites in polar orbits.
PSLV was not powerful enough to place high-capacity, heavier satellites in geosynchronous orbits. ISRO effectively addressed these challenges by designing GSLV, which is capable of launching heavy INSAT satellites.

It has a payload capacity ranging from 2,250 kgs (for GS orbits) to 6000 kgs (for lower Earth orbits).

GSLV History

The successful implementation of GSLV has evolved through different stages. Here are the important milestones in the GSLV development:

• 1990s: ISRO started working on the GSLV project.
• 2000: Experimental launch of GSLV carrying GSAT-1 satellite
• 2001: The first successful flight of GSLV was performed on April 18, 2001.
• 2014: GSLV-D5 with an indigenous cryogenic engine was launched successfully.

Between 2015 and 2025, India completed 9 successful launches of GSLV to place GSAT, INSAT, and NVS satellites on the geosynchronous transfer orbits (GTO).

GSLV Features

GSLV is a fourth-generation launch vehicle that can place satellites at higher orbits and uses an advanced cryogenic engine that works on liquid oxygen and hydrogen. The GSLV features are mentioned below:

Three-stage Configuration

The GSLV is designed with a three-stage configuration as follows:

• 1st stage: It consists of solid fuel and liquid boosters
• 2nd stage: It contains liquid fuel
• 3rd stage: It is the cryogenic stage containing cooled liquid oxygen and hydrogen

Cryogenic Engine

A cryogenic engine burns fuel at extremely low temperatures, producing more thrust and allowing the rocket to carry heavy loads. India developed an indigenous cryogenic engine, which is a great achievement.

Higher Payload Capacity

GSLV can carry higher payloads compared to PSLV. This feature has enabled India to send heavier, advanced satellites to space and place them on geosynchronous transfer orbits (GTO).

GSLV Types

There are different types of GSLV designed so far. Let’s have a look at them:

• GSLV Mk I: It is the preliminary version of GSLV with a payload capacity of around 1500 kg satellites to GTO. It used a Russian cryogenic stage as India was not ready with its cryogenic technology. This type of GSLV was used to launch 5 satellites from 2001 to 2010.
• GSLV Mk II: It is the enhanced version powered by an indigenously developed cryogenic upper-stage engine. It can carry payloads of up to 2500 kg. Since the first successful launch in 2014, India has carried out 4 launches with this vehicle.
• GSV Mk III: This latest version of GSLV, also known as LVM-3, is the most advanced type of launch vehicle. It can carry payloads up to 4 tons. It has been used in some significant missions like Chandrayaan-2.

GSLV Missions

The GSLV has contributed significantly to India’s space program by launching important communication and navigation satellites into Earth’s orbit. Here’s an overview of some important GSLV missions:

• Chandrayaan-2: This lunar mission uses GSLV Mk III, demonstrating GSLV’s capability in more advanced space exploration.
• GSAT series: The GSLV has been used to launch various GSAT communication satellites, which play a significant role in India’s telecommunications and broadcasting infrastructure.
• NVS series: The GSLV has launched satellites like NVS-01 and NVS-02, part of the second-generation Indian Regional Navigation Satellite System (IRNSS).
• OneWeb Missions: The GSLV Mk III has been used for commercial launches of OneWeb satellites. It helps expand India’s capability in the global space market.
• Gaganyaan: The GSLV Mk III is chosen as the launch vehicle for India’s ambitious human spaceflight program Gaganyaan.
• GSLV-F15: ISRO’s 100th launch from Shriharikota successfully placed the NVS-02 satellite into orbit.
