The GSAT-14 mission marked a significant step forward for ISRO, with the satellite being placed in a geostationary transfer orbit and eventually reaching its final destination at 73.9E. This achievement showcases the space agency's capabilities and expertise.

The mission's core operational phase was designed to last for 12 years, with the satellite providing continuous communication services during this time.

The Satish Dhawan Space Centre is located in Sriharikota, Andhra Pradesh, India. It's a crucial launch site for ISRO's missions.

This centre is named after the renowned Indian space scientist Satish Dhawan. He played a significant role in India's space program.

ISRO has launched several satellites and spacecraft from this centre, including the Chandrayaan-1 mission to the Moon.

The GSAT-14 mission was launched on January 5, 2014, after several delays. It was launched on the GSLV rocket, which placed the satellite in a geostationary transfer orbit.

The satellite's mass is 1,982 kilograms with fuel, and 851 kilograms without fuel. It has a design life of 12 years. The spacecraft is based on the I-2K bus.

The GSAT-14 satellite carries six Ku-band and six Extended C-band transponders for communication purposes. It also carries two Ka-band beacons for a propagation study.

The ISRO GSAT-14 mission was launched on January 5, 2014, with a mass of 1982 kg. The spacecraft is based on the I-2K satellite bus and has a dry mass of 851 kilograms.

The mission's communication suite is formed by C-band and Ku-band frequencies. The satellite carries six Ku-band and six Extended C-band transponders to provide coverage of the whole of India.

GSAT-14 is powered by two solar arrays, generating 2,600 watts of power. The satellite has a design life of 12 years and is expected to operate in orbit for the same duration.

Here are the key technical specifications of the GSAT-14 mission:

The satellite is equipped with advanced technologies such as fibre optic gyro, active pixel Sun sensor, round type bolometer, and field programmable gate array based Earth sensors and thermal control coating experiments.

Propellants in GSLV Stages are crucial for the mission's success. The three stages of GSLV use a combination of propellants to achieve the desired performance.

HTPB, a type of rubber-like fuel, is used in the first stage of GSLV. HTPB is a common propellant used in many rocket systems.

Liquid oxygen at minus 183 degrees Celsius is used in the second stage of GSLV. This cryogenic propellant is extremely cold and requires specialized storage and handling.

Liquid hydrogen at minus 253 degrees Celsius is also used in the second stage of GSLV. This propellant is used in conjunction with liquid oxygen to provide a high specific impulse.

Unsymmetrical Dimethyl Hydrazine + 25% Hydrazine Hydrate is used in the third stage of GSLV. This propellant combination is a common choice for high-performance rocket applications.

The use of cryogenic propellants in GSLV allows for a high degree of precision and control during the mission.
