The GSAT-12 launch was a significant event in India's space program, marking the 18th straight success for the Polar Satellite Launch Vehicle (PSLV). The launch took place on July 15, 2011, from the Satish Dhawan Space Centre at Sriharikota Island.

The PSLV configuration used for the launch included six strap-on motors, each carrying 12 metric tons of solid propellant. This configuration was chosen due to the PSLV's reliability and success in launching low Earth orbiting remote sensing satellites.

The GSAT-12 mission was a critical step in ensuring continuity of communication services, particularly in the face of two consecutive failures of the more powerful Geostationary Satellite Launch Vehicle in 2010.

Here are some key statistics about the GSAT-12 launch:

The Indian Space Research Organisation (ISRO) successfully launched its latest communications satellite, GSAT-12, aboard its Polar Satellite Launch Vehicle (PSLV) on July 15, 2011.

The launch took place at 4:48 p.m. local time from the Satish Dhawan Space Centre at Sriharikota Island off India's southeastern coast.

GSAT-12 was deployed into a geostationary transfer orbit with a perigee of 284 kilometers and an apogee of 21,000 kilometers. The liquid-fueled apogee motor would be used to place the craft in a circular geostationary orbit 36,000 kilometers above the equator.

The PSLV configuration used for the launch consisted of six strap-on motors, each carrying 12 metric tons of solid propellant.

This was the 18th straight success for the PSLV, which normally is used to launch low Earth orbiting remote sensing satellites.

Here is a summary of the launch vehicle specifications:

The GSAT-12 satellite had a planned operational life extending to around 7 years and was equipped with 12 extended C-band transponders to partly meet the country's growing demand for transponders in a short turnaround time.

The satellite was designed to provide communication services, including VSAT, DTH, and tele-education, tele-medicine services.

The mission was a significant achievement for ISRO, demonstrating its capability to launch satellites into geostationary orbit using the PSLV.

The Satish Dhawan Space Centre is a vital part of India's space program, located in Sriharikota, Andhra Pradesh. It's situated near the Bay of Bengal, which provides a unique environment for rocket launches.

The centre is named after Satish Dhawan, a renowned Indian space scientist who played a key role in India's space program. He was the chairman of the Indian Space Research Organisation (ISRO) from 1972 to 1984.

The Satish Dhawan Space Centre is home to the second launch pad, which has been used for several successful satellite launches. It's also been the site of several rocket failures, including the loss of the Polar Satellite Launch Vehicle (PSLV) in 2010.

The centre has a strong focus on satellite launches, with many of its launches carrying communications satellites into orbit. These satellites provide critical communication services to India and other countries in the region.

The Satish Dhawan Space Centre has a significant role in India's space program, with many of its launches contributing to the country's growth and development.

The Indian Space Research Organisation (ISRO) successfully launched the GSat-12 communications satellite on July 15, 2011, aboard the Polar Satellite Launch Vehicle (PSLV).

The GSat-12 satellite was equipped with 12 extended C-band transponders, which would partly meet India's growing demand for transponders in a short turnaround time.

ISRO chose the PSLV for the GSat-12 launch after two consecutive failures of its more powerful Geostationary Satellite Launch Vehicle in 2010.

The GSat-12 satellite has a design life of eight years and was placed in a circular geostationary orbit 36,000 kilometers above the equator.

ISRO completed the post-mission disposal operation of the GSat-12 satellite on March 23, 2023, by raising its orbit above the geostationary altitude of 35,786 kilometers.

A series of seven manoeuvres were carried out to raise the orbit, followed by four inclination changing manoeuvres to spend the remaining propellant.

The final passivation manoeuvre was carried out to vent out the remaining fuel, and all rotating mechanisms, such as momentum wheels, reaction wheels, and gyros, were turned off.

The GSat-12 satellite is the 23rd GEO satellite to undergo post-mission disposal before decommissioning, and the operation was fully compliant with the IADC and UN space debris mitigation guidelines.

India's GSat-12 telecommunications satellite was launched on July 15, 2011, aboard the Polar Satellite Launch Vehicle (PSLV).

The satellite has a design life of eight years and will be co-located with ISRO's Insat-2E and Insat-4A satellites at 83 degrees longitude.

GSat-12's liquid-fueled apogee motor will be used to place the craft in a circular geostationary orbit 36,000 kilometers above the equator.

Here's a summary of the launch:

The PSLV's dependability was a key factor in choosing it for this mission, especially after two consecutive failures of the more powerful Geostationary Satellite Launch Vehicle in 2010.
