GSAT-29 is a high-throughput communication satellite developed by the Indian Space Research Organisation (ISRO). [4] [5] The mission aims at providing high-speed bandwidth to Village Resource Centres (VRC) in rural areas. [6] The two Ku and Ka operational payloads will provide communication services to Jammu and Kashmir and Northeast India under Digital India programme. [7] At the time of launch GSAT-29 was the heaviest satellite, weighing 3,423 kg (7,546 lb), [8] that was placed in orbit by an Indian launch vehicle. [9] [10] Approved cost of GSAT-29 is ₹175.63 crore (US$22 million). [11]

The satellite was launched on 14 November 2018 through the second developmental flight of GSLV Mk III, [16] that placed the GSAT-29 satellite into its planned geosynchronous transfer orbit (GTO) over the equator. [17] It joins the Indian National Satellite System (INSAT) fleet in geostationary orbit. [10]

The Launch Vehicle Mark-3 or LVM3 is a three-stage medium-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). Primarily designed to launch communication satellites into geostationary orbit, it is also due to launch crewed missions under the Indian Human Spaceflight Programme. LVM3 has a higher payload capacity than its predecessor, GSLV.

<span class="mw-page-title-main">GSAT-4</span>

GSAT-4, also known as HealthSat, was an experimental communication and navigation satellite launched in April 2010 by the Indian Space Research Organisation on the maiden flight of the Geosynchronous Satellite Launch Vehicle Mk.II rocket. It failed to reach orbit after the rocket's third stage malfunctioned. The third stage was the first Indian-built cryogenic-fuelled upper stage, and was making its first flight. The ISRO suspects that the failure was caused by the third stage not igniting.

GSAT-5P, or GSAT-5 Prime, was an Indian communications satellite which was lost in a launch failure in December 2010. Part of the Indian National Satellite System, it was intended to operate in geosynchronous orbit as a replacement for INSAT-3E.

GSAT-14 is an Indian communications satellite launched in January 2014. It replaced the GSAT-3 satellite, which was launched in 2004. GSAT-14 was launched by a Geosynchronous Satellite Launch Vehicle Mk.II, which incorporated an Indian-built cryogenic engine on the third stage.

GSAT-10 is an Indian communication satellite which was launched by Ariane-5ECA carrier rocket in September 2012. It has 12 KU Band, 12 C Band and 6 lower extended c band transponders, and included a navigation payload to augment GAGAN capacity. Following its launch and on-orbit testing, it was placed in Geosynchronous orbit at 83.0° East, from where it will provide communication services in India.

<span class="mw-page-title-main">GSAT-6A</span>

GSAT-6A was a communication satellite launched by the Indian Space Research Organisation (ISRO) It featured a 6-metre (20 ft) unfurlable S-band antenna similar to the one used on GSAT-6. Around 17 minutes after lift-off, the three stage GSLV Mk.II rocket flying on GSLV F08 mission successfully injected the satellite into a geosynchronous transfer orbit. Due to power failure during its orbit raising burns the communication was lost with GSAT-6A before it could reach its final circular geostationary orbit (GSO).

GSAT-20 is a communication satellite jointly being developed by Indian Space Research Organisation Satellite Centre and Liquid Propulsion Systems Centre and will be launched by ISRO. GSAT-20 will be a continuation of GSAT series of communication satellites. The satellite is intended to add data transmission capacity to the communication infrastructure required by Smart Cities Mission of India.
