GSAT-20 (also known as CMS-03 or GSAT-N2) is a communication satellite jointly being developed by Indian Space Research Organisation Satellite Centre and Liquid Propulsion Systems Centre [5] and will be launched by a SpaceX Falcon 9. [6] The GSAT-20 satellite is funded, owned and operated by New Space India Limited. [7] The entire capacity onboard CMS-02 satellite will be leased to Dish TV. [8] [9] 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.
It will be the first fully Electric Propulsion/EP enabled satellite which can be five to six times more efficient than chemical-based propulsion. [5] It will be the first ISRO made satellite to move from Geostationary transfer orbit to Geosynchronous orbit using Electric Propulsion. [10]
The satellite features a Ka-band high-throughput communications payload with 70 Gbit/s [11] throughput utilizing 40 beams offering HTS capacity of nearly 48Gpbs. [12] Each beam will have 2 polarisations, effectively making them 80 beams. [13]
The satellite was initially expected to be launched in 2024 on an LVM 3, [3] [14] [15] but shifted to Falcon 9 due to the satellite being 700 kilos overweight for a successful launch on indigenous platforms. [16]
Hence ,The commercial arm of ISRO ,New Space India Limited has signed a contract with SpaceX for a possible liftoff in the second quarter of 2024. The SpaceX deal also signifies a significant as till now India had relied heavily on the France led Arianespace consortium to launch its the heavy communication satellites , particularly on the now retired Ariane 5, which ISRO was hoping as a backup. The fact that the next few launches of the Ariane 6, its successor having being both booked and delayed for launch, ISRO turned to SpaceX. India's own rockets lack the capacity for launching very heavy satellites to the geostationary orbit beyond 4 ton class, a problem that is planned to be fixed with the introduction of the NGLV.

The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).
The Indian National Satellite System or INSAT, is a series of multipurpose geostationary satellites launched by the Indian Space Research Organisation (ISRO) to satisfy telecommunications, broadcasting, meteorology, and search and rescue operations. Commissioned in 1983, INSAT is the largest domestic communication system in the Indo-Pacific Region. It is a joint venture of the Department of Space, Department of Telecommunications, India Meteorological Department, All India Radio and Doordarshan. The overall coordination and management of INSAT system rests with the Secretary-level INSAT Coordination Committee.
Geosynchronous Satellite Launch Vehicle (GSLV) is a class of expendable launch systems operated by the Indian Space Research Organisation (ISRO). GSLV has been used in fifteen launches since 2001.
The Indian Space Research Organisation is the national space agency of India. It operates as the primary research and development arm of the Department of Space (DoS), which is directly overseen by the Prime Minister of India while the Chairman of ISRO also acts as the executive of DoS. ISRO is primarily responsible for performing tasks related to space-based operations, space exploration, international space cooperation and the development of related technologies. ISRO is one of the six government space agencies in the world that possesses full launch capabilities, can deploy cryogenic engines, can launch extraterrestrial missions and operate a large fleet of artificial satellites. ISRO is one of the four government space agencies to have soft landing (unmanned) capabilities.
The GSAT satellites are India's indigenously developed communications satellites, used for digital audio, data and video broadcasting. As of 5 December 2018, 20 GSAT satellites of ISRO have been launched out of which 14 satellites are in service.
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.
GSAT-11 is an Indian geostationary communications satellite. The 5854 kg satellite is based on the new I-6K Bus and carry 40 transponders in the Ku-band and Ka-band frequencies, which are capable of providing up to 16 Gbit/s throughput. GSAT-11 is India's heaviest satellite.
INSAT-4E, also known as GSAT-6, is a member of the INSAT family and is a multimedia communication satellite that will offer a Satellite Digital Multimedia Broadcasting (S-DMB) service across several digital multimedia terminals or consoles which can be used to provide information services to vehicles on the fly and to the mobile phones. The satellite can be used for other social and strategic applications.
GSAT-15 is an Indian communication satellite similar to GSAT-10 to augment the capacity of transponders to provide more bandwidth for Direct-to-Home television and VSAT services. It was successfully launched on 10 November 2015 at 21:34:07 UTC aboard an Ariane 5 rocket, along with the ArabSat 6B satellite.
The South Asia Satellite, formerly known as SAARC Satellite, is a geostationary communications and meteorology satellite operated by the Indian Space Research Organisation for the South Asian Association for Regional Cooperation (SAARC) region. The satellite was launched on 5 May 2017. During the 18th SAARC summit held in Nepal in 2014, Indian Prime Minister Narendra Modi mooted the idea of a satellite serving the needs of SAARC member nations as a part of his neighbourhood first policy. Afghanistan, Bangladesh, Bhutan, Maldives, Nepal and Sri Lanka are the users of the multi-dimensional facilities provided by the satellite.
GSAT-19 is an Indian communications satellite launched by the Indian Space Research Organisation aboard an LVM3 on 5 June 2017.
