GSAT-14
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. Satellite GSAT-14 is part of the GSAT series of satellites. Constructed by ISRO, it is based around the I-2K satellite bus, and has a dry mass of . With fuel, its mass is . The spacecraft has a design life of 12 years. The satellite carries six Ku-band and six Extended C-band transponders to provide coverage of the whole of India. The satellite is expected to provide enhanced broadcasting services over the GSAT-3 satellite. GSAT-14 also carries two Ka-band beacons which will be used to conduct research into how weather affects Ka-band satellite communications.

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

I-2K
I-2K is a satellite bus developed by Indian Space Research Organisation (ISRO), and marketed by Antrix Corporation. It is a standard bus for 2,000 kg class satellites; the 'I' in I-2K stands for INSAT, a group of communication satellites developed and launched by ISRO. The satellite buses developed by ISRO are specifically developed for small and medium weight satellites. I-2K spacecraft bus can supply DC power up to 3000 watts. I-2K platform is targeted towards satellites in liftoff mass in range of 1500–2500 kg. List of satellites launched using I-2K platform * INSAT series ( 3B 3C 3D 3DR 3E 4C 4CR) * IRS series ( 1C 1D P3) * GSAT series ( 1 2 3 (EDUSAT) 4 5P 6 6A 7 7A 9 14 31) * HYLAS-1 Features of I-2K * Launch Mass: . * Dimensions: 1.65 * 1.53m in plan & 3.0m in height. * Dry Mass: . * Payload Mass: . * Total Power: 2800 W. * Payload Power: 2400 W. * Transponder: 12 - 18. * Mission Life: 12 - 15 Years.

GSAT
The GSAT (Geosynchronous Satellite) 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. History The GSAT series of geosynchronous satellites is a system developed by ISRO with an objective to make India self-reliant in broadcasting services. The repertoire of 10 GSAT satellites, a total of 168 transponders (out of which 95 transponders are leased out to provide services to the broadcasters) in the C, Extended C and Ku-bands provides services to telecommunications, television broadcasting, weather forecasting, disaster warning and search and rescue operations. List of active satellites This is a list of GSAT current satellites with their outcome.

GSAT-16
GSAT-16 is the 11th Indian communication satellite, meant to increase the number of transponders available for satellite-based telecommunication, television, and VSAT services in India. GSAT-16 is similar to GSAT-15 with each satellite weighing 3,150 kg and having power generation capacity of 6.8 kW. Launch Initially launch was planned for 4 December 2014, but was postponed due to inclement weather. GSAT-16 was finally launched on 6 December 2014 from the Guiana Space Centre, French Guiana, by an Ariane 5 rocket. Payload The satellite is equipped with 12 ku, 24 C and 12 Extended C band transponders. The satellite also has the highest Indian ku-beacon transmitter. Satellite GSAT-16 will be the 11th among GSAT series of Indian communication satellites, and will have estimated lifespan of 12 years. It will support civil aviation services apart from backing up the services provided by other communication satellites. The satellite is aimed as a replacement for satellite INSA ...
