INSAT-4A was the first one in the INSAT-4 Satellites series, providing services in the Ku and C band frequency bands. At the time of launch, it was the heaviest satellite India had produced. The Ku transponders cover the Indian main land and C-Band transponders cover an extended area. It has a dozen Ku transponders and another dozen of C-band transponders. This spacecraft was placed at 83°E along with INSAT-2E and INSAT-3B, by Ariane launch vehicle (ARIANE5-V169). [3] [4] [5] [6]

Overview

INSAT-4A was a communication satellite intended for providing high quality television, telecommunication, broadcasting services and was the first satellite to be launched in the INSAT-4 series.

Launch

INSAT-4A was launched by an Ariane 5, produced by Arianespace, on 21 Dec 2005 at 22.33 UTC [7] [8] from Kourou, French Guiana. It was placed into a Geosynchronous Transfer Orbit (GTO), 30 minutes after lift-off in 3-axis stabilized mode, with a perigee of 859 km and an apogee of 36,055 km. Its co-passenger on board was Meteosat-9 of EUMETSAT.

Payload

End Of Life and Replacement

The satellite was placed in the graveyard orbit on 21 October 2019 after almost 14 years in service. [2] A replacement satellite GSAT-30 was launched on 21:05 UTC, 16 January 2020 aboard Ariane 5 VA251. [9] [10]

INSAT-3C is a multipurpose satellite built by ISRO and launched by Arianespace in Jan 2002. INSAT-3C is the second satellite of the INSAT-3 series. All the transponders provide coverage over India. Insat-3C is controlled from the Master Control Facility at Hassan in Karnataka. It will provide voice, video and digital data services to India and neighboring countries.

INSAT-4CR was a communications satellite operated by ISRO as part of the Indian National Satellite System. Launched in September 2007, it replaced the INSAT-4C satellite which had been lost in a launch failure the previous year. The satellite was initially stationed in geostationary orbit at a longitude of 74 degrees east, with expected operational life of at least ten years, however this may have been reduced by the underperformance of the Geosynchronous Satellite Launch Vehicle which placed it into orbit. INSAT-4CR is planned to be replaced by GSAT-31, which was launched on February 6, 2019.

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.

GSAT-7 or INSAT-4F is a multi-band military communications satellite developed by the Indian Space Research Organisation. The Indian Navy is the user of the multi-band communication spacecraft, which has been operational since September 2013. According to defense experts, the satellite will enable the navy to extend its blue water capabilities and stop relying on foreign satellites like Inmarsat, which provide communication services to its ships.

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.
