INSAT 3E is a defunct communication satellite built by Indian Space Research Organisation. It was launched on September 28, 2003, from the European Space Agency's spaceport in French Guiana on board the Ariane rocket. The satellite had a launch mass of 2750 kilograms. It is the 4th satellite launched in the INSAT-3 series for INSAT. It was designed for providing high-speed communication, Television, VSAT & Tele-education services and was an important landmark in Indian Space Programme.

In April 2014, almost eleven years after being launched, the satellite ran out of oxidizer and a few days later, was decommissioned by the ISRO. A few days later, it was moved into a graveyard orbit. [3]

Launch

INSAT 3E was launched from Kourou, French Guiana on September 28, 2003, on European consortium Ariane space's Ariane 5-V162 launcher along with two other satellites viz. Eurobird 3 of Eutelsat and SMART-1 of European Space Agency at 4.44 am IST.It was placed into a geosynchronous transfer orbit 30 minutes after the lift-off, in 3-axis stabilised mode, with a perigee of 649 km and an apogee of 35,923 km and an inclination of 7 deg. with respect to the equator. Its master control facility is at Hassan, Karnataka (India).

Payload

INSAT 3E payload consists of C-band and extended C-band transponders. It has 24 C-band transponders, having India beam coverage providing an Edge Of Coverage-Effective Isotropic Radiated Power (EOC-EIRP) of 38.5 dBW and 12 upper extended C-band transponders having India beam coverage providing an EOC-EIRP of 38 dBW.

Retirement

On April 1, 2014, Dr. K. Radhakrishnan, while speaking to the Indian English newspaper "The Hindu", said that INSAT 3E had been decommissioned. The newspaper reported that a few days before, the satellite had run out of the on-board oxidizer, which is essential to burn the fuel that kept it Earth-locked (fixed over India) and running its daily functions. The ISRO had apparently expected that the satellite, positioned at 55 degrees E longitude, would last a few more months and that it would be smoothly replaced with GSAT-16. The Master Control Facility at Hassan moved the expired satellite into a graveyard orbit a few days after. [3]

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.

The Master Control Facility (MCF) is a facility set up by the Indian Space Research Organisation (ISRO) in the city of Hassan in the Indian state of Karnataka. Established in 1982, this facility is responsible for monitoring and controlling geostationary and geosynchronous satellites launched by ISRO. This was the only Master Control Facility of ISRO till another one was established in Bhopal in 2005.

INSAT-3B is an Indian communications satellite which was built by the Indian Space Research Organisation and operated by Indian National Satellite System. It's the first Geostationary satellite by India.

INSAT-3D is a meteorological, data relay and satellite aided search and rescue satellite developed by the Indian Space Research Organisation and was launched successfully on 26 July 2013 using an Ariane 5 ECA launch vehicle from French Guiana. The satellite has many new technology elements like star sensor, micro stepping Solar Array Drive Assembly (SADA) to reduce the spacecraft disturbances and Bus Management Unit (BMU) for control and telecom and telemetry function. It also incorporates new features of bi-annual rotation and Image and Mirror motion compensations for improved performance of the meteorological payloads.

<span class="mw-page-title-main">INSAT-4A</span> Communications satellite

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).
