Topic: Insat


  
  Indian Space Program
Between 1982 and 1990 four U.S.-built INSAT 1 satellites were launched to support Indian domestic communications and Earth observation requirements as a joint venture among the Indian Department of Space, the Department of Telecommunications, the Meteorological Department, All-India Radio, and All India Doorarshan Television.
INSAT 1 D (June, 1990) was operational at 83 degrees E. The INSAT 2 program was underway in 1983 to develop an indigenous multi-purpose GEO spacecraft that relied heavily on the previous Ford Aerospace design.
INSAT 2B was launched 22 July 1993 by an Ariane rocket and positioned at 93.5 degrees E. In March, 1994, India selected Arianespace to launch INSATs 2C and 2D in 1995 and 1996, respectively.

 Insat
Insat (Indian National Satellite System) was a multipurpose satellite system for telecommunications, broadcasting, meteorology and search and rescue services.
Commissioned in 1983, Insat was the largest domestic communication system in the Asia-Pacific Region, and was a joint venture of the Indian Department of Space (DOS), Department of Telecommunications, India Meteorological Department, All India Radio and Doordarshan.
In geostationary orbit the satellite was to be co-located with Kalpana-1 and Insat-3C satellites at 74 deg East longitude.

 The promise of INSAT-2E
Among the satellites of the INSAT system, INSAT-1D, launched in 1990, is well past its nominal life and is already in an inclined orbit, the inclination amounting to more than 1°.
The multi-purpose satellite is perhaps the most advanced in the INSAT series so far in terms of technologies used in the hardware and in the payloads.
INSAT is the only satellite system which carries this frequency band after it was released for VSAT use by the International Telecommunication Union (ITU) and it has been adopted for VSAT communications.

About 21 minutes later the Insat 3C spacecraft, developed and built by the Indian Space Research Organization, was successfully deployed from the rocket's third stage, having arrived in a highly elliptical geosynchronous transfer orbit with a low point of 570 km, a high point of 35,920 km and inclination of 4 degrees.
Insat 3C's communications payload of 30 C-band transponders, two S-band transponders and a single transponder for mobile communications services will continue the services of the aging Insat 2C and Insat 2DT, which are nearing their end of their service lives, ISRO said.
Insat 3C is the second satellite of the Insat 3 series of spacecraft to be launched.

 Private Firms Rushing To Book Insat-3A Capacity   (Site not responding. Last check: 2007-10-11)
The rush reflects the Insat system’s attractive leasing rates and a shortage of Insat capacity relative to demand.
In addition to giving government users priority on Insat, India’s satellite telecommunications policy bars all domestic customers from using foreign satellites if the national system is available to provide the same service.
For television broadcasters, the Insat system is attractive because its transponder lease rates typically are lower than those for foreign-owned transponders, the ISRO source said.

INSAT 2B satellite, which supports the country's telecommunications and broadcast sectors was shut down after a technical hitch, the state-run space research agency said on Saturday.
Krishnamurthy explained that the loss of earth-lock meant that the direction of the satellite, which is fixed to constantly face a specific side of the earth, had changed.
The satellite is one of seven in the INSAT series that are the mainstay of India's telecommunications, broadcasting and meteorological functions.

 The Hindu : INSAT 3E will take tally to 128 transponders
With the launch of INSAT 3E, the Indian Space Research Organisation's communications satellite, on September 28, the country's tally of communication transponders in space will go up to 128, G. Madhavan Nair, Secretary, Department of Space and Chairman ISRO, said here today.
INSAT 3E, the penultimate spacecraft in the INSAT 3 series, will be launched aboard the French Ariane 5 rocket from the spaceport of Kourou, French Guyana.
A successful launch of INSAT 3E — after successive delays, the last due to a component alert — is important not in the least because its transponders will take on the traffic now being handled by 23 transponders on INSAT 2DT which is nearing the end of its life.

They said the orbit-raising operations started on January 25th from the INSAT Master Control Facility (MCF) at Hassan, some 180 km from Bangalore, in Karnataka, which took control of the spacecraft after it was shot into space.
The manoeuvres, the sources said, would finally put the satellite in a geostationary orbit, stationary with relation to a point on the earth, at 74º East longitude with an altitude of 36,000 km and inclination of 4º to the equator.

 Introduction
INSAT is one of the largest domestic communication satellite systems in the Asia Pacific Region with five satellites, INSAT-2C, INSAT-2DT, INSAT-2E, INSAT-3B and INSAT-3C in operation.
To partly augment the capacity of the INSAT system consequent to the loss of INSAT-2D (in October, 1997), an in-orbit satellite, ARABSAT-1C was procured from ARABSAT Organisation, a regional inter-governmental satellite consortium of Arab States.
A minor shortfall of 0.6 percent in the velocity of injection of the satellite resulted in a reduction of orbital apogee of the satellite while the perigee and inclination were close to targeted values.

Satellite arrays include IRS (Indian Remote Sensing) satellite series, INSAT (Indian National Satellite) series (in Geo-Stationary orbit), GSAT series (launched using GSLV) and METSAT 1 (launched by PSLV).
The Insat series of satellites include the 1 (A, B,C, D), 2 (A, B,C, D/DT) and 3 (A, B,C, D,E) series.
Most of these satellites were launched by the Arianespace for ISRO, the latest being INSAT 3E.

 On the launch pad
The unexpected loss of six XC transponders aboard INSAT-2D could not be compensated either by the acquisition of the in-orbit satellite ARABSAT-1C (redesignated as INSAT-2DT and moved over to the Indian slot in the geosynchronous orbit at 55°E) or by the launch of INSAT-2E (in April 1999) as neither satellite had XC transponders.
However, the failure of the VHRR scan assembly aboard INSAT-2E, which led to the infamous fiasco in the prediction of cyclone landfall by the India Meteorological Department (IMD) during the Orissa super cyclone, resulted in a reshuffle of the INSAT-3 series.
The repeated failure of the meteorological payload aboard INSAT - earlier there were problems in respect of receiving IR data from INSAT-2A and INSAT-2B - required a complete relook at the met payload, the VHRR in particular.
