Essay On Space Science And Research

It had eleven satellites in operation-INSAT- 2E, INSAT-3A, INSAT-3B, INSAT-3C, INSAT-3E, KALPANA-1, GSAT-2, EDUSAT (GSAT-3), INSAT- 4A, INSAT-4B and INSAT-4CR by end 2007.

It has 17 transponders, of which 12 are in the normal C- band and five in the lower extended C-band, a VHRR similar to that of INSAT-2A and INSAT- 2B but with an additional water vapour channel, and a Charge Coupled Device (CCD) camera operating in visible, near infrared, and shortwave infrared bands with 1 km resolution.

The VHRR and CCD on INSAT-2E are expected to considerably improve weather prediction and modelling.

While implementing the above objectives, DOS is to provide required satellite transponders and facilities to meet the communication, television broadcasting and security requirement of our country; adequate earth observation capability in multiple spectral, spatial and temporal resolutions; launch services to meet national requirements and commercial needs; and its products and services in a prompt and efficient manner to all the users/clients.

The Department of Space has the primary responsibility of promoting development of space science, technology and applications towards achieving self-reliance and assisting in all round development of the nation.

The establishment of space systems and their utilisation are coordinated by national level committees, namely, the INSAT Coordination Committee (ICC), Planning Committee of National Natural Resources Management System (PCNNRMS) and Advisory Committee on Space Sciences (ADCOS).

Five Regional Remote Sensing Service Centres (RRSSC) help in undertaking remote sensing application projects relevant to the region.The International Telecommunications Satellite Organisation (INTELSAT))—an international inter-governmental space consortium, created in association with 133 countries—has leased eleven 36 MHz equivalent units of C-band capacity on INSAT-2E.Of the five satellites, INSAT-3A through INSAT- 3E, planned under INSAT-3 series, four satellites— INSAT-3A, INSAT-3B, INSAT-3C and INSAT-3E— have already been launched and are providing satisfactory service.The executive wing of the Commission is the Department of Space (DOS) which operates through the Indian Space Research Organisation (ISRO), Bangalore, National Remote Sensing Agency (NRSA), the Physical Research Laboratory (PRL), Ahmedabad, National Mesosphere- Stratosphere-Troposphere Radar Facility (NMRF), North Eastern-Space Applications Centre (NE-SAC), besides sponsoring research projects in other institutions.The Antrix Corporation, a wholly Government owned company, which was established in 1992, is engaged in commercial marketing of space products and services.For the IMD, INSAT-2B mainly served as an in-orbit back-up for collection and dissemination of meteorological data via the data relay transponder.INSAT-2E, the last of the second generation INSAT series, was launched by the European launch vehicle, Ariane, from the Kourou space station in French Guyana on April 3, 1999.The Indian space programme is geared to the utilisation of space technology for the socio­economic development of the country.The Indian space programme has its genesis in the Indian National Committee for Space Research (INCOSPAR) that was formed under the chairmanship of Dr Vikram Sarabhai by the Department of Atomic Energy in 1962.INSAT-3B, intended for business communi­cation, developmental communication and mobile communication, carries 12 extended C-band transponders, 3 Ku-band channels and mobile satellite service transponders.It is expected to boost VSAT services for banking and financial institutions, stock markets, fast moving consumer goods sector and medium to heavy engineering companies.
