Organisational Structure And Important Satellites – ISRO

GENESIS OF ISRO

  • During the early 1960’s when applications using satellites were in experimental stages even in the United States, the space research activities were initiated in our country. With the live transmission of Tokyo Olympic Games across the Pacific by the American Satellite ‘Syncom-3’ demonstrating the power of communication satellites, Dr Vikram Sarabhai, the founding father of Indian space programme, quickly recognized the benefits of space technologies for India. Since its inception, the Indian space programme has been orchestrated well and had three distinct elements such as satellites for communication and remote sensing, the space transportation system and application programmes. These three are the basics of Indian space research organization. And with its these unique features ISRO made its progress.

ISRO CHAIRMAN

  • Mr Alur Seelin Kiran Kumar, appointed as ISRO chairman on January 14, 2015.HE is distinguished APEX scientist and director, space application centre, Ahmedabad.

The Indian Space Research Organisation (ISRO)

  • The Indian Space Research Organisation (ISRO) is the space agency of the Government of India headquartered in the city of Bengaluru. Its vision is to “harness space technology for national development while pursuing space science research and planetary exploration. It was Formed in 1969, superseded the erstwhile Indian National Committee for Space Research (INCOSPAR) established in 1962 by the efforts of independent India’s first Prime Minister, Jawaharlal Nehru, and his close aide and scientist Vikram Sarabhai.

Mission

  • Design and development of launch vehicles satellites and related technologies for providing access to space and for earth observation, communication, navigation, meteorology and space science.
    Indian National Satellite (INSAT) and Indian Remote Sensing Satellite (IRS) programme for meeting telecommunication, television broadcasting and developmental applications and management of natural resources and monitoring of environment using space based imagery.

List of Communication Satellites

  • The Indian National Satellite (INSAT) system is one of the largest domestic communication satellite systems in Asia-Pacific region with nine operational communication satellites placed in Geostationary orbit. Established in 1983 with the commissioning of INSAT-1B, it initiated a major revolution in India’s communications sector and sustained the same later. GSAT-17 joins the constellation of INSAT System consisting 15 operational satellites, namely – INSAT-3A, 3C, 4A, 4B, 4CR and GSAT-6, 7, 8, 9, 10, 12, 14, 15, 16 and 18.
