  • Indian Remote Sensing Satellites (IRS)
    Topic: Indian Remote Sensing Satellites (IRS) Course: Remote Sensing and GIS (CC-11) M.A. Geography (Sem.-3) By Dr. Md. Nazim Professor, Department of Geography Patna College, Patna University Lecture-5 Concept: India's remote sensing program was developed with the idea of applying space technologies for the benefit of human kind and the development of the country. The program involved the development of three principal capabilities. The first was to design, build and launch satellites to a sun synchronous orbit. The second was to establish and operate ground stations for spacecraft control, data transfer along with data processing and archival. The third was to use the data obtained for various applications on the ground. India demonstrated the ability of remote sensing for societal application by detecting coconut root-wilt disease from a helicopter mounted multispectral camera in 1970. This was followed by flying two experimental satellites, Bhaskara-1 in 1979 and Bhaskara-2 in 1981. These satellites carried optical and microwave payloads. India's remote sensing programme under the Indian Space Research Organization (ISRO) started off in 1988 with the IRS-1A, the first of the series of indigenous state-of-art operating remote sensing satellites, which was successfully launched into a polar sun-synchronous orbit on March 17, 1988 from the Soviet Cosmodrome at Baikonur. It has sensors like LISS-I which had a spatial resolution of 72.5 meters with a swath of 148 km on ground. LISS-II had two separate imaging sensors, LISS-II A and LISS-II B, with spatial resolution of 36.25 meters each and mounted on the spacecraft in such a way to provide a composite swath of 146.98 km on ground.

  • The Geostrategic Implications of India's Space Program
    THE GEOSTRATEGIC IMPLICATIONS OF INDIA’S SPACE PROGRAM Dinshaw Mistry In August 1999, India announced a draft nuclear doc- trine that declared that its nuclear forces would be based on “a triad of air- craft, mobile land-based missiles, and sea-based assets,” and that “space- based and other assets shall be created to provide early warning, communica- tions, [and] damage/detonation assessment” for this force.1 The draft doc- trine was not official government policy; it primarily represented the thinking of technical and political elites who influence Delhi’s nuclear decision mak- ing to varying degrees. Nevertheless, although the government of India ulti- mately distanced itself from the document, Delhi has still been pursuing many of the doctrine’s technical parameters. And while it may take India several years to build and deploy a robust nuclear arsenal, many of the tech- nologies required for such a force are already becoming available through the country’s space program. India’s space program undertakes two major activities–it builds satellites used for remote-sensing, meteorology, and communications and constructs the rockets to launch its satellites. These space assets have found both civil- ian and military applications. In the 1970s and 1980s, India’s first satellite launch vehicle, the SLV-3, was powerful enough only to launch a light payload (typically, a scientific satellite) to 300–450-km altitude low earth orbit (LEO). Such light-weight low-orbit satellites did not have significant military or commercial capabilities. However, the SLV-3 could still be used as an intermediate range ballistic missile. Dinshaw Mistry is Fellow at the Belfer Center for Science and Interna- tional Affairs, Kennedy School of Government, Harvard University, Cambridge, Mass.
