- Abstract
Traditionally, satellites have been used primarily for the fixed and broadcast services to connect far-flung corners of the world. Latest technology-developments and the reduction of all types of information and communications to a digital format, however, have opened several unexplored avenues for satellite communication. Trends in satellite communications reflect a shift towards more broadband services. Satcom applications now include direct to the home (DTH), direct broadcast satellite (DBS), mobile telephony, and Internet access as the primary services. This change is possible as a result of the insertion of new technology onto satellites; namely increased power, phased array antennas, large diameter antennas, multi-spot beam antennas, and on-board processing and switching. These changes allow satellites to be a cost effective competitor to cable TV, cellular telephony, and other terrestrial technologies. With its primary emphasis on large scale application of space technology on an end to end basis towards national development, the Indian Space Programme has distinguished itself as one of the most cost-effective and development oriented space programs in the world. The Indian Space programme has evolved over a period of four decades to reach its present level of maturity. The indigenously developed INSAT and GSAT systems have brought a revolution in the communication field in the country and have been providing some unique services. The new ongoing application programmes such as tele-education, telemedicine, disaster warning, search and rescue, village resource centres etc. are indeed fulfilling the objectives of ISRO. Future Indian satellite systems will offer an array of advanced information services. The trend is toward high-speed Internet access and broadband multimedia and IP-based services. Services may range from email and voice to broadband multicasting and interactive video. This article gives an overview of satellite communications systems, technologies and applications evolved under Indian Space Programme over a period of four decades and the future roadmap of the same.
