first satellite‚ Aryabhatta‚ was built by ISRO and launched by the Soviet Union in 1975. Rohini‚ the first satellite to be placed in orbit by an Indian-made launch vehicle‚ SLV-3‚ was launched in 1980. ISRO subsequently developed two other rockets: the Polar Satellite Launch Vehicle (PSLV) for putting satellites into polar orbits and the Geosynchronous Satellite Launch Vehicle (GSLV) for placing satellites into geostationary orbits. These rockets have launched numerous communications satellites‚ earth

assumptions to become part of arms control and arms race discussions. Its estimated that about 75% of the total number of satellites in the earth’s orbit are mainly being used to carry out military activities like early warning‚ navigation‚ communication and surveillance. The great importance of satellites to the military has as a result stirred military planners to come up with anti-satellite systems. Additionally‚ there have been extensive studies in different defense departments regarding the feasibility

launching of a satellite in 1957. The satellites name was Sputnik. All that could be heard from the artificial satellite was just a series of rhythmic “beeps” on October 4‚ 1957. Those short beeps came from the first satellite to be launched into space as it passed overhead. Sputnik was a small round artificial moon that became a major turning point in technology and history in years to come. It was the first satellite to be successfully launched‚ named Sputnik after the Russian word for "satellite‚" was

Science has done great service to mankind. Science has ensured life to be safer‚ surer and much more comfortable than ever before. Science has helped man to make computers‚ artificial satellites and robots. Science has given the Americans a defense umbrella in space and it has given the Russians a permanent space station. Russia‚ it is believed‚ will have an industrial city in space before 2050 A.D. This would be the height of achievement in the field of science and technology. Science has

(2014 - 2019) On 11th March 2014 The Nano and Microsatellite market report constitutes of revenues from hardware‚ software and services required for the development and launch of such satellites. Overall market size is found by adding up the market size for two segments of satellites; namely 1kg to 10kgs (Nano satellites) and 11kgs to 100kgs (Microsatellites). Though above two markets can exist independently‚ but the playing fields are the same. For example‚ there are applications in communication
