Indian National Academy Of Engineering
The Indian National Academy of Engineering (INAE) was founded in 1987. It consists of India's engineers, engineer-scientists and technologists covering the entire spectrum of engineering disciplines. The academy is registered under the Societies Registration Act 1860 and is an autonomous institution supported partly through grant-in-aid by Department of Science & Technology, Government of India. As the only engineering Academy of the country, INAE represents India at the International Council of Academies of Engineering and Technological Sciences (CAETS). INAE functions as an apex body and promotes the practice of engineering and technology and the related sciences for their application to solving problems of national importance. The academy also provides a forum for futuristic planning for the country's development, requiring engineering and technological inputs and brings together specialists from such fields as may be necessary for comprehensive solutions to the needs of ...

INSAT-2E
INSAT-2E is an Indian geostationary communications and weather satellite which is operated by the Indian National Satellite System. It is positioned in geostationary orbit at a longitude of 83° East, from where it is used to provide communications services to Asia and Australia. It also carries two meteorological instruments; the Very High Resolution Radiometer, and a CCD camera capable of returning images with a resolution of one kilometre. The communications payload aboard INSAT-2E consists of seventeen G/H band (IEEE C band) transponders. At launch the satellite had a mass of , with an expected operational lifespan of 12 years. Some of its transponders are leased to Intelsat, who operate them under the designation ''Intelsat APR-2''. INSAT-2E was launched by Arianespace, using an Ariane 42P carrier rocket flying from ELA-2 at the Guiana Space Centre. The launch occurred at 22:03 UTC on 2 April 1999. Following launch, it raised itself into geostationary orbit using liquid-fue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Remote Sensing
India's remote sensing program was developed with the idea of applying space technologies for the benefit of humankind 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 o ...

Spacecraft Attitude Control
Spacecraft attitude control is the process of controlling the orientation of a spacecraft (vehicle or satellite) with respect to an inertial frame of reference or another entity such as the celestial sphere, certain fields, and nearby objects, etc. Controlling vehicle attitude requires actuators to apply the torques needed to orient the vehicle to a desired attitude, and algorithms to command the actuators based on the current attitude and specification of a desired attitude. Before and during attitude control can be performed, spacecraft attitude determination must be performed, which requires sensors for absolute or relative measurement. The broader integrated field that studies the combination of sensors, actuators and algorithms is called ''guidance, navigation and control'', which also involves non-attitude concepts, such as position determination and navigation. Motivation A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

INSAT satellites provide transponders in various bands to serve the television and communication needs of India. Some of the satellites also have the Advanced Very High Resolution Radiometer, Very High Resolution Radiometer (VHRR), Charge-coupled device, CCD cameras for meteorology, meteorological imaging. The satellites also incorporate transponder(s) for receivin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ariane Passenger Payload Experiment
The Ariane Passenger PayLoad Experiment (APPLE), was an experimental communication satellite with a C-Band transponder launched by the Indian Space Research Organisation on June 19, 1981, by Ariane, a launch vehicle of the European Space Agency (ESA) from Centre Spatial Guyanais near Kourou in French Guiana. APPLE was India's first three-axis stabilised experimental Geostationary communication satellite. On July 16, 1981, the satellite was positioned at 102° E longitude. The 672 kg satellite served as testbed of the Indian telecommunications space relay infrastructure despite the failure of one solar panel to deploy. Solid-propellant based Apogee Boost Motor to circularize APPLE's orbit was derived from SLV-3 fourth stage. It was used in several communication experiments including relay of TV programmes and radio networking. It was a cylindrical spacecraft measuring 1.2 m in diameter and 1.2 m high. Its payload consisted of two 6/4 GHz transponders connected to a 0. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
