Apple the first communication satellite of isro was launched from

On July 22nd 1981, India’s first geo-stationary satellite APPLE started functioning. The Ariane Passenger PayLoad Experiment (APPLE), an experimental communication satellite was launched by the Indian Space Research Organisation (ISRO) on July 19th 1981, which began functioning on July 22nd of the same year. APPLE was an experimental communications satellite with a C-Band transponder. This satellite was launched by Ariane, a launch vehicle of the European Space Agency in French Guiana. The successful launch of APPLE was a major milestone for India’s space program. After having successfully placed the APPLE spacecraft in the three axis stabilized mode in the geostationary orbit, India joined the league of nations who had developed their own three axis stabilized stationary communications satellite. APPLE had a launch weight of 673 kgs and a cylindrical structure of 1200 mm diameter and a height of 1985 mm. On July 19th 1981, the satellite was placed at 102 degrees east longitude and proved to be an important landmark in Indian space research. APPLE was designed and developed at the ISRO Satellite Centre in Bangalore. The centre was also responsible for the management and development of the spacecraft structure, TTC, power, thermal, control and sensor system, testing, mission planning and launch. After being tested at ISRO, APPLE was sent to Tolouse in France so that compatibility tests could be carried out with METEOSAT and CAT satellites, which would be part of the payload...

Space research activities were initiated in India during the early 1960s. In 1962, the Indian National Committee for Space Research (INCOSPAR) was set up under the Department of Atomic Energy, to spearhead space research activities. The then Prime Minister of India, Jawaharlal Nehru, set up INCOSPAR on the urging of Vikram Sarabhai.

Seeing this, Vikram Sarabhai recognised the benefits of space technologies for India. This image is from the early stages of the Indian Space Programme. (Image: ISRO) The Indian space programme had three distinct elements — satellites for communication and remote sensing, the space transportation system, and application programmes. The satellite programme began on April 19, 1975, with the launch of India's first experimental satellite Aryabhatta. Launched using a Soviet launcher, Aryabhatta was placed in low-Earth orbit.

SITE benefitted around 200,000 people, covering 2,400 villages of six states and transmitted development-oriented programmes using the American Technology Satellite (ATS-6).

Apple [ISRO] Apple ( Ariane Passenger Payload Experiment) was an experimental communications satellite with a C-band transponder, launched on 19 June 1981 by an The spacecraft bus was cylindrical with a diameter of 1.2m and a height of 1.2m. The communications payload consisted of two 6/4GHz transponders connected to a 0.9m diameter parabolic antenna. The fourth stage of the For 27 months (until attitude control fuel depletion) the 350kg Apple successfully served as a testbed for the entire Indian telecommunications space relay infrastructure despite the failure of one solar panel to deploy. Apple was used in several communication experiments including relay of TV programmes, and radio networking. It went out of service on 19 Sep 1983.

Key Highlights • Thirty-five years ago, on June 19, 1981, Isro successfully launched its first communication satellite, Ariane Passenger PayLoad Experiment (Apple), on Ariane-1 from Kourou, French Guiana. • Bhaskara and Rohini had been successes before Apple. • But Apple laid the foundation for indigenous development of operational communication satellites. Bengaluru: The Indian Space Research Organisation (Isro) has become one of the first picks for countries looking to launch satellites. The situation was not always like this. Thirty-five years ago, on June 19, 1981, Isro successfully launched its first communication satellite, Ariane Passenger PayLoad Experiment (Apple), on Ariane-1 from Kourou, French Guiana. This was a major milestone in India's space programme as Apple was used for several communication experiments, including relay of television programmes and radio networking. Incidentally, this satellite was transported on a bullock cart, captured for posterity in an unforgettable photograph. It had only been six years since Aryabhatta, Isro's first satellite, and the agency was still in its infancy much like the country's infrastructure. Isro had been trying launch technology through its SLV class of launchers and the Satellite Telecommunication Experiments Project had been launched. Bhaskara and Rohini had been successes before Apple. But Apple laid the foundation for indigenous development of operational communication satellites which grew into a very large cons...

By Indo-Asian News Service: From the days of having a church as control room, the bishop's house as office and a bicycle as ferry and naked eyes to track the smoke plume at Thumba in Kerala and converting a toilet into a satellite data receiving centre in Bengaluru, Indian space odyssey have come a long way to ferrying foreign satellites, launching moon and Mars orbiters, and now planning to land on the Moon. From Bullock cart to Moon. Apple satellite in 1981. The journey which started humble & now after achievements like PSLV, GSLV, Cryo engines, MOM, Moon & now a moon lander. Kudos & Wishes to all the scientists & researchers for making things happen & making Here's a timeline of the epic journey: 1960s-1990s: The period of trials and turbulations 1962: Indian National Committee for Space Research set up by Department of Atomic Energy and work on establishing Thumba Equatorial Rocket Launching Station (TERLS) started in Kerala. 1963: First sounding rocket launched from TERLS November 21, 1963. 1965: Space Science and Technology Centre established in Thumba, Kerala. 1971: Satish Dhawan Space Centre (formerly SHAR Centre) was formed in Sriharikota, Andhra Pradesh. 1972: Department of Space (DOS) established and ISRO brought under DOS.
