What Are The Names Of The First 5 Satellites Launched By India?
Aryabhata
It was launched by the Soviet Union on 19 April 1975 from Kapustin Yar using a Kosmos-3M launch vehicle. It was built by the Indian Space Research Organisation to gain experience in building and operating a satellite in space. The launch came from an agreement between India and the Soviet Union directed by U.R. Rao and signed in 1972. It allowed the USSR to use India ports for tracking ships and launching vessels in return for launching India satellites.
On 19 April 1975 the satellite’s 96.46-minute orbit had an apogee of 611 kmand a perigee of 568 km, at an inclination of 50.6 degrees. It was built to conduct experiments in X-ray astronomy, aeronomics, and solar physics. The spacecraft was a 26-sided polyhedron 1.4 m in diameter. All faces (except the top and bottom) were covered with solar cells. A power failure halted experiments after four days and 60 orbits with all signals from the spacecraft lost after five days of operation. According the Soviet media reports, the satellite continued to function and transmit information for some time.
The satellite reentered the Earth’s atmosphere on 11 February 1992. 1984 USSR stamp featuring Bhaskara-I, Bhaskara-II and Aryabhata satellites. The satellite’s image appeared on the reverse of Indian 2 rupee banknotes between 1976 and 1997 (Pick catalog and one rupee note number: P-79a-m). Aryabhata was named for the 5th century astronomer and mathematician from India by the same name.
Bhaskara-I
The Bhaskara-I and II Satellites were two satellites built by the Indian Space Research Organisation that formed India’s first low orbit Earth Observation Satellite. They collected data on telemetry, oceanography and hydrology. Bhaskara-I, weighing 444 kg at launch, was launched on 7 June 1979 from Kapustin Yar aboard the Intercosmos launch vehicle. It was placed in an orbital Perigee and Apogee of 394 km and 399 km at an inclination of 50.7°.
The satellite consisted of Two television cameras operating in visible (600 nanometre) and near-infrared (800 nanometre) and collected data related to hydrology, forestry and geology. Satellite microwave radiometer operating at 19 and 22 GHz for study of ocean-state, water vapour, liquid water content in the atmosphere, etc.
Rohini Technology Payload
Rohini is the name given to a series of satellites launched by the Indian Space Research Organisation. The Rohini series consisted of four satellites, all of which were launched by the Indian space research organisation Satellite Launch Vehicle and three of which made it successfully to orbit. The series were mostly experimental satellites. Rohini Technology Payload. It was a 35 kg experimental spin stabilised satellite that used 3W of power and was launched on 1979-08-10 from SDSC. The satellite contained instruments to monitor the launch vehicle. It did not achieve its intended orbit as the carrier rocket SLV was only ‘partially successful’.
RS-1- It was also a 35 kg experimental spin stabilised satellite that used 16W of power and was successfully launched on 1980-07-18 from SDSC into an orbit of 305 x 919 km with an inclination of 44.7°. The satellite provided data on the 4th stage of SLV. The satellite had an orbital life of 20 months.
RS-D- It was a 38 kg experimental spin stabilised satellite that used 16 W of power and was launched on 1981-05-31 The launch of the SLV was a partial success as the satellite did not reach the intended height and thus it only stayed in orbit for 9 days. It achieved an orbit of 186 x 418 km with an inclination of 46° The satellite carried a solid state camera for remote sensing applications that performed to specifications.
RS-D2- It was a 41.5 kg experimental spin stabilised satellite that used 16 W of power and was launched successfully on 1983-04-17 into an orbit of 371 x 861 km and an inclination of 46°. The satellite was in operation for 17 months and its main payload, a Smart sensor camera took over 2500 pictures. The camera had the capability to take pictures both in Visible and infrared bands. It reentered the atmosphere on 19 April 1990.
