Bhaskara-I and -II were two satellites built by the Indian Space Research Organisation that formed India's first low-Earth orbit Earth observation satellite. They collected data on oceanography and hydrology. The satellites are named after the ancient Indian mathematicians Bhāskara I and Bhāskara II. [1]
Earth observation satellite. First operational remote sensing satellite. 18960 – 902.3 km ... India's first pico-satellite (weighing less than 1 kg). It was ...
NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather ...
Following the successful demonstration flights of Bhaskara-1 and Bhaskara-2 satellites launched in 1979 and 1981, respectively, India began to develop the indigenous Indian Remote Sensing (IRS) satellite program to support the national economy in the areas of agriculture, water resources, forestry and ecology, geology, water sheds, marine fisheries and coastal management.
An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation (EO) from orbit, including spy satellites and similar ones intended for non-military uses such as environmental monitoring, meteorology, cartography and others.
RISAT (Radar Imaging Satellite) is a series of Indian radar imaging reconnaissance satellites built by the Indian Space Research Organization (ISRO). They provide all-weather surveillance using synthetic aperture radars (SAR). The RISAT series are the first all-weather Earth observation satellites from ISRO.
Aryabhata was India's first satellite, [2] named after the astronomer. [3] It was launched on 19 April 1975 [2] from Kapustin Yar, a Soviet rocket launch and development site in Astrakhan Oblast using a Kosmos-3M launch vehicle.
The timeline of first Earth observation satellites shows, in chronological order, those successful Earth observation satellites, that is, Earth satellites with a program of Earth science. Sputnik 1, while the first satellite ever launched, did not conduct Earth science. Explorer 1 was the first satellite to make an Earth science discovery when ...
