Context: The Indian Space Research Organisation (ISRO) has released images of Earth captured by the EOS-06 satellite. The space agency said that the images are a mosaic generated by the ISRO’s National Remote Sensing Centre (NRSC). ”NRSC/ISRO has generated a global False Colour Composite (FCC) mosaic from the images captured by the Ocean Colour Monitor (OCM) payload on board EOS-06.
- The main space agency of the nation is the Indian Space Research Organisation, which has its headquarters in Bangalore.
- The Chairman of ISRO also acts as the administrator of the Department of Space (DOS), which is overseen by the Prime Minister of India directly.
- India’s primary agency for tasks relating to space-based applications, space exploration, and related technology development is ISRO.
- Just six government space agencies worldwide have comprehensive launch capabilities, cryogenic engines, the ability to launch interplanetary missions, and the capacity to manage vast networks of artificial spacecraft.
Earth Observation Satellites
- The spacecraft with remote sensing capabilities are earth observation satellites. Information on the planet’s physical, chemical, and biological processes is gathered via earth observation.
- The use of several earth observation satellites in sun-synchronous orbit is common.
- They are made to observe the planet from orbit for both military and non-military purposes, such as meteorology and mapping.
- The Oceansat EOS-06 third-generation satellite and eight Nano-satellites were launched by ISRO on November 26 on the PSLV-C54.
- With a larger payload capacity and four payloads—OCM, Sea Surface Temperature Monitor, Ku-Band Scatterometer, and ARGOS—EOS-06 continues Oceansat-2’s activities.
- For use in oceanography, climatology, and meteorology, the EOS-06 is intended to gather data on ocean colour, sea surface temperature, and wind vector.
- In addition, the satellite offers value-added services like potential fishing areas based on data from land-based geophysical systems, SST, wind speed, and chlorophyll.
- With the OCM’s ability to detect the Earth in 13 distinct wavelengths, the images provide information on the global plant cover on land and ocean biota.
- A kind of nanosatellite known as Oceansat-3 was launched by ISRO as part of a larger collection of spacecraft used for oceanographic and atmospheric research.
Ocean Color Monitor
- The sophisticated 13-channel OCM, which has a 1400 km swath and a spatial resolution of 360 m, will continuously monitor the dayside of the globe and provide vital information on the distribution of ocean algae, the building blocks of the marine ecosystem’s food chain.
- With a high signal-to-noise ratio, the OCM-3 is expected to improve accuracy in daily phytoplankton monitoring, which will be useful for a variety of operational and research purposes, such as managing fisheries resources, absorbing ocean carbon, warning of dangerous algal blooms, and analysing climate change.
