Sentinel 6 launched by NASA’s ESA
Why in Information?
Earlier in November, Copernicus Sentinel-6 Michael Freilich satellite was launched. It took off from the Vandenberg Air Drive base in California and a SpaceX Falcon 9 rocket was used for the method.
Significance and use
The mission was launched and directed to measure the peak of the ocean, which in flip would assist in understanding how the Earth’s local weather change is going on. The mission can also be known as the Jason Continuity of Service Jason CS mission. It could assist in understanding how the ocean shops and distributes warmth, water, and carbon within the local weather of Earth.
About mission-
It’s a joint collaboration of the European Area Company, ESA, NASA, EUMETSAT, Nationwide Oceanic and Atmospheric Administration within the USA, NOAA, and the European Union. It additionally has contributions from France’s Nationwide Centre for Area Research, CNES.
How it could work?
This satellite tv for pc could be sending pulses to the Earth’s floor to measure how a lot time they take to return to it, which in flip would assist in measuring the ocean depth. It should additionally measure water vapor, ocean currents, warmth waves, and so on alongside this path and discover its place utilizing GPS and ground-based lasers.
Missions in historical past
Wanting down the historical past different satellites that are a joint mission of NASA and CNES, launched had been in 1992 to trace modifications within the oceans on a worldwide scale embody the TOPEX/Poseidon, Jason-1, and OSTN/Jason-2, and so on.

IRNSS acknowledged as a element of WWRNS
Why in Information?
The Maritime Security Committee, MSC, of the Worldwide Maritime Organisation, IMO has given recognition to the Indian Regional Navigation Satellite tv for pc System, IRNSS as a element of the World Large Radio Navigation System, WWRNS throughout its 102nd session. It was carried out just about.
Significance-
- India is now the fourth nation on the planet to have its personal regional navigation satellite tv for pc system being acknowledged by the IMO to be part of the World Large Radio Navigation System, WWRNS.
- The opposite three international locations which have their navigation programs acknowledged by the IMO are the USA, Russia, and China.
- The navigation system might be used as a alternative to GPS within the Indian Ocean waters as much as 1500 km from our boundaries.
What’s IMO?
The IMO is the United Nations specialised company that’s liable for the security and safety of transport and the prevention of marine and atmospheric air pollution attributable to ships.
IRNSS – A historic background
- IRNSS is India’s regional navigation satellite tv for pc system developed by the Indian Area Analysis Group, ISRO.
- Its goal is to supply place, navigation, and time companies throughout India and its neighboring international locations.
