ಭಾರತದ ಸಂವಹನ ಉಪಗ್ರಹ ಸಿಎಂಎಸ್-೦೧ ಉಡಾವಣೆ

 ಭಾರತದ ಸಂವಹನ ಉಪಗ್ರಹ ಸಿಎಂಎಸ್-೦೧ ಉಡಾವಣೆ

ನವದೆಹಲಿ: ಭಾರತೀಯ ಬಾಹ್ಯಾಕಾಶ ಸಂಶೋಧನಾ ಸಂಸ್ಥೆಯು (ಇಸ್ರೋ) 2020 ಡಿಸೆಂಬರ್ 17ರ ಗುರುವಾರ ಮಧ್ಯಾಹ್ನ ಸಿಎಂಎಸ್-೦೧ ಹೆಸರಿನ ದೇಶದ ೪೨ ನೇ ಸಂವಹನ ಉಪಗ್ರಹವನ್ನು ಉಡಾವಣೆ ಮಾಡಿತು.

ಬಾಧಿಸುತ್ತಿರುವ ಕೊರೋನವೈರಸ್ (ಕೋವಿಡ್ -೧೯) ಸಾಂಕ್ರಾಮಿಕದ ಮಧ್ಯೆ ಬಾಹ್ಯಾಕಾಶ ಇಸ್ರೋ ಉಡಾವಣೆ ಮಾಡಿದ ಎರಡನೇ ಉಪಗ್ರಹ ಇದಾಗಿದೆ.

ಆವರ್ತನ ವರ್ಣಪಟಲದ ವಿಸ್ತೃತ-ಸಿ ಬ್ಯಾಂಡ್ನಲ್ಲಿ ಸೇವೆಗಳನ್ನು ಒದಗಿಸಲು ಸಾಧ್ಯವಾಗುವಂತೆ ಸಿಎಂಎಸ್ -೦೧ ರೂಪಿಸಲಾಗಿದೆ, ಭಾgತದ ಮುಖ್ಯ ಭೂಪ್ರದೇಶ, ಅಂಡಮಾನ್-ನಿಕೋಬಾರ್ ಮತ್ತು ಲಕ್ಷದ್ವೀಪ ದ್ವೀಪಗಳು ಉಪಗ್ರಹದ ವ್ಯಾಪ್ತಿಗೆ ಸೇರಿವೆ ಎಂದು ಸುದ್ದಿ ಸಂಸ್ಥೆ ವರದಿ ತಿಳಿಸಿದೆ.

ಜಿಎಸ್ಎಟಿ ಮತ್ತು ಇನ್ಸಾಟ್ ಸರಣಿಯ ನಂತರ ಭಾರತವು ಉಡಾಯಿಸಿರುವ ಹೊಸ ಸಂವಹನ ಉಪಗ್ರಹಗಳಲ್ಲಿ ಇದು ಮೊದಲನೆಯದಾಗಿದೆ.

"ಸಂವಹನ ಉಪಗ್ರಹ ಸಿಎಮ್ಎಸ್ -೦೧ ಪೋಲಾರ್ ಸ್ಯಾಟಲೈಟ್ ಲಾಂಚ್ ವೆಹಿಕಲ್ನ್ನು (ಪಿಎಸ್ಎಲ್ವಿ-ಸಿ ೫೦) ಗುರುವಾರ ಶ್ರೀಹರಿಕೋಟಾದ ಸತೀಶ ಧವನ್ ಬಾಹ್ಯಾಕಾಶ ಕೇಂದ್ರದ (ಎಸ್ಡಿಎಸ್ಸಿ) ಶಾರ್ನಿಂದ ಉಡಾಯಿಸಲು ನಿಗದಿಪಡಿಸಲಾಗಿದೆ" ಎಂದು ಇಸ್ರೋ ಇದಕ್ಕೆ ಮುನ್ನ ಹೇಳಿತ್ತು.

ಇದು ಎಸ್ಡಿಎಸ್ಸಿ ಶಾರ್ನಿಂದ ೭೭ ನೇ ಉಡಾವಣಾ ವಾಹನ ಮಿಷನ್ ಆಗಿದ್ದು, ಹೊಸ ಉಪಗ್ರಹವು ೨೦೧೧ ರಲ್ಲಿ ಉಡಾವಣೆಯಾದ ಕಕ್ಷೆಯಲ್ಲಿ ಜಿಎಸ್ಎಟಿ -೧೨ ಅನ್ನು ಬದಲಾಯಿಸಲಿದೆ.

ನವೆಂಬರ್ ರಂದು ಇಸ್ರೋ ಶನಿವಾರ ಪೋಲಾರ್ ಸ್ಯಾಟಲೈಟ್ ಲಾಂಚ್ ವೆಹಿಕಲ್ (ಪಿಎಸ್ಎಲ್ವಿ) ೫೧ ನೇ ಕಾರ್ಯಾಚರಣೆಯನ್ನು ಪ್ರಾರಂಭಿಸಿತ್ತು.

ವಾಹಕ ವಾಹನ ಪಿಎಸ್ಎಲ್ವಿ ಸಿ ೪೯ ಒಟ್ಟು ೧೦ ಉಪಗ್ರಹಗಳನ್ನು ಇಒಎಸ್ -೦೧ ರೊಂದಿಗೆ  ಕಕ್ಷೆಗೆ ತಲುಪಿಸಿದೆ. ಭೂಮಿಯ ವೀಕ್ಷಣಾ ಉಪಗ್ರಹವಾದ ಇಒಎಸ್ -೦೧ ಕೃಷಿ, ಅರಣ್ಯ ಮತ್ತು ವಿಪತ್ತು ನಿರ್ವಹಣಾ ಬೆಂಬಲವನ್ನು ಒದಗಿಸುವ ಉದ್ದೇಶವನ್ನು ಹೊಂದಿದೆ.

Nasa blasts off space laser satellite that will track loss of ice cover on Earth


Nasa blasts off space laser satellite that will
track loss of ice cover on Earth

Los Angeles:  Nasa’s most advanced space laser satellite blasted off Saturday, 15th September 2018, on a mission to track ice loss around the world and improve forecasts of sea level rise as the climate warms.


Cloaked in pre-dawn darkness, the $1 billion, half-ton ICESat-2 launched aboard a Delta II rocket from Vandenberg Air Force base in California at 6:02 am (1302 GMT).
“Three, two one, liftoff!” said a launch commentator on Nasa television.


“Lifting ICESat-2 on a quest to explore the polar ice sheets of our constantly changing home planet.”


The launch marks the first time in nearly a decade that Nasa has had a tool in orbit to measure ice sheet surface elevation across the globe.


The preceding mission, ICESat, launched in 2003 and ended in 2009.


The first ICESat revealed that sea ice was thinning, and ice cover was disappearing from coastal areas in Greenland and Antarctica.


In the intervening nine years, an aircraft mission called Operation IceBridge, has flown over the Arctic and Antarctic, taking height measurements of the changing ice.


But a view from space -- especially with the latest technology -- should be far more precise.


The new laser will fire 10,000 times in one second, compared to the original ICESat which fired 40 times a second.


Measurements will be taken every 2.3 feet (0.7 meters) along the satellite’s path.


“The mission will gather enough data to estimate the annual elevation change in the Greenland and Antarctic ice sheets even if it’s as slight as four millimeters - the width of a No. 2 pencil,” Nasa said in a statement.


Importantly, the laser will measure the slope and height of the ice, not just the area it covers.


“One of the things that we are trying to do is, one, characterize the change that is taking place within the ice, and this is going to greatly improve our understanding of that, especially over areas where we don’t know how well it is changing right now,” said Tom Wagner, cryosphere program scientist at Nasa, mentioning the deep interior of Antarctica as one such area of mystery.


The mission is meant to last three years but has enough fuel to continue for 10, if mission managers decide to extend its life.

'Desi' GPS system may soon become reality

'Desi' GPS system may soon become reality

ISRO, CSIR-NPL join hands
New Delhi: An indigenous Now 'desi' GPS may soon become reality as ISRO, CSIR-NPL join hands for services.

India's premiere space research organisation ISRO and the CSIR-NPL plan to launch a time and frequency traceability service, a media report said on Thursday, 03rd August 2017.
The Indian Space Research Organisation and the CSIR-National Physical Laboratory were expected to sign an MoU on Friday for this indegenous system named as Navigation with Indian Constellation (NavIC).
As per the plan, the desi GPS will formally get synchronised with the Indian Standard Time (IST) maintained by Delhi-based NPL - India's timekeeper, the report said.
Time synchronisation is key for a variety of purposes such as financial transactions, stock handling, digital archiving, time stamping, national security and prevention of cyber crimes, it said, adding, the move would help in making the indegenous system operational in the market for commercial purposes.
"We can't depend forever on the US-based National Institute of Standards and Technology (NIST). After signing the MoU, the space clocks will be syncronized to that of the Primary National Atomic Clocks at National Physical Laboratory and therefore will have independence," TOI quoted NPL director Dinesh Aswal as saying.
"Though millisecond or microsecond accuracy is sufficient for day-to-day activities, the ISRO needs accuracy up to nanoseconds level for navigation, surveillance and other national missions," he added.
Citing MoS for space & atomic energy Jitendra Singh, the report however said the NavIC may take several years before it becomes operational in the market.
A constellation of seven satellites will comprise the NavIC, which will provide Position, Navigation and Timing (PNT) services in India and the adjoining region up to 1,500 km, the report said.
The NavIC will provide two types of services - Standard Positioning Service (SPS) and Restricted Service (RS), it added.

Selfie Video of ISRO’s PSLV Sattellite record!

Selfie Video of ISRO’s PSLV Sattellite record!
Sriharikota : Scripting history, India on Wednesday, 15th February 2017, successfully launched a record 104 satellites--all but three of them foreign--from here and put them into orbit in a single mission onboard its most dependable Polar rocket.

Recording its 38th consecutive success, ISRO's workhorse Polar Satellite Launch Vehicle (PSLV) injected India's weather observation Cartosat-2 Series satellite and 103 nano satellites into precise orbit in a gap of 30 minutes after a textbook lift-off from this spaceport, about 100 km from Chennai.

The complete process was recorded in the selfie video of PSLV. Watch the wonderful video here by clicking the image below.
