@sayareakd The image which you have posted and the one which I have posted are the same. Mine is plotted on a flat surface, yours takes into account the curvature of the earth and line of sight from the satellite. But the area that both the images cover is the same, if you notice carefully it covers 1/3 of Africa and 1/3 of Australia in both images.

It seems the area between the inner circle (primary service area) and outer circle is being referred to as extended service area.





If I simply plot a radius of 1500km from the 4 extremities of India we get roughly this much primary coverage area :

which is basically this :

If we add the extended service area we get this :

So it's settled then.

The signal from IRNSS-1A was seen in Germany (with a big antenna though). I'd think the coverage is much larger than what is advertised

Yup, perhaps our military assets will get the full coverage with greater accuracy, and commercial assets will be restricted only to nations with whom we have signed data sharing contracts. Given that EU has their own thing going, they wont allow Indian competition anyway, but it's good to know that we could direct our missiles wherever we want, if the need arises.

10-12000km range Agni 6 will be tested next year.

World's Largest Telescope May Be Set Up In Ladakh

The project was to come up at Mauna Kea in Hawaii, but protests by the locals and indigenous population has stalled the project.​

• The project was to come up at Mauna Kea in Hawaii.
• However, protests by locals and indigenous population stalled it.
• India is a 10% partner in the Thirty Metre Telescope project.

New Delhi: Hawaii's loss may turn out to be Ladakh's gain.

After protests in Hawaii in the US against the proposed Thirty Metre Telescope (TMT) project, the largest to be built, alternative sites are being explored which includes Hanle in Ladakh.

The project, aimed at exploring the universe, was to come up at Mauna Kea in Hawaii. But protests by the locals and indigenous population has stalled the project.

"The construction was expected to start on Mauna Kea, Hawaii in 2015. However, it is now stalled due to the recent decision of the Supreme court of Hawaii revoking the construction permit on procedural grounds."

"The State of Hawaii agencies are working on the permit process following the prescribed procedure by the court. TMT is pursuing the
matter in consultation with the University of Hawaii (land lease holder) and other agencies. It seeks to construct TMT on Mauna Kea which is the preferred choice," said Bacham Eswar
Reddy, Programme Director.

However, given the importance of the project, in terms of finance and its scientific value, the project partners are also looking at alternate sites, both in the northern and southern
hemispheres. These include sites in Chile, Hanle, Ladakh and others which are all being evaluated for technical and logistical suitability.

"It is expected that on-site civil work on the
project may be delayed by about 18-24 months. However, work on telescope and observatory subsystems continues across the partnership," Mr Reddy added.

India is a 10 per cent partner in the TMT project, which includes China, Japan, Canada and the US. In India the project is being handled by the Ministry of Science and Technology and Department of Atomic Energy.

If the programme comes to India, it will open several doors.

"The project is expected to improve employment opportunities for the local people besides development of the region. TMT being
the largest optical and infrared telescope in the
northern hemisphere will strengthen the domestic programme of the country in this field and lead to several discoveries, which will inspire future generations.

"The project will also help develop state-of-the- art high end technologies and expertise in the country," an official.

Coverage must be made or at least it must be larger then the actual range of our longest range missile. Looks like A5 has long range then what they are actually saying.............:bounce:

are they gonna put 2 more satellites atleast at that constellation.

 

[mahesh]

they are backup satellites on ground to be ready in case anything goes wrong with the existing satellite in space, so that we can replace it fast and easy

Well, there was a story of 4 back up satellites prepared.
These two new SATs are being told to be better and of next generation, so a possible upgrade, expansion of NAVIC will take place soon.

ISRO to Launch Two New Meteorological Satellites

CHENNAI: Indian Space Research Organisation (ISRO) will be launching two new meteorological satellites in the second half of this year that will improve weather forecasting.

In an interview with The New Indian Express, ISRO chairman AS Kiran Kumar said the two new meteorological satellites will aid authorities and researchers make important decisions and draw conclusions with greater accuracy.

Kumar said that meteorological satellite INSAT-3DR, one of the satellites that will be launched will provide information on ocean vector winds that will help in climate research.

“INSAT-3DR is similar to INSAT-3D. We are also working on placing a scatterometer in the space for measuring ocean vector winds,” Kumar said.

ISRO has six operational satellites that deliver an array of information.

INSAT-3D is an advanced weather satellite of India configured with improved imaging systems and atmospheric sounder. It is designed for monitoring land and ocean surfaces, generating vertical profiles of the atmosphere in terms of temperature and humidity for weather forecasting and disaster warning.

It is a first Indian geostationary satellite, equipped with sounder instrument that provides frequent good quality atmospheric profiles (temperature, humidity) over Indian landmass and adjoining areas.

Meanwhile, ISRO is also planning to open up its Meteorological and Oceanographic Satellite Data Archival Centre (MOSDAC), which is a Space Applications Centre (SAC) located in Ahmedabad, for academic institutions involved in research and development activities in weather forecasting.

“MOSDAC has a wealth of information recorded from the year 2000 sourced from various Indian satellite missions like Megha-Tropiques, Saral, Kalpana-1, INSAT-3A and INSAT-3D along with other international weather satellites. This database can be of immense value to researchers. Usually, what we do is empirical analysis which requires large amount of data from 20 or 30 years. Now, ISRO is trying to make sure more and more researchers visit MOSDAC and allow them to access the archive data that will help them validate their research. We will also facilitate them with some computational systems,” Kiran Kumar said.

MOSDAC has completed a decade of meteorological and oceanographic satellite data
services for the nation this year. While congratulating MOSDAC on the occasion, Kiran
Kumar said the two new satellite launches this year will boost its database further.

To a query, ISRO chief acknowledged the fact that weather forecasting is a challenge in a tropical country like India. However, the space agency is trying to make the best use of the available technology to predict extreme weather events like heavy rainfall, cloud bursts and heatwaves.

Major highlights of MOSDAC services are - storehouse for space based weather and ocean
data, near real time meteorological and oceanographic data dissemination and free data to scientific and academic community.

Nitish Sharma​

KORBA,

Apr 30,

Nitish Sharma (25), a resident of Budhwari area of the district, got selected for Indian Space Research Organisation (ISRO). After Vikas Agarwal, Nitish is second person from the city to get this opportunity. After selection as Junior Works Manager (JWM) in UPSC, Nitish was waiting for Appointment letter from past six months. He was a topper of the day in the interviews conducted for the ISRO on February 20, at Delhi and he enjoys 10th position out of 2 lakh participants on All-India level. Vikas Agarwal who was selected earlier was on 5th in ranking. Suresh Sharma father of Nitish, retired from NTPC in 2014 as Dy Manager. He had a dream that Nitish should become an Engineer or IAS officer and was preparing for UPSC, but was very happy on his selection in ISRO. Till 10th standard Nitish studied in Korba and after that studied in Visakhapatnam till 12th standard. He completed his B E (Mechanical) in 2012 from Shankaracharya Engineering College, Bhilai.

After completing his engineering he took coaching for a year in New Delhi. As he scored less marks in UPSC he was selected as JWM. To complete his journey till ISRO he dedicated the credit to his mother Komal Sharma and father Suresh. Out of 2 lakh participants 300 were selected for the interview. Results were out on April 1st in which Nitish secured 10th position at all India level. Nitish would be joining as Scientist-C at ISRO Thiruvananthapuram center on May 10, 2016. After Scientist-C, A and B grade, position of D grade Scientist can be achieved only through promotion.

Good for both Nitish and ISRO.
Hardwork of one guy put him to success and generally high educated students go for companies, so ISRO also got good luck.

Isn't China installing/installed one which is the biggest in the world?

Isn't China installing/installed one which is the biggest in the world?

As far as I know, Asia's largest telescope is being settled in Nantital. So, obviously, China doesn't have biggest one.
In case of this telescope:
So, This telescope is largest in entire history of mankind and a joint venture between US, China, Japan, India and Canada. No larger telescope than this one is known to be in service or under construction is known.

 

[Kshatriya87]

they changed the name from navik to navic,

so navic must means navigation constellation.

@Indx TechStyle NAVIC confirmed to be "Navigation with Indian Constellation".

Refer the info in following article;

Also, while GPS, Glonass, Beidou and Galileo have or will have global coverage, Navic will be a regional system, extending up to 1,500kms outside India's borders. Also, while the others have a precision radius of 10cms (China's Beidou) to five metres (America's GPS), for Navic it is 20 metres on the civilian/commercial band and 10 metres on the military band. But these are early days and India will surely bridge these gaps over time.

But as you say, this is of course the information they have released. Things might actually be different in reality.

China on Schedule With World's Largest Radio Telescope to Search for Extraterrestrial Life

http://www.dailygalaxy.com/my_weblo...cope-to-search-for-extraterrestrial-life.html








"Having a more sensitive telescope, we can receive weaker and more distant radio messages," Wu Xiangping, director-general of the Chinese Astronomical Society, said of the 500-meter Aperture Spherical Radio Telescope (FAST) nestled in a bowl-shaped valley between hills in the southwestern province of Guizhou "It will help us to search for intelligent life outside of the galaxy and explore the origins of the universe," he added underscoring the China's race to be the first nation to discover the existence of an advanced alien civilization.




According to chief scientist from China’s National Astronomical Observations, Li Di, FAST will be able to scan up to twice more areas of the sky than Arecibo shown above, and it will have between three to five times the sensitivity. It’s in their hopes that if there is indeed alien life, this gargantuan will find it.

The region's karst topography -- a landscape of porous rock fissured with deep crevasses and underground caves and streams -- is ideal for draining rainwater and protecting the reflector. Unfortuately, citizens actually living in the area where the radio telescope will be built are being relocated. Some 2,000 families residing near the Pingtang and Luodian counties will be given $1,800 per individual for the forced relocation.

For years Chinese scientists have relied on "second hand" data collected by others in their research and the new telescope is expected to "greatly enhance" the country's capacity to observe outer space, Xinhua said. Beijing is accelerating its military-run multi-billion-dollar space exploration program, which it sees as a symbol of the country's progress. It has plans for a permanent orbiting station by 2020 and eventually to send a human to the moon.

The Chinese governmnet hopes that a more subtle benefit of the behemoth eye on the cosmos will intice some of the some of the brightest minds in science or astronomy studying abroad to return home to China. China is the leading nation in the world in the number of students it sends students abroad, especially for majors such as science or engineering.

Construction on the telescope started in March 2011 and is scheduled to finish this coming September, 2016.

Well, BeiDou is yet to reach Global Coverage. It will take 4 more years.
Undoubtedly, it's coverage is larger than Chinese.
Yet a signal from NAVIX was detected in Germany too.

The signal from IRNSS-1A was seen in Germany (with a big antenna though). I'd think the coverage is much larger than what is advertised
