ISRO CHIEF: GAGAN IS SUPERIOR TO ALL AVAILABLE GPS

[Mr.Nair]

By your definition, USA Hubble is not qualified to be a space telescope, because "its purpose to view distant planet". I don't know what is the telescope then. By the way, the Lunar-based telescope we are talking about is not on the Moon Rover, it is on the Moon Lander.

Nobody wants to certify ISRO's space program. It has accomplished a lot, but this is not my point. My point has been India in general is good at announcing plans, but no known for executing the plans and delivering the results. From your space programs such as GSLV-3, manned space flight, moon landing, to your jet engines, LCA, Arjun, MMRCA, to the plan to be superpower in 2012, almost none has escape this fate. Hence big mouth comments.

When i talked telescope you talked land rover.Is the land rover purpose is to view distant planet or a rover to land on planet ! Is the hubble telescope designed to land on any planet surface or to observe distant planet ! India is a democracy and have free media access and project announcement will happen to the public and not like secretive chinese nature.You don't have habit of announcing any project until it delivers so you don't know whether a project break deadline or not.Because every thing from military to space tech is secret in china.

Chinese navigation satellite Beidou first launch in year 2000 and you have 17 healthy satellites in orbit from past 15 years.India launched first satellite in 2013 for IRNSS,just 2 year back and launched 4 satellite into orbit until today.It's like 2 launches/year.So is it OK to tell that why chinese take long time for its completion of beidou program as far as number of satellites is concerned even though it started 15 years back.

“GAGAN will be the world’s most advanced air navigation system and further reinforces India’s leadership in the forefront of air navigation. GAGAN will greatly improve safety, reduce congestion and enhance communications to meet India’s growing air traffic management needs,”

- Andy Zogg, VP, Command & Control Systems, Raytheon Network Centric Systems

Raytheon is AAI's sub-contractor for building GAGAN SBAS Ground Stations in India.
Raytheon Wins $82M Air Navigation Contract From India

The reason why ISRO claims GAGAN to be the best in class is the unique positioning of its GEO and GSO satellites in orbit and its advanced ionospheric algorithm - The unique Geostationary Earth Orbit (GEO) /Geo Synchronous Orbit (GSO) constellation design provides a position accuracy of better than 15 metre for longer duration of 20 hours in a day even with 4 satellites (out of the total 7 in the constellation). GAGAN ionospheric algorithm known as ISRO GIVE Model-Multi-Layer Data Fusion (IGM-MLDF) developed by ISRO is operational in the implemented GAGAN System which is a significant breakthrough in this concern.

India has become the third country in the world to have such precision approach capabilities with GAGAN being the first SBAS system in the world to serve the equatorial region.

Back in early 2000's to begin implementing a satellite-based augmentation system over the Indian airspace, Wide Area Augmentation System (WAAS) codes for L1 frequency and L5 frequency were obtained by India from the United States Air Force and U.S Department of Defense. Good to see the experience gained through the same has finally paid off in GAGAN's development process.

AFAIK the constellation of 7 satellites is for IRNSS. GAGAN is entirely a different thing, may be in future GAGAN will also relay IRNSS augmented signal along with GPS.

Thanks for pointing it out - corrected - From a regional perspective, if both IRNSS and GAGAN are optimized - it will not only provide the optimal coverage but more advantages (for example, availability, reduced satellite count, SBAS of IRNSS) will be achieved with less (without additional) satellites.

Till date the navigation and the augmentation system (satellites) have been different in every GNSS. Here's a research paper published by University of Calgary, Canada on the same -

Where did I talk about the lunar-based telescope on land rover? What I said is Chinese Lunar-based telescope was launched with Chang'e-3 mission in 2013. You did not know there were two parts in Chang'e-3, Lander and Rover, do you? Or you just cross-eyed? Google China LUT telescope to learn more.

Now you blame your numerous and habitual grandiose announcements, delays and cancellations on your democracy and the media? We all know your media is notoriously known for sensationalizing everything, but announcements are made by your government officers not media. Just who announced "India will be a superpower by 2012" in 2009?

While Chinese military programs may be under wrap for a reason, Chinese space programs and other mega projects are all announced to the public before hand. We do what we said, and we say what we did, generally on time and in budget.

 

[punit]

So ? No one stays on the top forever accept it and have a sound sleep.


Ha? Absurd logic, it's like saying why announce that wr have discovered water on mar or moon we should wait till we make use of it.

disclose when u have all the proofs. if gagan is better than Standard GPS come with data and facts not mere statement.

ISRO please do not acquire bad habits from DRDO. Let your work do the talking.

Too late. ISRO claim that they will surpass NASA in ten years. I wonder in what area of space exploration or space science Would NASA be behind ISRO in ten years. Would that be Mars exploration, space launch capability, human space flight.... Of these I think the best chance is actually human space flight as NASA has no means of sending human to space now....

An idiot is an idiot but a stupid is a headache. First learn what is GAGAN it is developed to correct GPS signal with better accuracy. Your country never launched an apple, so please don't bother to criticise others.

I think our military is in trouble as we have been using GPS since early 90s without GAGAN. I hope India would teach American military about shortfalls of GPS and allow us to use the more advanced GAGAN.

Do you really think same satellites are being used for GPS Navigation. Small Navigation Satellites have a life span of no more than 15 to 20 years. During that time new satellites with new technology have been launched.
I am working on new generation Transmitters and receivers for GPS so i know how advanced GPS technology is right now. New Generation satellites are one of the most advanced and compact.

What we should be mor worried about is space junk. Ever looked at an image of our plannet from outside.
No wonder Aliens don't visit our planet.

I was being sarcastic.

Gagan is integrated with gps u dumb shit,first know what it is.
The whole purpose of gagan is to improve accuracy over Indian region,first have some base knowledge of what you are arguing and then open your mouth,but in your case its best to keep it shut.
Gagan means gps aided geo augmented navigation, basically it ptovoides gps signals with refernce points from earthstation(15 in India) this referencing is like triangularization and improve the accuracy of navigation.

adjust ur panties.. don't twist it no one claimed as such.

You are an American!!! then I am a Pakistani! and windjammer is an Indian.

Thats why i called you stupid. You can't even troll sensibly.

Lol ok but Still many here believe that US is operating 30 year old sats.

 

[Kashmiri Pandit]

Have ISRO released there data of Methane sensor ???

When i am talking about telescope, what the lunar based telescope have to do with a space telescope dedicate to see distant planet.Don't twist matter for the sake of argument.Is some body told you that india become super power by 2009 blah blah or is our prime minister told you that we will become super power in 2009 blah blah ! If you do what you said then why mars mission failed in your first attempt? Why you have only 17 healthy satellites for navigation in orbit when the project started 15 years back ! We can understand the frustration from your side, when india about to achieve critical project with success.

Besides the European Space Agency, India becomes the fourth country after the US, Russia and Japan to launch a dedicated astronomy satellite or space telescope.China launching space observatory telescope by 2016 and Japan will be launching the advanced Astro-H. Japanese Space Agency JAXA reported in April 2015 that all observation instruments have been installed in Astro-H and “preparations for launch are turning the final corner.

Please don't tell that China have a dedicated space observatory telescope in orbit when you are about to launch in 2016 or we have to agree that you have one since you said so !

Yeah same like indian cow's milk is nutritious then other country's cow milk .
