They should have taken pictures. The coastguard could have. They must have taken pictures... Just not released it. Hope they declassify some pictures or video footage of the floater soon! Satellite operators give negative reviews of Indian regulator’s satellite-TV proposal “Who is going to pay to r...

RLV-TD is becoming X-37B equivalent! Not so fast! RLV-TD is still sub-orbital while X-37B is orbital. The task of returning to land on a runway from orbit will be a lot more challenging, but agreed that this is very exciting. In my opinion the RLV-TD should continue as its own programme toward beco...

nTripathi...say i want GPS coordinated of a building in pakistan or china..how will i put a reciever there or send a drone. I ofcourse dont understand how sat imagery can tell me GPS location..and if it does why do i need to put IRNSS in the air at all?? bit confused There are two concepts here: fi...

pardon my ignorance of GPS etc..Q1) how does one get accurate lat/long coordinates of a spot/point on foreign/enemy soil ?? if a missile has to reach a spot/point using GPS then we must know its exact lat/long. Q2) how accurate in meters is the Indian GPS system once all the 7 satellites are in orb...

ok, back to earth, can the IRNSS aid in spoofing the GPS or BDS receivers starting with the LoC first, so that the targets the terrorists are aiming for are shifted and instead they are led to predetermined ambush points. The shift shouldn't be linear, so somebody crossing at any point on a specifi...

OK congrats.. another PSLV success 8) However i am more interested to know about the shade which always comes in between the camera and the rocket clearing the launch pad and disrupt rocket's view. :lol: How can DD repeat same mistake again and again in such a flawless ISRO journey in recent past :...

Can we make an anti-sattelite weapon which will have surgical precision and would disable the satellite rather than blowing it apart. For example, a small robot thinggy going and attaching itself with the satellite and say fry its electronics, or damage its heat shield or damage its transponders or...

A KE hit usually changes the orbit of the sattelite (along with doing damage ofcourse), and the debris will usually go from circular to eliptical with microscopic eccentricity (i.e. will be barely even different from the original orbit) and therefore will not impact any other satelite. I could not ...

Is it only a software encryption issue or there is some hardware aspect to it. I was wondering how much secure we can keep this service from ChiPakus. If it's just an encryption issues, I am sure it will be a matter of time before they get their hands to it. There are ways to avoid hacking of milit...

When it comes to real war situations - I was of the idea that Chinese & Americans have the capability to shoot down Satellites of other countries via some powerful LASER emitting machine or something similar and thus prevent their enemies from exploiting GPS technology to gain advantages for th...

No. I was just being sarcastic. Even though chinese would want the general use of Beidou-2 in the asia-pacific., specific countries will definitely have reservations using chinese gps. I noticed the sarcasm disha... but look at the picture here: you have more than 4000 posts and i have less than 20...

Will the chinese and pakistanis be able to access the IRNSS? Could it be turned up against us in any fashion? Yes, people in China and Pakistan will be able to use IRNSS but only the standard positioning service (accuracy of 10-20 metres) not the sub-30 cm authorized service. However, China and Pak...

once the INRSS is in place would it be possible to block all GPS signals in India ? at times of war for example ? well, GPS is operated by USA so in a situation of war they can selectively block the coverage of their positioning service in any region of the world and for any duration! However, I be...

How would you integrate into Chinese 'GPS' signals? Using mandarin APIs? are you talking about merging beidou and irnss coverage areas?... well that is far from becoming a reality. Military of Pakistan is an authorized user of chinese system and India will not like its assets used in a way that mak...

GPS and Glonass, the only "true" global constellations need 32 and 24 satellites for their full constellation. The Chinese system is a global constellation only in name, as their satellites are in highly elliptical orbits and spend most of their time over China. why would china purposely ...

Budget 2016 gives Major boost to Department of Space. In a boost to the Department of Space (DoS), the Union budget 2016-17 allocated Rs 7509 crore to the department, an increase of around Rs 550 crore as compared to the last budget. Of the Rs 7509 crore budget allocation, Rs 1509 crore has been ea...

a mission to Lagrange point to study the Sun, the second moon mission and adoption of System on Chip as well as reducing weight by using composites to build the satellite chassis >The Aditya-1 (to lagrange point) will not occur before 2018. We have no reports on any ongoing work on building the spa...

No. Cheaper fusion, fission (thorium), and renewable technologies will come online and make the project irrelevant. There is enough estimated H3 on moon to cater energy needs of humans for next 10,000 years. So it is safe to say that the project will not become irrelevant . However it may change in...

Tripathi ji, I think GSAT 11 is built on I-4k bus (4 ton class satellites). Correct me if I'm wrong. Beyond the i-3K standard bus, ISRO is going to use unified bus for satellites in 4000-6000 kg class. Earlier they were developing the i-4K, and GSAT-11 is associated with this old information in tho...

It appears ISRO is upgrading its generation of satellite-tech in next couple of years! From 2015 to 2018 time-frame, some feature upgrades to next satellites: 1. Unfurlable antenna (GSAT-6) 2. High capacity modular bus: i-6K (GSAT-11, GSAT-19E) 3. Electric propulsion (GSAT-9, GSAT-19E, GSAT-Ka) 4. S...

How much deep we may have to dig on moon surface to find H3? the presence of H3 on moon is due to solar winds. and since deposition is the source, it is safe to say that H3 will be found adsorbed right at the surface and in the top couple of metres through historical sheet deposition of soil since ...

"Isro all ready for Chandrayaan II, says its chairman Kiran Kumar" Wonderful news, but what does 'all ready' mean, that the mission is going to take place soon? Late this year, or early next? Originally, it was planned for 2017-end, has it now been pushed forward? Great, if it has! Don't ...

Looks like there is no change in budget for space 6K crores last year and this year too "In a boost to the Department of Space (DoS), the Union budget 2016-17 allocated Rs 7509 crore to the department, an increase of around Rs 550 crore as compared to the last budget. Of the Rs 7509 crore budg...

Most powerful variant of PSLV XL thus far.

well almost all irnss satellites are 1425 kg and also irnss-1d was launched into the same longitude... hence i dont see anyhting that suggests that this is most powerful version of 'pslv xl'!! please clarify...

Well, on the contrary, I think the nomenclature used by ISRO is quite beautiful in its way due to its simplicity... Easy to remember and keep track of! Further, not naming the launch vehicles and satellites some legendary names keeps the space programme away from our "secular" politics!! :p

FROM INDIANEXPRESS ARTICLE: “This ScatSat satellite will measure the wind speed and it’s direction over the ocean. It can predict the formation of cyclones, about 4-5 days in advance. This time period is very crucial in saving lives,” Tapan Mishra (SAC) said about the satellite that will carry a pay...

What about the PSLV carrying two primary payloads for which the re-ignition test was done!?

So other than routine launches, new things we can expect in 2016 are:
1. RLV
2. Operational PS4 restart
3. LVM3 D1 should occur in Dec (fingers crossed)
4. Ion propulsion? anybody??

Can anyone provide me a clarity on ISRO launches next year after the IRNSS is completed?
