It monitors the electromagnetic spectrum as part of ELINT. That is, it's listening in on enemies communication be it voice or data.

Nothing prepared me for what was to come..

Given the distance from Sriharikota, I was thinking it would be a small spot of flame moving leisurely across the sky.. and boy was I wrong!

Was alternating between glancing at the telecast and scanning the northern skies for a flame / smoke.. then I saw it. And for the first time in my life, said "holy sh!t" involuntarily.. The flame, a searing large one and the GSLV's pace was beyond blistering.. the rocket broke the haze cover a few seconds post lift off, and I barely managed 6 or 8 snaps before I lost track of the trail.

Such a majestic sight, and unfortunately most people did not care..

Will post some pics soon..

Sorry, if I sounded like a teen fanboy..


Just remembered, I completely forgot to upload the pic on BRF :oops: Dec 19th Launch of GSLV Mk2

Taken from a chennai roof top.. played with the color contrasts to make the flame stand out..

India space launch: One rocket, 29 satellites, three orbits

The Indian space agency places domestic and foreign satellites in three orbits on a single flight.


India has successfully placed a domestic intelligence-gathering satellite as well as smaller satellites from other countries in three different orbits on a single flight, a first for the nation and a low-cost option that could burnish its reputation for pioneering affordable options in space.

India's 436-kilogramme EMISAT intelligence satellite was launched on Monday along with 28 foreign ones from the Sriharikota launch pad in southeastern state of Andhra Pradesh, and was now orbiting 749 kilometres about the Earth, the state-run Indian Space Research Organisation (ISRO) said.

Twenty-four of the small satellites were from the United States, two from Lithuania and one each from Spain and Switzerland, the space agency said.

Also, since it is a higher risk mission, they didn't want the opposition to use it if things went wrong. Hence the direction to defer it for now.

Starting May, ISRO to launch a string of ‘defence’ satellites - Madhumathi D.S, The Hindu
Image


Between now and early 2020, the space above India looks set to see an unprecedented rush of satellites meant solely or mainly for the country’s military.

Starting May, the Indian Space Research Organisation (ISRO) plans to send up at least eight earth observation (EO) satellites of varied hues and at the rate of almost one a month.

Communication satellite GSAT-32 is also in the offing next year to replace GSAT-6A, which was lost in a failed launch and was meant to mainly serve the ground forces. Until now, such defence-use satellites were spaced out over a few years; or were put up only once a year as in the case of the Cartosat-2 series high-resolution imaging satellites.

Looking at the last three launches, we could even say the train has already started. HysIS, launched in November; Microsat-R in January; and the EMISAT sent into orbit on April 1 are all for what is called “strategic use”.

DRDO payloads

While traditionally, payloads for ISRO’s satellites come from the Space Applications Centre, the payloads of the Microsat-R and EMISAT were from the Defence Research and Development Organisation (DRDO), said officials, who spoke on condition of anonymity.

Soon after EMISAT’s launch, ISRO Chairman and Secretary, Department of Space, K.Sivan, announced that the next mission would be the radar imaging satellite RISAT-2B, followed by a high resolution mapping satellite Cartosat-3.

Both are understood to be useful militarily and seen as overdue assets.

Great news! About time too. Happy that ISRO has discarded the unnecessary "we are civilian onlee" tag.

Hope Modi 2.0 comes back in May and we see a doubling down on this. If Congress comes back, we can expect them to delay/deny these plans - as a CBM to Pakistan

Excellent. If we can detect launches very early on, we can fire our BMD for mid-course interception. This PDV-MK2 should be capable for Mid-course interception as it is or with some minor modification. especially in guidance.

The risat in list are sar imaging sats

Cartosat3 from wiki- will be able to image humans due to
10inch res... kh11 is the 4 inch sharp end of spear range

Cartosat-3 is a much more capable satellite, having a resolution of 25 cm (10").[1] It uses 1.2 m optics with 60% of weight removal compared to Cartosat-2. Other features include the use of adaptive optics, acousto optical devices, in-orbit focusing using MEMs and large area-light weight mirrors.[3]

TOI report has some interesting nuggets:

1) Cartosat 3 resolution is 20 cm (Cartosat-2 was 50 cm) - both very impressive numbers
2) Risat-2 series is lighter and has a 1m resolution
3) Gisat series will be multi-spectral (visible, near-infrared & thermal) - with a 50m - 1.5Km resolution
4) Gsat-32 for military communications, which replaces Gsat-6A which malfunctioned (I don't remember the 6A malfunctioning(

With internet frequently being cut in PoK, the first round of info is getting suppressed, maybe India should setup sats for mobile internet connectivity on the lines of Iridium, of course areas of conflict that we are interested in get it for free. US flies aircraft that acts as a virtual cell phone tower spoofing all mobile phones in the area to connect to it.

so, one could have a constellation of micro sats at 300km altitude that act as two way repeaters to some high end sat in MEO doing processing and back haul to ground stations, so the average cell phone doesn't need to change unlike Iridium that needs sat phones.

Satellite-killer not a one-off, India working on star wars armoury.

After successfully testing an anti-satellite (ASat) missile last month, India is now also working to develop other counterspace capabilities like directed energy weapons (DEWs) and co-orbital killers as well as the ability to protect its own satellites from electronic or physical attacks.

“We are working on a number of technologies like DEWs, lasers, electromagnetic pulse (EMP) and co-orbital weapons etc. I can’t divulge
the details, but we are taking them forward,” said DRDO chief G Satheesh Reddy on Saturday.

The A-Sat missile that destroyed the Microsat-R satellite, at an altitude of 283-km in the low-earth orbit (LEO) on March 27, was a “directascent, kinetic kill” weapon. It’s “feasible” to target multiple satellites with multiple launches of the three-stage interceptor missile, which can go up to 1,000 km into space," said the DRDO chief.

A coorbital weapon, in turn, is basically a satellite equipped with some explosive, weapon or DEW device, which is first put into orbit and then later manoeuvred to target the enemy satellite. Apart from these kinetic kill weapons, other ASAT weapons like lasers jammers, EMP and high-powered microwaves are being rapidly developed by China, which first tested an A-Sat missile against a LEO weather satellite in January 2007.

Trying to play catch-up, sources say India’s long-term aim is to develop A-Sat weapons against satellites in both LEO and GEO-synchronous orbits as a credible deterrence against emerging threats to its growing spacebased assets. “Conversely, EMP hardening of our satellites and sensors, apart from other measures, can be done to protect them from our adversaries,” said a source.

"There is a plan to launch mini-satellites on demand for the armed forces if the main satellites are targeted,” said a source. DRDO for long has also been running programmes on a wide variety of DEWs like high-energy lasers and highpowered microwaves capable of destroying aerial and ground-based targets, but whether they can be successfully developed into A-Sat weapons remains to be seen.

DRDO chief G Satheesh Reddy, on his part, said it was for the government to decide on the issue of weaponisation of A-Sat systems or the creation of a fullfledged Aerospace Military Command. “Space has gained importance in the military domain.

The best way to ensure security is to have deterrence,” he said. The DRDO chief made it clear that there was no move to conduct additional tests of the new A-Sat missile as of now.

“Though we tested the interceptor missile for an altitude below 300 km as a responsible nation after multiple simulations, it has the technical capability to go beyond 1,000 km. That will cover most of the orbiting satellites in LEO. For the same purpose, we don’t need more tests,” he said. The target satellite was hit with an accuracy of less than 10 cm, on par with “the best reported performances” of such A-Sat missiles worldwide. “So, it meets all our objectives.

The successful demonstration of ‘Mission Shakti’ has placed India in the elite club of three countries (US, Russia and China) possessing the A-Sat capability,” Reddy added.

ASAT is not, strictly speaking part of the space program, it's a DRDO project. please keep ASAT news to that thread.

Vikram hurt during practice, puts Chandrayaan-2 on bench

>BENGALURU: Vikram, the Lander on India’s ambitious mission that envisages to land a probe on Moon, has suffered minor injuries in two of its legs during a test late February, putting on the bench at least until May. But the need to find the most suitable launch window could see the mission take off only in the second half of the year.

A source in the know, said: “The rover and orbiter are in good health and tests met all the parameters. However, after the ‘Lander Drop Test’, we found that Vikram (the lander) needed to be strengthened in its legs. Prima facie, it appears that not all parameters were set correctly before the test, it could also be that the additional mass—a result of the new configuration—caused the problem.”
