Military using 13 satellites to keep eye on foes

NEW DELHI: With the successful launch of "eye in the sky" Cartosat-2E+ satellite with surveillance capabilities last Friday, the total number of satellites being used for military purpose has gone up to 13, an Isro source said.
These satellites, which can be used for surveillance and mapping border areas, are primarily used for keeping an eye on enemies both on land and sea+ .

"Most of these remote-sensing satellites are placed in the near-earth orbit. Placing these satellites at the sun-synchronous polar orbit (about 200-1,200 km above the Earth's surface) helps in better scanning of the earth. However, some of these satellites have also been put in the geo orbit," the source said. The recently launched 712-kg Cartosat-2 series spacecraft is an advanced remote sensing satellite+ capable of providing scene-specific spot imagery.

The Cartosat-2 can accurately spot objects within a square of 0.6 metre by 0.6 metres.

"The 13 satellites used by the military for surveillance include Cartosat 1 and 2 series and Risat-1 and Risat-2+ ," the Isro source said.

The Navy also uses Gsat-7 for real-time communication among its warships, submarines, aircraft and land systems. India also has the capability to launch anti-satellite weapon (ASAT), which is meant to destroy enemy satellites.

Only the US, Russia, and China are known to have developed these weapons.

However, Isro has no intention of engaging in such an anti-satellite weapon project.

JAPAN WARNS CHINA OVER WARSHIP AND SUBMARINES SAILING NEAR CONTESTED WATERS

 

[Guest]

are you sure that chinese nuke sub surfaced because japnese would attack?…………

did anyone attack foreign nuke subs in peaceful time?


perhas japanese want to be the first one ……


guy,093b hardly wanders alone.


093b usually acompany 094 while 094 usually carry dozens of nuke ICBM.

maybe japanese feel it funny to mess nuke ICBM.

I am saying that the submarine commander either panicked like a greenhorn, or is completely stupid.

No one would've attacked the submarine, all the more reason not to surface.

I don't know how Chinese sub maneuver plans are, but normally, an attack submarine is the escort and not the escorted. SSN protected others, It doesn't need protection from others.

94 seems to be the SSBN, now why would the SSBN go close to Japanese and expose Its signature when It has missiles which can reach 8000km ? and what was It planning If It did go close to Japan, use the 8000km range ICBM to reach a few hundred kms ?

east china sea is quite shallow and is not fit for nuke subs.
china lacks of safe blue sea fit for the activity of nuke subs,like okhotsk sea of russia.

it is more fit for conventional subs .

it is surely that the 093b was accompanying/guarding 094.

and japanese did not found 094.

093b's surfacing might cover the actitvity of 094 and dsstract japanese attention,perhaps.

anyhow,094 sneaked back without be detected.

guy,USA is too far.

094 often cruise through the island chain for a good spot launching its ICBM to USA.

case might be that chinese nuke subs fleet were detected on way back homeport.
one of the fleet surfaced.

maybe someday when 12000km JL3 ICBM is ready, chinese SSBN need not cross island chains any more.

So you are saying 093 might have tried to shield 094 that can happen but again It will happen only in war like situation. And that would be done again as a surrender and last resort measure, Its like the Soviets flying Mi24 as escorts along their transport planes to take missile hits from stinger and save transport plane. Here I don't think the Japs attacked by launching torpedo.

If the depth is shallow both 094 and 093 would've been tracked, there was no need to sent these submarines in contested waters under Japanese watch, unless PLAN wanted a war. You don't expose your best weapon and not fight the war.

If you say the 094 was going towards Pacific, then the common sense says moving it from and area where surveillance is low and not a disputed area, where Japan, USA and Korea all are on look out for any intruder. Perhaps use an oil tanker or cargo vessel and move the Submarine under the huge ship to shield it and cover her noise.

china does not face open ocean. the only blue sea fit for nuke sub fleet is southchina sea,but it is too far away from USA and not a good spot launch 8000KM JL2 ICBM.

Thus ,CHinese nuke sub fleets have to cross the islands chain into the Pacific.
And they often have to look for new available crusing lanes during the peaceful time.

Maybe,the event is just one of those tries, although east China sea is obviously too shallow to be fit for the activity of nuke fleets.

If someday Taiwan were to be taken back by PRC, CHina could face the Pacific and such Geography curse could be relieved.



frankly speaking, some conclusions can be drawn with the event.


1. CHinese nuke sub fleets are more active than people usually thought.

2. To trail/detect Chinese sub fleets is not so easy for USA/Japan as people thought.
According to the news, even now Japanese does not know how many CHinese nuke subs on hell were there at that time,except the one surfacing itself.

From what I know the Chinese submarine base is in South China sea, and they could've easily gone into Pacific from there avoiding the Japanese net.

But according to you the SSBN took a longer route and went inside Japanese net, to reach Pacific, which was the 1st net, after that there was the US net near Guam etc.

1. Off course Nuclear Submarines have to do strategic patrols, that what they are made for, not sitting inside harbor taking rust.

2. Well the Japs got the submarine to surface and reveal its true signature, now USA will pick the submarine in the sea, as soon as It leaves the harbor and keep a tail of its movements.
And If the news is correct than Japanese saw the Chinese sub, showing all its secrets, will help them to track all the improved type 93 and USA aswell wherever they are.

case might be more complicated than you thought.

USA/Japan might detect some signal of 'some subs' active there ,but did not know which type they(it) was , how many subs wre threre and which country it(they) belonged to .......

thus they tried to trail it(them),until one CHinese 093b surfaced in east China sea.but at the end, japanese might still not get to know how many subs were there on hell and where the rest were........

As for 093B surfacing, the 093B might surface perhaps because it assured it was safe(already within the air cover of PLAAF) ,or perhaps because it wanted to humiliate Japanese or was humilated by Japanese....nobody here knew it.


BTW, Chinese nuke fleets have a homeport in Qingdao beside East CHina sea.

Submarine warfare involves building database, means the software has to know the signature of the vessel to update her data base so that they can track the vessel, 100s of km away in the noisy sea.

USA has undersea network which tracks subs from 1000km away and It is a good chance that Japan also have similar network around China.

Now according to you USA and Japan might be confused about the sub, and which country it belonged to since may be according to you all the countries in the region, North Korea, China, Vietnam etc have nuclear submarines.

And they were still confused who will sent their submarine to a place which China claims as her own, may be Russians perhaps or even Indian. So to clear their confusion Chinese commander got his boat to surface and make It clear.

Mostly the submarine episode is to test it's submarine stealthy or to test japanese defenses or to collect SIGNIT.

russian nuke sub fleets are active there too.

But the japs are saying something else they sent a destroyer to tail the submarine not their Subs ...

Aren't most of their navy arsenal just Soviet era relics? I doubt their newer subs get detected that easily
