Well i´m all for developing


Wrong. Facists aren´t racists. I have nothing against indians who have no indian culture. I´m not against peoples genetics.

Wrong. You are pure racist. You have proved it many times in your posts.

kinetic anti satellite weapons are still in their infancy.. the Chinese test was only successful because the satellite being killed was sending a homing beacon to the missile, which will not be the case when targeting foreign satellites..

You are reaching there mate! How do you know that? You might as well just claim the satellite was pre-programed to be hit. What's the purpose of doing a self cheating test?

But you are right that kinetic anti satellite weapon technology is far from mature. The problem is not about trajectory tracking which by the way can be done easily without following "beacons". The difficulty is distance and speed. It is one thing to shoot down a dead or defenseless commercial satellite, it is a complete different matter when targeting a military satellite. Military satellites typically operate at much higher altitude and are able to maneuver themselves in space. The longer distance allows them more time to react. And because the satellite and the rocket are approaching each other at extremely relative high speed, all it takes is a slight change in orbit to avoid the collision.

sounds Awesome !
first time in 200 years those gypsies and Europeans are scared of Asians.
Just Keep Clam,
and
Develop Your Missiles

nobody is scared about idiots who build a weapon that only takes themself out of the game, blocking humanity from space and ends the human race because we will be not able to fend off asteroids in the case needed for hundreds of years.

Exactly!

Anti satellite weapons are a crime against progress and humanity. They are laughable and the best example for the idiocy of the human race.

no crime... actually, humanity doesn't need 99 percent of the satellites in earth orbit.

I am sorry for using word gypsies I was depressed

purpose was to create media hype, and a talking point for the chinese, as is the purpose of all publicized tests.. as any country who has long range missiles, has the capability to target LEO satellites.. but no one was doing that because of the potential problems associated with the debris fallout.. before the Chinese started and the U.S.retaliated subsequently..

as for a homing beacon, I read it somewhere that this was the case..

even if the homing signal report was unsubstantiated, still killing an LEO satellite, is far different from targeting a geo stationary or geo synchronous satellite, which would actually matter during times of war..

 

[jamahir]

we also dont need 99% of humans in 3rd world. I suggest ethnic biological agents would be a fine metjod in your eyes too then

we also don't need any mba or business school or stock exchange or capitalist bank especially in the western world... let us be even more precise in the selection of biological agents.

what are those 99 percent satellites for... military gps and comm, cell phone relay, tv relay, spy satellites ( so-called remote sensing ) etc... all of useless purpose in the end.

if anything, a single world body ( like uno ) should have been responsible for managing a very few number of navigational satellites and communication... for earth observation, there is the "international space station".

what is laughable about this??

Creating media hype?I It takes one to know one I guess. But they are just so dumb that even amateurs like you can figure out, huh? I believe you read it somewhere. But who ever wrote that garbage has not even the most basic idea of the space science. Locating and predicting the movement of a satellite in space has long been well understood. You don't need beacons, heck you don't even need a radar. Just a good telescope will do (well, in theory at least). Eugene Shoemaker and David Levy predicted a comet was going to hit Jupiter over a year before it happened.

buddy, I do remember distinctly that some signal was being relayed by the satellite to the missile guidance, and it was used to determine the success of the test, according to a write up about it.. whether it was used to home in was speculative, but likely.. Chinese media being so closed, most of the information is speculative about the test..

I'm very highly educated in fields related to technology and science, probably more so than you, I'm saying probably as I don't know your exact academic qualifications, if you could elaborate on that I could happily revise my opinion regarding the matter..

pray tell me, what did the test benefit to the Chinese or any other human on the planet, apart from tell us what we already know, that any LEO satellite can potentially be targeted by any country with a slightly advanced missile development.. but long range missiles are meant for stationary targets and have an error margin greater than the cross sectional area of any satellite.. if you had any basic knowledge of physics, you would realize that targeting that size of cross section at that velocity will have a wide margin of error, if unaided by a feedback signal..

was just done to create a talking point, and going by the discussion in threads like these, it is mission accomplished for the Chinese..

congratulations! !

please let me know when China can target any satellite in any orbit belonging to any other country successfully, I'm sure it'll not happen in my lifetime, but please feel free to educate me when it does.. LOL

Well, you can always use a small homing device on the satellite. That is bug the device in space itself by some trasmitting devices.

such transmitter wouldn't be present in military satellites.. this whole thread is far removed from reality.. please refer the below..

While it has been suggested that a country intercepting the satellites another country in a conflict, namely between China and the United States, could seriously hinder the latter's military operations, the ease of shooting down orbiting satellites and their effects on operations has been questioned. Although satellites have been successfully intercepted at low orbiting altitudes, the tracking of military satellites for a length of time would be less accurate than previous commercial or defective intercepts that did not employ any defensive measure like simple inclination changes. Depending on the level of tracking capabilities, the interceptor would have to pre-determine the point of impact while compensating for the satellite's lateral movement and the time for the interceptor to climb and move; U.S.intelligence, surveillance and reconnaissance(ISR) satellites orbit at about 800 km (500 mi) high and move at 7.5 km/s (4.7 mi/s), so a Chinese Intermediate-range ballistic missilewould need to compensate for 1,350 km (840 mi) of movement in the three minutes it takes to boost to that altitude. Even if an ISR satellite is knocked out, the U.S. possess an extensive array of manned and unmanned ISR aircraft that could perform missions at standoff ranges from Chinese land-based air defenses, making them somewhat higher priority targets that would consume fewer resources to better engage.[16]

Global Positioning System and communications satellites orbit at higher altitudes of 20,000 km (12,000 mi) and 36,000 km (22,000 mi) respectively, putting them out of range of solid-fueledIntercontinental ballistic missiles. Liquid-fueled space launch vehicles could reach those altitudes, but they are more time-consuming to launch and could be attacked on the ground before being able to launch in rapid succession. The constellation of 30 GPS satellites provides redundancy where at least four satellites can be received in six orbital planes at any one time, so an attacker would need to disable at least six satellites to disrupt the network. Even if this is achieved, signal degradation only lasts for 95 minutes, leaving little time to take much decisive action, and backup inertial navigation systems (INS) would still be available for relatively accurate movement as well as laser guidance for weapons targeting. For communications, the Naval Telecommunications System (NTS) used by the U.S. Navy uses three elements: tactical communications among a battle group; long-haul communications between shore-based forward Naval Communications Stations (NAVCOMSTAs) and deployed afloat units; and strategic communication connecting NAVCOMSTAs with National Command Authorities (NCA). The first two elements use line-of-sight (25–30 km (13–16 nmi; 16–19 mi)) and extended line-of-sight (300–500 km (160–270 nmi; 190–310 mi)) radios respectively, so only strategic communications are dependent on satellites. China would prefer to cut off deployed units from each other and then negotiate with the NCA to have the battle group withdraw or stand down, but ASATs could only achieve the opposite. Even if somehow a communications satellite were hit, a battle group could still perform its missions in the absence of direct guidance from the NCA.
