Jamming of Satellites
-
Back in 2004, the U.S. Air Force suggested that they might be willing to mess with commercial satellites, if they were aiding an American foe. The idea drew howls from outside observers. And, for a while, it seemed destined for an extremely quiet corner of flyboy doctrine.

But now, the Israelis are picking up where their American counterparts left off, Defense News' Barbara Opall-Rome reports. Fed up with Hezbollah's Al-Manar TV broadcasts -- which stayed on the air, despite repeated aerial and electronic attacks -- the Sabras are now talking publicly about "disrupt[ing] transmissions of enemy programming carried by commercial satellites."
“No doubt, we understand the power of the media, public opinion and mass psychology,” said [Maj. Gen. Ido] Nehushtan, who is responsible for IDF modernization planning. “Al-Manar is a liability, and we’re going to have to improve our ability to counter this threat...”
...the only way to ensure persistent, reliable, wide-area broadcast denial is through an anti-communication satellite system. Israel must develop the means to surgically target signals serving Hizbollah without damaging the spacecraft or disrupting operations of other customers serviced by the broadcast frequencies, he said...
[But] according to [an Israeli] executive, jamming a communications satellite is “like interfering with civil aviation. You can do it, but it’s against international law and you’ll be subject to all kinds of lawsuits.”
It is technologically impossible, he said, to selectively jam only those satellite signals that carry enemy broadcasts.
“Everything goes out as a single beam, and it is impossible to jam only those channels viewed as a threat,” the executive said. “If you make the decision to interfere with one [satellite signal], then you must be prepared to face the consequences of the collateral damage incurred to the many other legitimate users of the signal.”
Robert Ames, chief executive of the Satellite Users Interference Reduction Group... said it is relatively easy to jam a specific satellite transponder.
“Transponders are separated by frequency,” he said. “All you have to do is know the frequency which it operates on and then put up a signal that is stronger than the programming carrier of the satellite...
Satellite interference capabilities have been around since the mid-1970s, he added. “But if the Israelis are talking about technological challenges, I assume they are aiming for a capability that goes way beyond what our companies have experienced to date.”
I think Singapore should take a look at this technology, both to protect our own communication satellites from jamming and at the same time have the capability to jam others satellites as well. This technology is especially important in a day where both the civilians and the military of the world is increasingly dependant on satellites. One good example is GPS. We can cooperate with the Isaelis on this.

I heard SG got spy satelite, any more info on this
-
I can confirm this. Our satellites are developed together wit the Isarelis, there is a ST article not too long ago. See if any of the MN bros have it to show you.Originally posted by Texcoco II:I heard SG got spy satelite, any more info on this -
Can the jamming or shooting down of satellites be considered an act of aggression?
-
yup it's quite old news that singapore had cooperated with israel on spy satellites....with singapore providing the funds and israelis contributed the tech for the Ofeq Satellites....btw i heard that the spy satellites can only last like 5 years with all the wear and tear in space...like quite 'bo hua' for such an exp proj costing around US$1bil!

Not forgetting those micro satellites that NUS launched into space. Those carry cameras that have resolution of up to 10 meters, which is good enough to spot tanks, planes and stuff. -
You heard of the starwar program?Originally posted by Croaking_Toad:Can the jamming or shooting down of satellites be considered an act of aggression? -
isn't that like shooting down ballistic missles or warheads?Originally posted by banzie:You heard of the starwar program? -
I believe a milsat program covers the cost of replacement satellites.Originally posted by Don©:X2 Singapore came up with the funding and the israelis provided the technology.

The Ofeq class satellites, are very very powerful for our region. -

Some information on the older Ofeq 3 sats. South Africa is one of the co-users of it. -
Yeah, that's the one of Reagan's brainchild. Got scrapped coz of budget. Was it resuscitated by Bush Sr.?Originally posted by beavan:isn't that like shooting down ballistic missles or warheads?
Takes care of ICBM. Not sure about satellites.
How high above ground still considered a sovereignty's airspace? -
do antisatellite missiles exist?
-
the USAF had a missile, called ASAT..Originally posted by SingaporeMacross:do antisatellite missiles exist? -
fired frm an F-15 lolOriginally posted by LazerLordz:the USAF had a missile, called ASAT.. -
yeap read it in some book before.real special way of firing it.Originally posted by |-|05|:fired frm an F-15 lol -
It launch during a vertical climb
-
Hmm...maybe we should consider buying a couple of these ASAT missiles? That is if USA allows us to buy.Originally posted by |-|05|:fired frm an F-15 lol -
and who's satellites do u want to shoot down?Originally posted by tankee1981:Hmm...maybe we should consider buying a couple of these ASAT missiles? That is if USA allows us to buy. -
It's a cute little missle.I have a picture of it somewhere in my room hah.
orange/yellow round nose cone with a 2 stage rocket if i'm not wrong -
If I remember correctly, the missile has to be launched at the upper limit of the Eagle's flight ceiling, in a vertical climb/particular parabolic flight curve.. to let the rocket motor fire long enough to exit suborbital space.Originally posted by |-|05|:It's a cute little missle.I have a picture of it somewhere in my room hah.

Taken frm World AirPower Journal 1992 summer
Much effort was expended on fitting the F15 witha Vought anti-Satellite missle for deployment with a Fighter Interceptor Sqn on each coast.The missile was launched from a zoom climb at about 80,000ft two rocket stages carrying it towards the satellite.Homing was by infra-red.No warhead was fiited as the kinetic energy of the impact was more then sufficient to destory the orbiting vehicle.The ASAT program ended after one successful launch as it was felt to violate a space testing treaty.
My scanner spoilt to i cant scan the article.sorry guys.
