Priznanja potpune tehničke inferiornosti Ukropistana. Već se mašta i nekakvim “povoljnim mirovima”:
Russian jamming has become so effective that Ukraine — as well as the US and NATO — can no longer assume that Joint Direct Attack Munition glide bombs and other smart weapons will hit their targets.
That's the conclusion of an analysis by Britain's Royal United Services Institute. "Jamming is not causing the JDAMs to stop working, but it is risking their accuracy," according to RUSI researcher Thomas Withington.
While anti-jamming upgrades to JDAM may mitigate the problem, Russian electronic-warfare systems can simply drown out the GPS guidance signal from satellites. "The problem may well be the sheer power of the jamming signal that can be brought to bear," Withington said.
The warning comes after Pentagon documents leaked in April revealed concerns that Russian jamming was reducing the accuracy of American guided weapons, including JDAM as well as HIMARS rockets.
The effect on JDAM is particularly significant, as it is arguably the simplest and most cost-effective smart bomb. By attaching fins and a GPS guidance system to cheap, old-fashioned "dumb" bombs, Ukraine could produce long-range guided weapons at a fraction of the cost of special precision-guided munitions that are in short supply.
The JDAM Extended Range bombs sent to Ukraine reportedly have a range of up to 50 miles, allowing launch aircraft to remain safely out of range of Russian air defenses.
That Russia is developing countermeasures shouldn't be surprising. All weapons eventually lose some effectiveness as the enemy adapts. Nor is it a secret that the Russian military, like its Soviet predecessor, devoted great effort to developing a variety of electronic-warfare systems.
In particular, Withington pointed to the Russian Army's R-330Zh Zhitel, a mobile truck-mounted jamming system specifically designed to disrupt GPS and satellite communications in the 100 MHz to 2 GHz wavebands. "Signals from the U.S. GPS satellites which JDAM kits use are transmitted on wavebands from 1.164 GHz to 1.575 GHz," according to Worthington. "These fall squarely within the R-330Zh's catchment area."

Worthington claims to have seen official documents that put the R-330Zh range at 18.6 miles, with a 10kW-strong jamming signal. This is "notably stronger than the strength of the GPS signal arriving from space," he noted. "Moreover, the closer the GPS receiver is to the R-330Zh's jamming antenna, the stronger the jamming signal becomes."
In theory, the Selective Availability Anti-Spoofing Module upgrade to JDAM in the early 2000s should ensure that JDAM will only respond to authorized M-Code encrypted military GPS signals. However, Russian jammers may still be able to disrupt the signals through "sheer brute force" jamming beams, Withington said.
Russia could also intercept M-Code signals and retransmit them with slight alterations to a JDAM, causing the bomb to miss. Efforts to bypassing Russian interference by using signals from multiple GPS satellites could in turn be countered by employing multiple jammers.
Russia's counter-GPS efforts are part of a massive electronic-warfare campaign that has also disrupted Ukrainian radio communications and drone operations.
Russian forces "now employ approximately one major EW system per 10 kilometers [6.2 miles] of frontage, usually situated approximately 7 kilometers [4.3 miles] from the frontline," according a recent RUSI report on Russian tactics. This jamming has contributed to a Ukrainian drone loss rate that RUSI estimates to be as high as 10,000 UAVs per month.

According to the RUSI report, Russian EW troops are also "highly capable" at intercepting and decrypting Ukrainian radio communications. In one case, they appeared to intercept and decode an encrypted radio message from Ukrainian troops calling in a fire mission in real time, allowing Russian commanders to send "pre-emptive warning" to their units.

Sta je sada tu novo? Isto to je rekao i Stoltenberg vise puta a sigurno ce nakon prestanka rata uci u NATO, hoce Orban da pokaze muda kojih nema.Sijarto: Nema razgovora o članstvu Kijeva dok traje sukob
Pogledajte prilog 1371681
Mađarska Vlada je nepokolebljiva u stavu da se o članstvu Ukrajine u NATO-u ne može razgovarati dok traje oružani sukob u toj zemlji, izjavio je mađarski ministar spoljnih poslova i trgovine Peter Sijarto.
Na pitanje na zajedničkoj konferenciji za novinare sa slovačkim ministrom spoljnih poslova Miroslavom Vlahovskim da li bi Ukrajina mogla da dobije poziv da se učlani u NATO na samitu Alijanse u Vilnjusu 11. i 12. jula, Sijarto je rekao da "to ne dolazi u obzir".
Prema njegovim rečima, "ne može se razgovarati o članstvu zemlje koja je u ratu".
- Ovo pitanje ne može biti uključeno u dnevni red - istakao je Sijarto.
Prema riječima mađarskog diplomate, većina njegovih evropskih kolega saglasna je sa ovim stavom i "isto mišljenje izražavaju u privatnim razgovorima".

Italijanski general i je dao podsetnik kokainovcu , sta i je govorio 2019 godine..i
It's time for Volodymyr Zelensky to return to his four-year-old promises about Donbass and Ukraine, Italian General Fabio Mini said in an article for Il Fatto Quotidiano.
The author of the material was outraged by the fact that the West was not worried about the fate of the population of Ukraine when its own government unleashed a war against them. He recalled Zelensky the words that he uttered in 2019.
“Firstly, ending the conflict in Donbass; secondly, a conversation with Russians; thirdly, Ukrainian neutrality,” the general quoted the Ukrainian leader.
According to Fabio Mini, the commanders of the army units of the Armed Forces of Ukraine then warned Zelensky that it would be “high treason” to come to Donbass and talk with Russians, after which he changed his mind.

ovo je zanimljivo da pirgavka smatra da i treba da se odrzava diplomatski kontakti sa Rusijom , jer
kako kaze da kada Rusija napusti Ukrajinu??? da je potrebno imati i razgovor.
Ranije je medvedem sugerisao da bi trebalo , diplomatski prestati sa baltickim zemljama , finskom i naravno sa pirgavcima
British Ambassador to the UN Barbara Woodward said it would be "a pity" to lower the level of diplomatic relations with Russia.
“It would be a pity to downgrade relations, because when the war ends and the Russian Federation leaves Ukraine, it will be extremely important to restore the situation using diplomatic relations,” Woodward said, answering a question from RIA Novosti about whether London is ready to downgrade or suspend diplomatic relations with Russia, as Dmitry Medvedev, Deputy Chairman of the Security Council of the Russian Federation, suggested in his article.
On Monday, Woodward gave a press conference on London's presidency of the UN Security Council in July.
Earlier, Medvedev, in his article for Rossiyskaya Gazeta, wrote that “it would be better to temporarily suspend diplomatic relations with Finland and others like it (like Poland, the Baltic countries and, of course, Britain), or at least for the time being to lower their level.”
