Pole-21 increasingly asserted its place in the Russian military. (Source: Top War) Shield against potential hazards Pole-21 is resistant to high-precision weaponry and other enemy systems using the satellite navigation system. The mission of this combination is to jam and suppress signals from the navigation satellites. In addition, they can accurately detect the enemy’s coordinates, missiles, bombs, aircraft … and handle other assigned combat missions. The weapons complex consists of R-340RP signal reception poles, including the control equipment and interfering antennas, capable of suppressing radio signals at a minimum range of 25km. The combination is capable of suppressing signals from all current navigation systems. The R-340RP antenna stations are mounted on cell towers that are installed at a suitable height or mounted on car chassis with a basin module. Compatibility with various power sources guaranteed. Each pole consumes up to 600 watts of power. Communication between the composite’s components can be maintained through the radio. Therefore, during the installation process it is possible to use GSM antenna as a backup. Pole-21 can be deployed and installed in large numbers over a large area, depending on topography and topography. In favorable areas, a “dome” consisting of 100 antenna columns allows coverage over 22,500 square kilometers. Distribution of Pole-21 In August 2016, Russian media reported that the Pole-21 system was officially preparing to be put into service for the military. In November 2019, the Russian Ministry of Defense announced that Pole-21 had transferred to an electronic warfare unit from the Central Military Zone in charge. Shortly thereafter, in early December 2019, some sources said that the Ministry of Defense continued to deploy the Pole-21 system at base 201 of the armed forces in Tajikistan and operated in alarm mode. In January 2021, the Ministry of Defense announced that by the end of this year, the Central Military Region units would receive 10 additional Pole-21 complexes. These products will be delivered to deployment units in Urals and Siberia. Moreover, Russia also recently officially announced the Pole-21’s presence at the Tartus base in Syria. This system, which works in conjunction with other modern air defense systems, is used to counter potential raids and to prevent potential adversary attacks. In addition, experts from the 49th Army of the Southern Military Region used the Pole-21 combination in training activities. It is known that in the exercise, “Pole-21” mainly confronted the enemy drones. Future protection system The Russian Army Base 201 is the first unit to use this combination. In early January 2020, the system officially worked covering residential areas, armory and locations of important Russian air defense complexes. Through recorded reports, the use of Pole-21 combination in different exercises has brought many positive signals. These products are used independently, or in combination with other electronic warfare systems, completely convenient and effective. In October of last year, Central Military Region troops combined with the “Zhitel” jamming station succeeded in destroying UAV communications. In Tartus, with support from Pole-21, the Ratnik complex. -Kupol suppresses the signals for navigation and control channels. The recent drills in the Southern Military Region demonstrate the Pole-21 system’s capabilities to operate in the reconnaissance and attack lines of the combined armed army. Electronic warfare units act as part of the battalion-level tactical group and protect them from reconnaissance drones. The transfer of the Pole-21M serial electronic warfare system to the military has only started in mid-2019 and was received by subdivisions. It is known that the production and supply of these equipment will continue to develop, of which the Central Military Zone will receive 10 new complexes this year. In the past, the Pole-21 complex has confirmed their ability in trials, as well as their potential in the framework of various scale exercises. In particular its ability to interrupt enemy navigation, interrupt mission execution and ensure the protection of its facilities has been repeatedly demonstrated. It is easy to see that the Pole-21 unit, with all its proven advantages, deserves to be an excellent external signal suppression system, which completes the task perfectly. thanks to its high technical characteristics and mobility. In addition, the principle of preventing satellite positioning is consistent with the current development trends of the military and weapons. (According to Top War)

With modern air defense systems, dealing with such UAVs is both extremely difficult and very expensive. REX-1 electromagnetic gun. (Source: Top War) To deal with small pulse and reconnaissance UAVs, Russia is developing specialized equipment such as the Kalashnikov Military Technical Corporation’s REX-series electric guns or special anti-air missiles being developed by engineers of the Russian Nuclear Center. In 2015, Kalashnikov Military Engineering Corporation acquired a stake in drone maker ZALA Aero to develop unmanned technology and anti-UAV weapons. This group is working to develop electronic warfare systems focusing on fighting against modern UAVs. Among them are two models of non-lethal weapons REX-1 and REX-2 that appeared at military technical exhibitions. REX-1 electromagnetic gun In terms of parameters and weight, the REX-1 electromagnetic gun is compact in size, comparable to modern automatic weapons. According to the manufacturer, the weight of REX-1 reaches 4.5 kg, built-in battery backup, ensures 3 hours operation. The main mission of the REX-1 is to protect critical facilities and enclosed areas from intrusive drone vehicles. This is especially important because modern air defense systems are not always guaranteed to destroy UAVs, and detecting small drones using conventional electronic reconnaissance means is difficult. towel. According to the Kalashnikov Group, REX-1 can interfere with the signals of the US GPS satellite navigation system, the BeiDou of China, the European Galileo or the Russian GLONASS within a radius of 5 km. In addition, at a distance of 1 km, REX-1 can block LTE, 3G, GSM signals, interfering with the running frequencies: 900 Mhz, 2.4 GHz, 5.2-5.8 GHz. Thanks to these capabilities, the REX-1 is able to neutralize enemy drones without causing physical harm. Besides, controlling the REX-1 is quite simple. In addition, the REX-1 is equipped with additional lights, target indicators and various points of view. REX-2 electromagnetic gun In the framework of the Army International Forum 2019, the new version REX-2 launched has been rated by many military experts as the world’s most compact anti-drone gun. The main advantage of the REX-2 is its compact size and light weight. If the original design REX-1 weighed approximately 4.2-4.5 kg, the weight of the non-lethal REX-2 was only about 3 kg and the length should not exceed 500mm. According to the developers, the REX-2 is designed to disable all types of UAVs, including optical devices used on the ground or underwater. The lighter and smaller version of this device effectively overwhelms the signal of the satellite navigation systems within a radius of 2km. The REX-2 works by suppressing radio and satellite navigation signals – technology used in the operation of most modern UAVs. The REX-2 developer wants this new weapon to be able to counter a wide variety of targets since their components are interchangeable, as well as tailored to suit missions. Specifically. Antidrone jet rockets Last March, the sheet Izvestia reported that the experts of the Russian Federal Nuclear Center are developing high-speed anti-drone equipment with jet missiles (antidrone). The antidrone missile consists of the missile hull, a target guidance system and a net-trap container (nets with dumbbells in corners). Missiles carrying “mesh bullets” shoot directly to the enemy’s drones, then open the net, ensuring to capture and disable the UAV. However, experts say, similar UAV trap projects in Russia are not effective enough to intercept high-speed vehicles when performing complex aerial maneuvers. According to the news agency RIA Novosti In order to intercept UAVs with mesh bullets, the antidrone missiles need to be adjusted to launch a network of traps at a predetermined rate. The process above will take steps and be difficult as high-speed targets can quickly get out of range of the device. (According to Top War)

Samsung has an unexpected move Photo: @Pixabay. It seems that the company has realized that “quantity is not equal to quality” should decide to slow down with the megapixel race. Recently, famous leaker Ice Universe announced that Samsung now intends to return to another “rationality”, and will stop blindly chasing big numbers. Clearly, we’re talking about the fact that the company is recklessly stopping the megapixel-resolution race. “I heard some news that Samsung smartphones are actively changing the camera sensor. It will return to reasonable, instead of blindly large numbers,” Ice Universe stated. In fact, Samsung admits that quality is not at the megapixel count. Priorities will be the tradeoff between the size and resolution of each pixel. And the first result of this approach that we saw in the Samsung ISOCELL GN2 sensor; in which the company offers a record large sensor size of 1 / 1.12 inch; No frills on the megapixel count with just 50 megapixels. Photo: @Pixabay. After the shocking information above, it is still unclear what the fate of the 200 megapixel sensor on a smartphone with up to 6 cameras, with a dual selfie camera and a homegrown chip will be. On the other hand, there are also rumors that, Samsung has set itself a goal of delivering an insane 600MP sensor. The 600 MP sensor that Samsung has developed seems to have a pixel density of 0.8 µm and a size of about 1 / 0.57 inches. So the result is more work the company has to deal with as the sensor will take up 12% of the smartphone’s area, and it will also result in a 22mm protrusion. The Galaxy Note20 is 8.3 mm thick, which means the 22 mm camera bump will make the phone look too out of date. Photo: @Pixabay. With these changing priorities, it remains to be seen whether this will affect the development of the aforementioned sensors in the near term. In July 2019, CEO of Zeiss, Mr. Michael Kaschke made the point that, the race of “dots” on smartphones is meaningless. Because according to him, “the sensor on a smartphone is so small that mobile photography will never be able to overcome some of the limits such as processing speed, signal ratio, noise … and increasing the number of” dots. “Not the right solution in this regard, even a stumbling block”. In fact, the higher the resolution of the sensor, the smaller the individual pixels, and the more difficult it is to illuminate them entirely. The result is that the image will be noisy, which the algorithms must try to limit to reduce this situation. For Kaschke, a 40 MP sensor is more than enough for a smartphone, let alone 64 MP. Therefore, increasing the number of “dots” will not bring any benefit. Photo: @Pixabay. However, it is undeniable that the introduction of the smartphone is one of the most remarkable strides in the history of the technology industry. It is not simply a pocket communication device but gradually meets all human information needs. Photography is also an equally important part. It creates many new needs such as sharing daily photos, taking selfies, video calling. Smartphone photography is gradually asserting itself with a steady decline in sales of travel cameras. According to data from GfK, Canon’s travel camera revenue is down 2% per year due to the replacement of smartphones.

Optimizing mass noise is a challenging problem in phono cable design. Nordost Odin 2 Tonearm Cable + solves this problem with 2 solutions. First, Nordost’s tonearm wire isolates the mass signal completely. When necessary, users can choose to mass-connect the chassis of the charcoal tray and the phono preamp to create a link with extremely low noise between the two devices. The second way, Odin 2 Tonearm Cable + uses 2 ground wire segments (detachable, equipped with 2 Dual Phono-Filament and TSC technologies) directly connected to the armor layer of the main tonearm wire, eliminating socks also interference in signal transmission. Similar to Nordost’s Supreme Reference cable line, Odin 2 Tonearm Cable + has a calculated length to minimize microphonic vibration noise. The company’s top tonearm wire uses HOLO: PLUG jacks with 4 options, straight DIN, 90-degree DIN, RCA and XLR. Odin 2 Tonearrm Cable + is manufactured by hand in the US, which is essential in making signal cables that require extreme precision. Cable Nordost Odin 2 Tonearm Cable + has a reference price of $ 12,999 / 1.2m and $ 15,999 / 2m. Nordost brand’s official distributor:

Japan and Germany hold their first Diplomatic and Defense Strategic Dialogue (Dialogue 2+2) online, April 13. (Source: AP)

According to the sheet Nikkei (Japan), on April 13, Japan held its first Diplomatic and Defense Strategic Dialogue (Dialogue 2+2) with Germany online, a framework similar to that of other important European partners, Britain and France.

Clearly, Prime Minister Suga Yoshihide’s administration is increasingly urging key European partners to increase their intervention in the Indo-Pacific region, especially amid certain rifts in China’s relations with Europe recently regarding human rights democracy.

Attending the dialogue on the Japanese side were Foreign Minister Toshimitsu Motegi and Defense Minister Nobuo Kishi, while on the German side were Foreign Minister Heiko Maas and Defense Minister Annegret Kramp-Karrenbauer.

At the dialogue, Japanese Foreign Minister Motegi criticized China for saying that “unilateral actions to change the status quo by force have lost the premises of peace and prosperity for the international community.”

Meanwhile, Secretary Maas stated that “security cooperation is extremely important in the context of various threats in the Indo-Pacific region.”

The German side said it would send a destroyer to the Indo-Pacific region next summer and planned joint training between Japan’s Maritime Defense Force and the German Navy.

It is unusual for a country without territory in the Asia-Pacific to send warships to the region, but it is also the first time germany has shown strong colours on security issues.

This Japan-Germany 2+2 Strategic Dialogue is an example that Germany is ready to participate in the race for sovereignty in the Indo-Pacific region.

Basically the strategy of the Biden administration and its allies is to bring together a siege that restrains China, including European countries. It’s also a sign that the U.S. feels the difficulty of unilateral confrontation and arms race with China.

Other European countries are already aware of the threat from China.

Britain identified China as the biggest national threat to economic security, identified in a new security and diplomatic strategy announced in March.

Britain has left the European Union (EU) and does not want China to lead Asia, which is seen as its promising market. London has also expressed its intention to join the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), an agreement that plays a role in creating a siege on China.

In the current context, the similarities between the UK and Japan are to promote the free trade system in the Indo-Pacific region, while curbing China’s expansion at sea.

Among European countries, Britain has pledged to send the aircraft carrier HMS Queen Elizabeth and France will send a nuclear-powered attack submarine to the Indo-Pacific region.

According to Professor Yuichi Morii of the University of Tokyo, recent moves by Britain, France and Germany have sent a message of cooperation to Japan as countries that share a common view of values.

German Chancellor Angela Merkel once said China was a “systemal competitor” with political differences. However, China is also a huge market with a size of 1.4 billion people and is an important trading partner of Germany.

On April 7, during a phone call with Chinese President Xi Jinping, Ms Merkel also stressed the importance of dialogue.

As European relations with China tend to cool and the region faces serious economic impact from the Covid-19 epidemic, the U.S. and Japan should work to promote diplomatic activities with European countries, in order to support maintaining a tough stance on security.
