For the purpose of expanding photo reconnaissance capabilities to ensure combat operations, the US National Mapping and Photographic Reconnaissance Service is authorized to use images of the territory of Afghanistan taken by the commercial Ikones satellite, with high resolution. 1m resolution. The US military also has the right to use information received from the satellite system to explore the earth’s natural resources. These are Landsat-7, Terra, Orview satellites. Information from these satellites is used to establish, supplement and clarify topographic maps, to facilitate the assessment of the situation in the area of ​​combat operations. The figure shows the NAVSTAR navigation satellite system. Photo: britannica In this war, the United States decided to extend the use of the experimental satellite for opto-electronic imaging of the earth’s surface EO-1 belonging to the National Aeronautics and Space Administration (NASA) for the purpose of ensuring the integrity of the satellite. better for the US military. Thanks to this satellite, the US military has received images of the earth’s surface position with a resolution of 30m, allowing it to be used to assess the damage of the target, on the basis of comparing the multispectral images obtained to take pictures before and after taking the blows and to calm down on the need for repeat attacks. For radio reconnaissance satellites, the US uses 2 Acvakaid satellites (Magnum and Mentor types). These satellites allow the reception of radio communications, relay communications, convection, signals from satellites, signals of ballistic missiles, aircraft and vehicle control signals. unmanned flight. It is said that the Taliban use very modern means of mobile satellite communication. However, the American radio reconnaissance satellite allows to capture the communications between the Taliban commanders, to detect in time the location of the troops and their plans. Military communication satellites work with the greatest intensity, but only guarantee 40-60% of the requirements of the forces participating in the campaign. In the composition of this satellite cluster, there are 6 satellites of the DSCS strategic communication system, 3 satellites connected to the Mistar tactical and strategic communication network, 2 UFO-type satellites of the tactical-operational communication system. of the navy, air force and army, six satellites of the SDS transmission system. In addition, the US also uses satellites belonging to NASA systems to monitor and transmit TDSS information. Due to the sudden increase in the information traffic required to secure the operation, the United States had to make maximum use of space communication systems (compared to Operation Desert Storm, the traffic of information delivery increased by 7 times). Especially the Iridium mobile satellite communication system with 66 satellites operating in low orbit. This system ensures that the US military groups have enough communication channels connecting to the US Department of Defense’s digital information network (DISN) and ensures the communication system of the US state executive agencies, ensuring for the national telephone system and the Internet. The NAVSTAR navigation satellite system includes 24 satellites that ensure real-time navigation for US forces. The shortening of the adjustment time between satellites of the NAVSTAR system by the test measurement complexes of the US Air Force allows to improve the accuracy and determine the target coordinates for the use of technological weapons. high. In planning and conducting air strikes and missile strikes, the US military places particular emphasis on using information received from the satellites of the National Environmental Monitoring System (NPOESS). This system is used for weather forecasting, setting up global and regional meteorological maps for a period of 1 day to 2 weeks, allowing selection of information on cloud status, atmospheric pressure, etc. atmosphere and other parameters of near-Earth space. Meteorological satellites Block-5D2-8 and Block-5D3-1 are used with the highest intensity. The improvement of the operational efficiency of the NPOESS system allows to fully guarantee the US military units with meteorological information. In particular, the forecast of changes in solar activity has provided the ability to promptly correct the functions of communication, reconnaissance and navigation satellites, contributing to improving the efficiency of attacks and the detection of satellites. command the forces. To secure meteorological forecasts for navies, NASA’s Quicksat satellites are used to determine wind speed and direction over the ocean’s surface. Thus, during the war in Afghanistan, US satellite systems were used with high efficiency. At the same time, it also revealed some disadvantages, such as the lack of radar and opto-electronic reconnaissance satellites to timely orient the commander to use tactical forces. As a result, in some cases, commanders did not receive timely reconnaissance information. In addition, the satellite’s unobservable cycle over the combat area disrupted the monitoring of the movements of Taliban forces and vehicles.

With headquarters in London, UK, the OneWeb company intends to deploy a total of more than 650 satellites in the lower orbit of the Earth, in order to provide users on the ground with high-speed Internet 24 hours a day. day through contact satellites. The company is also competing with billionaires Elon Musk and Jeff Bezos in the race to cover high-speed internet via satellite to anywhere in the world, especially in remote areas. This is the third time the Russian side has launched the OneWeb satellite beam into Earth orbit after the previous two missions took place in December 2020 and March respectively at Vostochny space airport with 36 satellites per launch. The first six satellites of OneWeb were launched from the Guiana launch site in France in February 2019, and last year, the company launched 68 more satellites from Baikonur launch site, Kazakhstan.

However, a Huawei PR officer told the Global Times on Saturday that he has not received such information. China Mobile declined to answer the Global Times when asked. Ma Jihua, a senior analyst in the tech industry in Beijing, told the Global Times that the move to use satellites is natural as Huawei pushes up the layout of 6G networks, 50 times faster than 5G. Compared to building 5G networks that rely on base stations to transmit signals, 6G networks transmit higher frequencies, needing to use satellites for communication instead of base stations where there will be low penetration capacity, Ma explain. Illustration. Huawei’s rotating chairman, Xu Zhijun, announced at Huawei’s global analysts conference earlier this month that the Chinese tech giant will launch its 6G network by 2030 at the same time soon. Release of 6G white paper to explain what is 6G industry. In fact, in 2019, Huawei proposed launching more than 10,000 small satellites to provide 6G services worldwide, during the global 6G summit. China has made the biggest 5G footprint worldwide and is likely to go further in 6G development with efforts from giant Huawei, which has 5G technology outperformed. rivals and also leads in research and development 6G despite the US causing difficulties. According to Ma Jihua, the potential of 6G technologies is something no government or company can ignore despite the fact that it is still in the early stages of research and development. Satellite communication has shown increasing importance since last year with the proposal of new infrastructure. Ma Jihua also noted: “We need to know how to communicate in a satellite constellation as the country pushes forward with technology development along with Huawei’s new 6G satellite moves even though both use satellites.” China’s satellite constellation, such as the current projects in which Hongyun and Hongyan have been involved, aims to make online access available to residents and businesses in remote and remote areas in China. While the 6G satellite is used more widely for testing and data availability in popular metropolitan areas, Ma added. It is known that at the end of last year, China launched the world’s first 6G test satellite from the Taiyuan Satellite Launch Center in Shanxi Province, North China, marking a breakthrough in public discovery. terahertz space communication technology of China.

SpaceX denied claims that the Starlink and OneWeb satellites almost collided In a filing submitted to the US Federal Communications Commission (FCC) after a meeting between representatives of SpaceX, OneWeb and FCC, SpaceX said that, in fact, the probability of a collision never exceeds the allowed threshold and the satellite will not be able to collide even if it is active. They have also corrected records regarding recent press releases regarding the physical coordination between SpaceX and OneWeb. Meeting between the parties took place the day after the flyer The Wall Street Journal published an article titled “Elon Musk’s satellite Internet project is too risky,” in which OneWeb made allegations that the Starlink satellites had approached other satellites alarmingly two. times in the past two years, including the last which took place on April 2, when a satellite Starlink Send a request to a OneWeb satellite to take collision avoidance measures. Sheet The Wall Street Journal quoted Chris McLaughlin, OneWeb’s director of legal and government relations, saying, “While working with OneWeb, SpaceX disabled the automated collision avoidance system supported by artificial intelligence (AI) to allow OneWeb to steer its satellite away from other satellites. It is unclear exactly why SpaceX disables the collision avoidance system when the Starlink satellite is within 57 meters from the opponent’s satellite. SpaceX has not yet commented on this issue. In a filing filed with the FCC on April 21, SpaceX said: “OneWeb recently made clear and inaccurate statements to the media about recent coordination. Specifically, Mr. McLaughlin of OneWeb told the newspaper Wall Street Journal that SpaceX has powered off the automatic satellite collision avoidance system. In reality, however, SpaceX and OneWeb have worked well together on a technical level. And OneWeb itself has asked SpaceX to temporarily turn off the AI ​​system to allow them to control the satellite as agreed by the parties. SpaceX’s automatic collision avoidance system has been and still works well at all times. According to SpaceX, OneWeb admitted wrongly and offered to withdraw its false statements during the meeting with SpaceX and FCC. SpaceX expressed its disappointment to the FCC that OneWeb officials chose to make public false information about the coordination’s plight. Successful coordination depends on trust and transparency among satellite operators. Also in the filing to the FCC, SpaceX confirmed that the possibility of collisions between satellites is very small. Other data also showed that “probability of collisions between satellites is below the permitted threshold and continues to decrease”. OneWeb launched satellite launch operations on April 3, and the satellites are eventually more than 1,000 meters apart. The probability of a collision happening is extremely small.
