China is planning to launch a 300-satellite constellation of bullet-shaped satellites.
Chutian project: In a worrying development amid India-Pakistan tensions, China– Pakistan's 'all-weather-ally'– is planning to launch a constellation of bullet-shaped satellites into Very Low Earth Orbit (VLEO), aimed to build a surveillance network, which could potentially capture images of any location around the world. China to launch 300-satellite constellation
According to a report by the South China Morning Post, China's Chutian project, which aims to build a 300-satellite constellation for high-resolution remote sensing and communication, as well as surveillance, has passed key technology checks.
A year ago, China had launched the Chutian-001 from the Jiuquan Satellite Launch Centre by the China Aerospace Science and Industry Corp (CASIC), displayed core capabilities, including satellite system performance, high-resolution smart imaging and space environment monitoring, the report said. Chutian project to be deployed in 3 phases
Local local media sources, the report said the Chutian constellation will be deployed in three phases. In the first, initial technology and service verification stage, one experimental satellite was scheduled for launch last year to test operations in VLEO, after which a cluster of cluster of nine satellites will follow in 2025, to demonstrate real-time Earth observation capabilities, it said.
The Chutian project will enter its second phase from 2026-2030, focusing on large-scale deployment, during which CASIC aims to complete a 300-satellite network offering continuous global coverage with a range of imaging types – visible light, synthetic aperture radar, hyperspectral, and infrared – and response times as short as 15 minutes, the report said.
The third phase will be focused on integration and expansion, completing the full business system and pushing global response times to under 10 minutes, it added.
Zhang Chuan, project leader at CASIC, said the Chutian constellation will support a wide range of applications, from disaster response and watershed management to agriculture, forestry and fisheries, adding the satellite system is designed for high revisit rates, fast data processing, intelligent analysis and near-instant downlink capabilities. What are the potential military uses and why India's must remain alert?
According to experts, the Chutian constellation could be used as a global surveillance network, providing real-time target detection with precise satellite control and domestically developed technologies.
This could pose a potential security threat to China's rivals, especially India after the recent developments where Beijing openly supported Pakistan in its conflict with India.
Notably, the bullet-shaped body of the Chutian satellites is designed to reduce atmospheric drag, which is a major challenge for satellites operating below 300 km (186 miles), where air resistance is much higher. VLEO satellites typically orbit Earth at altitudes between 150 km and 300 km.

Sharp detection, no noise: China tests breakthrough radar technology

During the tests, the silent Cessna, using the new radar tech, identified ground targets with over 20 decibels greater clarity than traditional techniques New Delhi In a breakthrough that could reshape the future of military operations, Chinese scientists have developed a radar system that can detect moving targets without making a sound — even in the noisiest environments. The technology, developed by a team led by radar scientist Li Zhongyu, uses passive bistatic airborne radar and advanced signal processing to detect targets while remaining undetectable itself, reported South China Morning Post. The test Scientists in China tested a new type of radar technology using two small planes (Cessna-208 Caravans) flying in formation, separated by altitude. The one above sent out radar signals, and the other, flying silently below, gathered echoes without emitting any signals. They aimed to detect three vehicles moving far ahead over uneven terrain covered with dense vegetation and structures. For traditional radar systems, detection in such conditions is difficult because radar signals bounce all over the place in these environments. This creates clutter on radar screens, making it difficult to distinguish actual targets. Problems faced by traditional radar When two radar units operate separately, the reflected signals from targets don't stay aligned—they get spread out over different distances, known as range migration. This scattering causes the target's signal to blur, making it harder to detect clearly. Additionally, the Doppler effect, which helps identify moving objects, gets distorted as these frequency shifts spread over a wide range. This creates a lot of background noise that drowns out the actual signals from targets. Moreover, the unnecessary echoes change unpredictably depending on the distance, making it very difficult for conventional radar systems to filter them out effectively. How the new radar solves them The new approach uses three steps for clear detection: Motion correction: The researchers used techniques called Keystone transform and high-order compensation to gather the dispersed target signals into precise range spots. This focused energy made the targets easier to identify, aided by a process known as motion correction. Spectrum compression: This step refines blurred Doppler signals to sharpen the radar's ability to identify motion, improving target resolution. Space-time decoupling: Their breakthrough technology, called the 'space-time decoupling two-channel clutter cancellation method,' uses a special matrix (a math formula) to separate the clutter's non-linear knots. By aligning spatial frequencies to zero while preserving relative speed profiles, it allows perfect cancellation of environmental clutter between dual-channel echoes. During the tests, the silent Cessna identified ground targets with over 20 decibels greater clarity than traditional techniques, reported SCMP. The first tests for this novel tech were conducted five years ago. Military and strategic implications If and when implemented, the new radar technology could help military planes spot targets — vehicles, ships, missiles — at long range without being detected, even through clouds or darkness. Li's innovation also eliminates the exposure risks of low-probability-of-intercept (LPI) radars. LPI radars minimise the chance of being detected by operating at lower power levels or changing frequencies, but they still carry a risk of discovery. 'According to our knowledge, this is a world first,' Li claimed about the innovation.

Bad news for Elon Musk as China solves 'critical flaw' in his Hyperloop system, Chinese scientists say reduced...

China claims to have fixed a 'critical flaw' in Elon Musk's Hyperloop system. (File) China Maglev Train: Chinese scientists working on the country's futuristic high-speed maglev train project have claimed to have solve a 'critical flaw', in the Hyperloop concept proposed in a 2013 white paper by tech billionaire Elon Musk. A study published in China's peer-reviewed Journal of Railway Science and Engineering noted that the tiniest of imperfections, such as uneven coils or bridge deformations, could cause major turbulence in a Hyperloop system, turning the journey into a hellish ride, even in near-vacuum tunnels. Chinese engineers find method to reduce turbulence However, Chinese engineers working at the world's first full-scale test line in central China, claimed to have found a method to cut the turbulence intensity by nearly a half, reducing 'extremely severe bumps' to 'pronounced, but not unpleasant' levels, according to a report by the South China Morning Post (SCMP). As per the SCMP report, the engineers led by Zhao Ming from the maglev and electromagnetic propulsion division of state-owned China Aerospace Science and Industry Corporation (CASIC), revealed they employed supercomputer simulations and scaled-down prototype tests for the study. The researchers discovered that minor irregularities in the track and electromagnetic resonance, could trigger violent low-frequency vibrations in maglev cars travelling at cruising speeds of 1,000km/h (612mph). Their study used Sperling Index, a 1940s-era international metric for ride comfort, to show that oscillations amplified at specific speeds, reaching 'extremely unpleasant' levels of vibration at a peak speeds 400km/h (249mph). As per the study, the Sterling Index hit a 4.2 when the maglev cars reached the next peak of 600km/h (373mph), but the vibrations reduced to a 3.1 level on the index once the cars reached cruising speeds of 1,000km/h, the report said. China's Maglev train breaks speed record The Maglev system, first proposed in 1910 by American engineer Robert Goddard, gained traction in 2013 after Elon Musk wrote a white paper on the subject. The Maglev train, so named as it uses magnetic levitation (maglev) technology to reach unimaginable speeds, does not need wheels unlike traditional trains. Instead the wheels are replaced with magnets which lift the pods above the track, allowing them to glide effortlessly over the magnetized track. Late last year, China claimed that its Maglev train reached a record-breaking speeding 387mph (over 622 kmph), tumbling the record of Japan's MLX01 Maglev, currently the world's fastest train, which has a top speed of 361mph. Chinese engineers believe that their maglev system will be able to reach hypersonic speeds of over 1,243mph or over 2000 kmph — faster than the speed of sound and double the speed of a Boeing 737 aircraft, once commercial operations begin. If estimates are accurate the maglev system would significantly reduce travel times across China, reaching Wuhan to Beijing in just over 30 minutes, in contrast to the current high-speed train which takes four hours to complete the journey.

Chinese Company Cons Parents Out Of Rs 44 Lakh By Staging Fake Kids' Fashion Shows

A Chinese company has been fined 600,000 yuan (approximately Rs 72 lakh) by the government for running fake children's fashion shows and defrauding parents of 367,000 yuan (around Rs 44 lakh). According to the South China Morning Post, the Shanghai-based firm had been falsely promoting a series of fashion shows under the name "Paris Kids Fashion Week" since 2020. The company branded the events part of the globally recognised Paris Fashion Week, and used images of famous tourist spots in France, like The Louvre, on its website to lend credibility to the shows. The firm organised shows in major cities in China, as well as Paris and Toronto, SCMP reported. During one of its fashion weeks in Shanghai, it also promoted four events using the names of luxury brands like Dior, Gucci, Burberry and Fendi, and charged parents 6,000 yuan (approximately Rs 72,500) for a single appearance. It also set up a parent-child event for parents to appear together with their children. The elaborate scam came to light after Gucci's Shanghai office filed a complaint, prompting an investigation by the Shanghai Market Regulatory Bureau in 2023. During the investigation, officials found that the firm used Gucci's logos and knock-off emblems with the words Gucc101 and Gucc100. A member of the company's staff also admitted that the firm charged parents more than 10,000 yuan (around Rs 1.20 lakh) for each costume their children wore in the show. However, not all the clothes were authentic. The report stated that the company's owner, surnamed Huang, bought counterfeit clothes online. He argued that he only bought the fake clothes to take photos, and did not sell them. The authorities said the company's activities constituted trademark infringement. The firm made a total of 367,000 yuan from registration fees, which the investigation identified as improper gains. A procurator in Shanghai said the firm had been fined by market regulatory departments in other parts of China, but it did not correct its business. The bureau fined the company 600,000 yuan, which is approximately Rs 72 lakh.
