China's satellite navigation industry valued at $80 billion in 2024
Ammon News - By the end of last year, the overall value of satellite-enabled navigation and positioning services in China reached about 576 billion yuan ($80 billion), a 7.39 percent year-on-year increase, according to an industry white paper released on Sunday. The 2025 White Paper on the Development of China's Satellite Navigation and Positioning Industries, compiled by the Global Navigation Satellite System and Location-Based Services Association of China, said the combined output of chips, equipment, software, data and infrastructure totaled 170 billion yuan, up 5.46 percent from the previous year. In 2024, about 410 million terminal devices equipped with satellite-based navigation and positioning functions were sold in China, including roughly 294 million smartphones and more than 20 million vehicle-mounted devices. By the end of the year, over 2 billion devices — such as smartphones and computers — on the Chinese mainland were capable of using China's Beidou navigation and positioning service. Nearly 1 million people are employed at about 20,000 domestic institutes and companies engaged in Beidou and other satellite-based navigation and positioning services, according to the white paper. Beidou is one of China's largest civilian satellite systems and one of four global navigation networks, along with the United States' GPS, Russia's GLONASS and the European Union's Galileo. Since 2000, a total of 64 Beidou satellites have been launched aboard 47 Long March 3-series rockets from the Xichang Satellite Launch Center in Sichuan province. The system was declared complete in July 2020 and has been providing full-scale global services since then.

China's BeiDou, A GPS Rival, Powers Over 1 Trillion Daily Location Checks
Quick Reads Summary is AI generated, newsroom reviewed. China's BeiDou satellite system processes over 1 trillion location checks daily, powering its tech-driven economy and supporting 288 million smartphones. Competing with GPS and others, it serves over 120 countries and generated 575.8 billion yuan in 2024. China's BeiDou satellite system is now powering billions of location checks daily and backing a growing chunk of the country's tech-driven economy, new data shows. Named after the seven northern stars used for ancient navigation, the homegrown BeiDou network is compatible with 288 million smartphones across China, mainly from domestic brands like Huawei and Xiaomi. It processes more than 1 trillion location checks every day. BeiDou was designed to compete with the US GPS (Global Positioning System), Russia's GLONASS, and the European Union's Galileo navigation systems. Launched 30 years ago with its first satellite, BeiDou has grown into a major player in global navigation. In 2024, it generated an economic output of 575.8 billion yuan (about Rs 6.65 lakh crore), marking a 7.39 per cent increase over the previous year, the GNSS and LBS Association of China reported on Sunday. Started in the 1990s, the BeiDou system now powers everything from military operations and drones to smartphone navigation and disaster response. It includes around 30 satellites, offering global coverage since 2018. The network is already being used in over 120 countries, including Pakistan and Thailand. To meet growing demand, BeiDou is now compatible not just with phones and car systems but also with wearables, drones, electric bikes, and even robots, according to state-run Xinhua News Agency. "America's GPS in China is now either not supported on some domestically made devices or deliberately not used due to security reasons, especially when a government agency, state-owned enterprise or military unit needs navigation services or extra-precise mapping," said an academic at Zhejiang Sci-Tech University, as per The South China Morning Post. BeiDou is also upgrading its coverage and improving signal speed, while GPS faces tighter controls in China due to national security concerns. Leading apps like Baidu Maps and Amap said they relied on BeiDou to guide users through a combined 4 billion km of travel daily. "Foreign companies face certain restrictions on collecting high-precision mapping data in China, but many smartphones like iPhones support both GPS and BeiDou, automatically selecting the best signal," he added.

All about Turkish Songar drones used by Pakistan to attack India, It is designed for both..., can fly up to 3000 meters, has ability to...
India has said that the drones used by Pakistan in its failed attempt to target 36 military and civilian sites between the night of May 8 and the morning of May 9 were likely Turkish-made Songar models. During a press briefing on Friday, Colonel Sofiya Qureshi and Wing Commander Vyomika Singh shared that early investigations into the drone wreckage pointed to the use of Songar drones, built by Turkey's defence company Asisguard. A detailed forensic analysis is currently underway. The Songar drone is Turkey's first locally developed armed drone. It was unveiled in April 2019 and officially entered service with the Turkish Armed Forces in early 2020 after extensive trials. Weighing up to 45 kilograms at takeoff, the drone can operate for around 35 minutes when not carrying weapons. It can fly up to 3,000 meters above sea level and about 300 meters above the ground. With a 5-kilometer operational range, Songar drones are designed for both day and night missions. One of the key features of the drone is its ability to live-stream footage to ground operators. It is equipped with both a surveillance camera and a gun-mounted camera, allowing it to track targets and potentially engage them during flight. The Songar supports both manual and autonomous flight modes and has a built-in safety system that sends it back to its launch point if communication with the controller is lost. It relies on GPS and Russia's GLONASS for navigation. Songar Drones: Weapons and capabilities explained The Songar drone system, developed by Turkey's Asisguard, comes in several versions depending on the kind of weapon it carries. According to the company's official website, there are five main models: Assault Rifle Variant (5.56×45 mm) Twin Grenade Launcher (2×40 mm) Drum Grenade Launcher (6×40 mm) Mortar Gripper (3×81 mm) Tear/Smoke Grenade Launcher (8× grenades) All versions are equipped with strict safety protocols that prevent them from firing until the operator gives the go-ahead. The assault rifle version uses standard NATO 5.56×45 mm bullets and includes a recoil-absorbing system that helps keep the drone stable while shooting. The basic grenade launcher model can shoot two grenades up to 400–450 meters. For higher volume attacks, there's the drum version that fires six grenades at the same range. Meanwhile, the tear gas or smoke version can launch eight grenades, which descend in a controlled way to ensure accurate targeting. These are designed more for crowd control or disruption rather than lethal impact. How Songar drones are used in battle These drones are built to work alongside troops or other drones in coordinated missions. They're useful in many kinds of operations on land, at sea, or during special missions where stealth is key. Thanks to their small size and quiet operation, Songar drones can be used to surprise the enemy without revealing where they're coming from. Apart from attacking, they also act as scouts, sending live video feeds back to commanders to help track enemy movements and plan tactics in real time.

Masterstroke by PM Modi as India plans to jam signals of Pakistani planes and fighter jets
New Delhi: The relationship between India and Pakistan is witnessing a new low after the Pahalgam terrorist attack. With the possibility of a military response from India, Pakistan is on high alert. In this situation, India has dealt a significant blow to Pakistan's navigation system. According to the reports, India has deployed advanced jamming systems to disrupt the signals of global navigation satellite systems used by Pakistani military aircraft. These systems have been stationed along the western border. India's jamming systems are expected to interfere with satellite-based navigation platforms including GPS, GLONASS, and BeiDou, which are reportedly used by Pakistani Air Force aircraft. Before this, India had decided to close its airspace to Pakistani aircraft. India's airspace will remain closed for Pakistan from April 30 to May 23. It is important to note that a jamming system is a part of electronic warfare, designed to disrupt radio frequency signals. It often sends false signals to confuse enemy equipment. These systems deployed by India are high-frequency jamming systems specifically designed to target GNSS signals used in military operations. After Pakistan violated the ceasefire, activity has intensified in several sectors along the Line of Control (LoC). The Indian Army is closely monitoring the situation and has issued an operational alert in border areas. Following the terrorist attack in Pahalgam, the Indian government has moved into action mode and is taking strict measures against Pakistan. Meanwhile, tensions continue to rise along the LoC. Pakistan has been repeatedly violating the ceasefire for the past seven days, firing with light weapons throughout the night. However, on Wednesday, Pakistan escalated the situation further by opening fire on the international border in the Paragwal sector of Jammu. According to reports, until Tuesday morning, the Pakistani army was only violating the ceasefire along the Line of Control. But now, as of Wednesday night, it has also opened fire on the international border in Jammu's Paragwal sector, further deteriorating the situation.
