Simply Explained Ep. 06: Airplanes and Starlink satellites are... constantly moving at high speeds. How do they stay connected? The key is tracking and switching. A Starlink antenna on top of the airplane sends a radio signal toward a satellite. As the airplane flies and the satellite moves, the antenna constantly adjusts where that signal points. It does this electronically, without physically turning, allowing it to keep tracking the satellite even when the airplane changes direction. Before that satellite moves out of range, the system automatically switches the connection to another satellite passing overhead. This is similar to how your phone switches between mobile towers as you travel. These switches happen throughout the flight, keeping your data flowing as different satellites come into view. And radio signals travel at the speed of light, far faster than either the airplane or the satellites. Their movement doesn’t outrun the signal; the system just needs to keep it aimed correctly and switch satellites at the right time.show more

🚨 A SATELLITE JUST REVEALED SOMETHING SHOCKING: GPS JAMMING... IS FAR MORE WIDESPREAD THAN ANYONE REALIZED. An experimental navigation satellite called Pulsar-0, flying just 500 km above Earth, has mapped GPS signal tampering from space for the first time and the scale surprised even the engineers who built it. As soon as the satellite passed over Europe and parts of the Middle East, its GPS receiver showed massive signal degradation. In the worst areas, signal strength dropped from a normal 40 decibels all the way down to just 10 decibels. Why this matters: • Ground-based jammers (used in conflicts like Ukraine and the Middle East) are now reaching all the way into low Earth orbit • Satellites like Starlink that rely on GPS for collision avoidance and positioning are being affected across a huge region from France to the borders of Pakistan • When GPS drops out, satellites can’t accurately point their antennas, maintain formation, or safely maneuver • This isn’t just a military problem it threatens the growing network of commercial satellites we increasingly depend on The deeper implication: We’ve long known that GPS signals on the ground can be jammed. What we didn’t fully appreciate is how far those jamming signals reach into space. Even satellites in low Earth orbit the backbone of global communications, Earth observation, and future mega-constellations are now operating in an increasingly hostile electromagnetic environment. Xona’s upcoming constellation aims to fix this with signals 100 times stronger than traditional GPS. But the bigger question remains: as more nations and groups weaponize jamming and spoofing, how resilient will our orbital infrastructure actually be? How concerned are you that GPS jamming is now reaching into space and affecting satellites? Follow for more frontier space technology and the hidden vulnerabilities of our orbital systems.show more

🇷🇺 Russia’s Starlink killers showcase new era of electronic... battlefield warfare Russia has ramped-up EW use to detect and jam Elon Musk’s Starlink terminals and satellites, Ukrainian media reports. 👉 Meet Russia’s key counter-Starlink systems: 🔸 Volna Kupol Garant Russia’s latest electronic warfare system reportedly uses a directed high-frequency radio beam to disrupt Starlink operations. Rather than damaging satellites orbiting roughly 500 kilometers above Earth, the system blinds them – cutting their ability to connect with ground terminals while they remain under attack. According to reports, Volna is a mobile system built around six trailers. Each carries a pair of steerable satellite dishes mounted on rotating platforms. A single battery is reportedly capable of denying Starlink coverage across an area of up to 20 sq km. Some analysts say the system was previously referenced under the designation Peresvet-M, although this has not been independently confirmed. Ukrainian sources claim Volna was first deployed during Russia's offensive in the Kharkov region in 2024. They also say its use has increased significantly in recent months. 🔸 Tobol The secretive Russian EW complex is reportedly used to disrupt signals from NATO-linked satellite networks, including GPS, Galileo, and Starlink. Reports claim that Tobol attacks satellite communications on both ends of the link – jamming downlinks from satellites to ground receivers and uplinks from Earth to orbit. Its power and range also allegedly allow it to create an electromagnetic "umbrella." 🔸 Kalinka The system is designed to hunt down satellite communications signals, including those transmitted by Starlink terminals at distances of up to 15 km. It can reportedly track and lock onto even Starshield – SpaceX’s hardened military variant of Starlink. Western media warns that while Tobol disrupts GPS signals on a broad scale, the Kalinka’s precision-targeting capabilities could pose a more direct threat to specific military operations. 🔸 Krasukha The Krasukha-S4 is designed to neutralize reconnaissance satellites, ground-based radar installations, and airborne surveillance systems. It does so by emitting powerful electronic jamming signals that disrupt key radar bands and other radio-frequency emissions. A standard Krasukha-S4 battery consists of two vehicles and has an operational range exceeding 300 kilometers. 🔸 Borshchevik The light mobile system is designed to detect and geolocate Starlink terminals within a 180-degree sector at ranges of up to 10 km, with a reported accuracy of five meters. Using direction-finding and biangulation algorithms, it can locate a target in less than three minutes at a single scanning position. The Borshchevik-2 airborne system hunts Starlink signals from the sky, with reported accuracy down to 0.4 m.show more

The Coromandel Express, traveling at a speed of 128Kmph,... had the proper authorization to proceed through the mainline, indicated by a green signal. However, someone tampered with the settings and diverted the train to the loop line, where a 6000 tonnes goods train was parked, even though the signal for the mainline remained green. This should not be possible, as India has a robust and world-renowned interlocking system in place. It appears to be a deliberate act of manipulation, suggesting culpable homicide. Such an act cannot be carried out by an individual with no significant influence; rather, it points towards the involvement of major players orchestrating this sabotage. An investigation is imperative to uncover the truth behind this incident.show more

Airbus Vertical Speed Indicators (VSI) primarily use a blended... "baro-inertial" system to display precise vertical speed, combining responsive inertial data from the Inertial Reference System (IRS) with long-term stable barometric pressure data. The inertial signal is used for dynamic maneuvers and air data for stability over time. This hybrid approach provides rapid responsiveness to pitch changes while maintaining accuracy, reducing errors inherent in using either system alone. Local airflow disruptions (such as turbulence or unsteady wind) can momentarily alter the static pressure, causing the VSI to show unsteadiness or oscillations even when the aircraft is on the ground.show more

WHY HAS INDIA SIGNED THE CONDOLENCE BOOK FOR KHAMENEI?... India’s decision to sign the condolence book for Ali Khamenei is being framed as a calibrated diplomatic signal rather than a political endorsement. FS Misri signed on behalf of the government to acknowledge protocol and maintain official channels with Iran, an important regional partner for India. The government describes it as a "graded response, an official level participation, not a political statement of mourning." By keeping the gesture bureaucratic and low key, New Delhi signals respect for diplomatic norms while avoiding a public position on the killing or the wider conflict involving Israel and the United States.show more

SOMEONE FROM TOKYO IS MAPPING BIRD LANGUAGE INTO REAL... DATA PATTERNS AND THE VISUALIZATION LOOKS LIKE A NEURAL NETWORK DREAMING Every bird sound - frequency, duration, amplitude and modulation - gets converted into 3D space coordinates and rendered as a cluster of colored points in real time through Deepen AI. A microphone captures the acoustic signal, FFT breaks it down into frequency components from 1 kHz to 8 kHz where most birds communicate, an ML model classifies the pattern and the mapped data hits a graph where each call type gets its own color and position in space. Birds have a vocal repertoire of 5 to 200+ unique signals depending on the species - and every signal carries different information about predators, food, territory and mates that humans simply can't hear. The same technology that decodes bird language detects anomalies in industrial machinery, cardiac rhythms and structural vibrations in buildings - he just trained it on nature first.show more

A simplified summary of my simulations of how drone... detector antenna placement affects signal reception, expressed as a conditional drone detection range for different frequencies - obtained roughly by normalizing the square root of total gain to a typical drone detection range. Red line - detection distance for antenna on the roof, blue line - for antenna under the windshield. Considering that the main sector from which drones can approach the vehicle is elevation from 0 to 30 degrees, and also that in reality the glass will attenuate the signal more strongly than in my simulations - mounting the drone detector antennas inside the vehicle significantly reduces its practical drone detection range, especially in the rear hemisphere.show more
