Unjammable quantum navigation tech gets first airborne test in UK

The GNSS relies on satellite constellations like the US Global Positioning System (GPS) and the EU’s Galileo to provide aircraft with Positioning, Navigation, and Timing (PNT) services. GPS jamming involves blocking the GNSS signal, while spoofing sends false information to disrupt flights. Although technical solutions have been developed, equipment suppliers and GNSS providers are engaged in a constant battle to provide resilience against attacks. GPS spoofing involves overriding legitimate GPS satellite signals to deceive receiver antennae and manipulate their navigation systems, in effect overriding legitimate GPS satellite signals. This can lead to incorrect positioning information, potentially causing aircraft to deviate from their intended routes or experience navigational failures. Strategically, spoofing can indicate that an aircraft is somewhere it is not, leading to a complete loss of navigational capability. #A320 #gps #spoofing

The marine industry has relied upon radar for years due to its robustness in reduced visibility. However, the modal shift towards autonomy now requires an additional level of sensing capability, which high-resolution, W-band radar can provide. Unlike traditional marine radar, Navtech Radars operate at a higher frequency of 76-77GHz which enables detection of objects as small as buoys, kayaks, and swimmers. This unlocks the ability for vessels to safely navigate congested waterways autonomously. #maritimeautonomy #radartechnology #safetyiseverything

Keep safe in demanding times! With the growing threat of GNSS jamming, spoofing and world conflicts, advanced technology for navigation and communication is vulnerable to disruption. That's where HF radio air to ground communication comes in. HF radio is reliable and stable, and it cannot be jammed. While some pilots may consider HF radio old school, it remains a crucial communication channel for safe and secure air travel. Stockholmradio (STORADIO) offers a reliable HF radio service with a quick and easy sign-up process, affordable rates, and 24/7 availability. Learn more about our services at www.storadio.aero. Understanding GNSS Jamming and Spoofing: GNSS jamming involves deliberate interference with satellite signals, disrupting communication between satellites and the aircraft's navigation system. Spoofing, on the other hand, involves transmitting false signals to deceive the GNSS receivers on board an aircraft. Both threats can compromise the integrity of the navigation system, jeopardizing the safety of flights. Stay informed and stay safe.

Interesting concept Even though most of today's aircraft rely heavily on GPS for navigation, the technology is far from infallible. That's why an alternative system is in the works, which may soon allow planes to navigate by "reading the fingerprint" of the terrain they're flying over.

https://lnkd.in/eiJhMJHz Good luck drone operators!! seems like you are GNSS immune in the CAA eyes. The internal CAA miscommunication chasm begs belief!! Be very very careful out there with GPS spoofed signals. Your Geo tools are useless in such an event. Stay safe out there

-This week, New Scientist magazine publishes an article about my photo series "VOR: Before the Satellite" VOR radio beacons are the main alternative to satellite systems for air navigation, as well as a backup system when satellite navigation is not available (solar storms, GPS interference, etc.) -Esta semana, la revista New Scientist publica un articulo sobre mi serie fotográfica "VOR: Before the Satellite" Los radiofaros VOR son la principal alternativa a los sistemas por satélite para la navegación aérea, así como un sistema de respaldo cuando la navegación por satélite no está disponible (tormentas solares, interferencias en GPS, etc)
