➀ The US Air Traffic Control Association criticized the slow progress in resolving air traffic control system issues, highlighting the lack of a comprehensive plan since 1957;
➁ Despite congressional acts (1957 Airways Modernization Act and 1958 Federal Aviation Act) and allocated funds, no effective system plan was developed over three years;
➂ The root issue stems from failure to clearly define the problem, hindering solutions despite extensive expert analysis.
➀ United Airlines disabled Starlink Wi-Fi on Embraer E175 regional jets due to reported VHF radio interference with pilot communications;
➀ About two dozen aircraft affected, with fixes already applied to one-third of the fleet during scheduled maintenance without flight cancellations;
➂ United confirms the issue is temporary and plans to resume Starlink rollout across its entire fleet within weeks.
➀ Inertial Labs, a VIAVI Solutions Inc. company, has launched the M-AJ-QUATRO, an advanced anti-jamming antenna system designed to ensure Assured Positioning, Navigation, and Timing (A-PNT) in GPS/GNSS-challenged environments. This system supports military and commercial aviation applications.
➁ The M-AJ-QUATRO features adaptive digital nulling with over 34dB+ interference suppression (export-free version) and over 45dB+ suppression (export-controlled version), along with dual FPGA-based encryption and anti-spoofing technology to secure signal integrity.
➂ The antenna supports GPS, GLONASS, GALILEO, BEIDOU, and QZSS, ensuring reliable global coverage across L1, L2, and L5 GNSS bands, and is built to meet MIL-STD-810G and MIL-STD-461F standards.
➀ Researchers at the Karlsruhe Institute of Technology (KIT) have demonstrated the production of climate-friendly fuels like kerosene using Power-to-Liquid (P2L) methods from CO₂, water, and green electricity.
➁ In the Kopernikus P2X project, an innovative and highly efficient co-electrolysis process has been coupled with fuel synthesis for the first time at an industrial scale of 220 kilowatts.
➂ The Federal Ministry of Education and Research (BMBF) is funding this project.
