I found this interesting video on Tiktok on a new field that is being developed in the medical industry namely satellite surgeons. The video depicts on how doctors in China are utilizing the combination of satellites and robots obtain plus share data and at the same time perform operations on patients that are thousands of kilometers away. The two disruptive technologies can have a positive impact for patients and will enable doctors to assist other specialists in the medical field of performing operations almost anywhere across the world 🌎 #disruptivetechnologies #satellites #robots #medicalindustry #operations #medicaloperations #china

After reviewing hundreds of papers from the recent #IONGNSS conference, here are my top highlights for applications on planet Earth (leaving the Lunar stuff for now). Exciting times! 1. AI and Machine Learning Integration A dominant theme across many sessions was the integration of AI and machine learning (ML) into traditional GNSS technologies, such as: ·      Deep learning-assisted Kalman filtering for GNSS/IMU integration in denied environments. ·      AI-enhanced noise estimation for IMUs, improving inertial navigation accuracy. ·      ML for multipath error classification, enhancing GNSS accuracy in urban areas. 2. LEO Satellite-Based PNT Solutions There’s a growing emphasis on LEO-based PNT services as complementary or alternative solutions to traditional GNSS: ·      Starlink signals are being investigated for PNT, leveraging OFDM signals and pilot tones for navigation. ·      Xona Space Systems' PULSAR LEO PNT service promises sub-meter accuracy, faster Time-to-First-Fix, and enhanced security. 3. Augmentation and HAS services ·      Augmentation systems improve GNSS reliability and integrity and are pivotal in building trust in automated systems, particularly for safety-critical applications like aviation, or autonomous vehicles. ·      SBAS authentication standards strengthen protection against spoofing attacks ·      New results on JPL and Galileo High Accuracy Service (HAS) demonstrate improved availability, accuracy, and convergence times. 4. Robust Positioning in GNSS-Denied Environments ·      Radar-aided 5G positioning is a promising integration scheme for underground and indoor environments where GNSS signals are weak or unavailable. ·      Measurement-guided ray tracing offers a new method for estimating propagation paths, especially in complex indoor settings where multipath is an issue. ·      UWB-aided hybrid navigation is a promising approach for seamless transitions between outdoor environments (where GNSS works well) and indoor environments (where UWB excels). 5. Factor Graph Optimization (FGO) FGO is emerging as a powerful tool in GNSS/INS integration and RTK positioning. It has proven effective for multi-epoch ambiguity resolution in urban environments, showing promise for smartphone navigation and real-time applications. 6. Meta-Signal Processing Technology Meta-signal processing represents a novel approach that allows for enhanced processing of multiple signal types, which improves the resilience and accuracy of GNSS positioning. This is particularly promising for applications in urban canyons and areas with heavy interference, where traditional signal processing may fall short.

𝗜𝗖𝗘𝗬𝗘 𝗮𝗻𝗻𝗼𝘂𝗻𝗰𝗲𝘀 𝗻𝗲𝘄 𝗗𝘄𝗲𝗹𝗹 𝗣𝗿𝗲𝗰𝗶𝘀𝗲 𝗶𝗺𝗮𝗴𝗶𝗻𝗴 𝗺𝗼𝗱𝗲 𝗽𝗿𝗼𝘃𝗶𝗱𝗶𝗻𝗴 𝟮𝟱 𝗰𝗺 𝗿𝗲𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻 The industry’s highest fidelity 25 cm product will allow ICEYE’s customers to identify objects and features on the earth’s surface with far greater clarity than before ICEYE, the global provider of SAR satellite operations for Earth Observation and persistent monitoring, introduced Dwell Precise, a new imaging mode that adds advanced capability to ICEYE’s line of Dwell products and builds on the release of Dwell Fine in March 2024. Dwell Precise provides a 25-centimeter resolution and is based on the 1200 MHz radar bandwidth announced earlier this year. 1200 MHz is currently the maximum that commercial satellites are allowed to use. ICEYE’s Dwell Precise uniqueness comes from the combination of high-quality data with high resolution, and it will make a difference when the identification of smaller objects or targets is required, e.g. types of vehicles and types of military equipment, without the need for additional intelligence sources. As a SAR satellite orbits the Earth its radar signals focus on a specific area of the planet’s surface to create an image based on return data. Like other modes in the Dwell product line, Dwell Precise data are taken from a much more comprehensive range of angles, allowing it to spot objects through tree cover and foliage. ICEYE owns and operates the world’s largest constellation of SAR satellites. It first introduced Dwell mode in May 2023, and with the introduction of Dwell Fine in March 2024 and today’s launch of Dwell Precise, ICEYE further underlines its commitment to constant innovation in serving private and public sector organizations globally with the most advanced commercial Earth Observation capabilities and SAR satellite data.

🌍 Revolutionizing Navigation: GPS vs. Quantum Navigation 🛰️⚛️ Navigation has become an essential part of our daily lives, whether it's finding the fastest route to work or exploring uncharted territories. While GPS (Global Positioning System) has been our go-to technology, it comes with challenges like signal obstructions, interference, and dependency on satellites. Enter Quantum Navigation—a groundbreaking technology that leverages quantum sensors to determine precise positions without relying on external signals. This innovation could revolutionize navigation, making it possible to operate seamlessly in GPS-denied environments like deep oceans, dense forests, and even space missions. 🌌 🚀 Some fascinating milestones include the UK's successful testing of a Quantum Compass in an aircraft and the integration of quantum sensors with AI for next-generation navigation systems. But the big question remains: 👉 Can Quantum Navigation truly replace GPS, or will it complement it as an alternative? We'd love to hear your thoughts! 💬 Comment below with your ideas or insights.

Big news in aviation mental health research! The Aerospace Medical Association #MentalHealth #Research Working Group published consensus, research priorities related to mental health and global aviation! If you are an aviation researcher, aviation leader, or you’re a exploring an aviation mental health research project or thesis, I hope you’ll consider checking out this publication published in Nov 2024! https://lnkd.in/eT2EE4Ep TITLE: Aerospace Medical Association Proposed Research Priorities for Mental Health and Safety in Aviation INTRODUCTION: Aviation safety sensitive personnel (SSP) function in highly complex environments. SSP mental health is thought to support safety, efficiency, and overall health. Research is needed to identify how to optimize and screen mental health across aviation SSP, but no consensus exists on the research priorities that need to be met. METHODS: The Aerospace Medical Association established the Mental Health Research Subgroup within the Mental Health Working Group comprising 53 aviation and aerospace medicine professionals representing 9 countries. A five-round Delphi method was employed to generate research priorities. RESULTS: Research priorities were identified under the following six topic areas: 1) Safety and Performance; 2) Mental Health Initiatives, Education, and Peer Support Programs; 3) Clinical Care, Pharmacology, and Return to Duty; 4) Epidemiology and Natural History; 5) Screening, Monitoring, and Emerging Technology; and 6) Special Considerations and Underrepresented Populations [Aerospace Medical Association Mental Health Research Subgroup Research Priorities Version 1.0 (current as of January 1, 2024)]. DISCUSSION: Research is needed to identify how to optimize and screen mental health across aviation SSP. This effort identified six key research priorities to achieve that aim.
