🚀 NAVISP-EL1-055 (MAPP - Maritime Autonomous PNT Prototype) Last week, together with Space Applications, we successfully conducted the second validation campaign of our MAPP Project at the Port of Mallorca. ➡️ MAPP is focused on developing and demonstrating alternative PNT (Positioning, Navigation, and Timing) concepts to enhance ship operations in ports. Our objectives also include the definition and implementation of a multi-sensor integrity concept for both precise position and attitude information. ➡️ Our Setup for this campaign, includes: several IMUs, a Livox AVIA LiDAR sensor, an stereo camera for depth perception and three GNSS receivers, supported by PPP and RTK corrections, for precise position and attitude determination. ➡️ During this campaign, we recorded more than 12.5 hours, across 15 different scenarios, simulating: 👉 👉 Various operations: open waters, port approach, navigation, docking, and departure. 👉 👉Diverse conditions: lighting, weather, and environmental variability. 👉 👉 These scenarios allowed us to explore the robustness and adaptability of our system in dynamic maritime environments. We’re excited by the insights gained and are looking forward to further refining our solutions to meet the challenges of maritime operations.

Underwater technology developer Eelume AS has launched the Eelume-S, an innovative All-Terrain Autonomous Underwater Vehicle (All-Terrain AUV) set to revolutionize underwater exploration. 🌊 Traditionally, AUVs have been limited in their accessibility to underwater environments. Eelume-S overcomes these barriers, offering versatility and sustainability in exploring previously inaccessible environments. 🪨 🪸 Unlike conventional AUVs, the Eelume-S All-Terrain AUVs have 360 degrees of agile maneuverability in roll and pitch, which hugely expands the operational envelope of utilizing AUVs for exploration, inspection and monitoring of critical and complex under­water environments. 💡 Eelume-S contains the Voyis Observer Micro Imaging System, a 4K still image acquisition system with LED panels providing up to 480.000 lumens of light. This results in crystal-clear optical imagery, with onboard image light leveling and color correction, bringing autonomous ocean exploration to new heights. 🔊The Wavefront Systems Solstice Multi-Aperture Sonar enables Eelume-S to carry out leading bathymetric mapping, with 200m swath and resolution down to 3cm. Surveyor classifies as a medium USV, built to American Bureau of Shipping (ABS) Light Warship code.

With its ultra-high-quality data capture, superior maneuverability and easy operation, Eelume-S empowers researchers, scientists, and marine enthusiasts to delve deeper into the mysteries of the ocean.” - Thomas Nygaard, CEO of Eelume.

🌟 Excited to share my latest project: an advanced user detection and tracking system using drone technology! 🚁 The system operates through three main blocks: User Detection: Utilizing real-time feedback, the drone's camera processes frames to identify the user based on the color of their t-shirt using the HSV (Hue, Saturation, Value) color model. This allows for effective contour outlining of the user’s position, enabling precise tracking. User Tracking: By analysing the user's t-shirt contour, we can calculate the distance between the user and the drone, ensuring they stay within a defined area. RRT* Pathfinding: Using the YOLO algorithm, we identify dynamic obstacles and generate a navigable path. The RRT algorithm then computes an optimal path from the user to the destination, which is the bicycle, displayed on the user's laptop for easy navigation. Check out the video showcasing the entire process, including simulations and step-by-step implementation! A special thanks to my partner, Maher Morsi, for his collaboration on this project! I’m eager to hear your thoughts and feedback. #DroneTechnology #UserTracking #ComputerVision #YOLO #RRTPathfinding #Innovation #ProjectShowcase

Unveiling the Depths: Sub Bottom Profiler - A Powerful Ally for AUV Exploration with Hugin 4500+ Autonomous Underwater Vehicles (#AUVs) are transforming how we explore the ocean depths. At #LIGHTHOUSE, we equip our Hugin 4500+ AUV with a powerful 2-16 kHz Chirp Sub Bottom Profiler (SBP) technology, acting as a key tool in our multi-sensor approach. EdgeTech SBP on the #Hugin 4500: This dynamic duo offers: - Unmatched Penetration: SBP excels at revealing hidden details in the near-surface stratigraphy, complementing high-resolution data from other sensors like MBES and HiSas for a complete picture. - Crystal Clear Insights: SBP provides stunning imagery, aiding in the interpretation and analysis of data collected by other tools on the Hugin 4500. - Low-Noise Environment: The Hugin 4500's optimized design minimizes noise interference, ensuring the SBP delivers the clearest possible signal for exceptional data quality and great penetration in marine sediemnts. The Hugin 4500, equipped with SBP and a suite of other advanced sensors, provides: - Unwavering Reliability: Seamless operation for extended missions, even in challenging environments. - Unveiling Efficiency: AUV autonomy allows for wider coverage and faster data collection compared to traditional methods. - Symphonic Insights: The combined power of SBP with MBES, HiSAS, magnetometers, color cameras and a suites of environmental sensors, unlocks a deeper understanding of the ocean floor and its secrets. This translates to: - Reduced Costs: Efficient data collection saves time and resources compared to manned vessel operations. - Safer Operations: Exploration of hazardous areas without putting personnel at risk. - Actionable Data: Combined sensor data empowers informed decision-making for your project needs. Considering a project requiring high-resolution sub-bottom exploration? Our AUV Hugin 4500+ is the answer. Let's discuss how we can tailor a solution for you.

“Buttery smooth OIV [Operational Intent Volume] following”. Taken from our debrief notes after braving the elements to attend another ALIAS flight trial in February. We couldn’t have asked for much more than buttery smooth OIV following from that session! This was for Flyte our intelligent tactical guidance software that simultaneously maintains mission conformance (follows 4D waypoints with second-level precision) with autonomous proportionate response to real time hazards, i.e., the artificial pilot. What does this mean? Operating long range missions, which run on route and on time, arriving safely with no need for human intervention. The mission conformance functionality is fundamental to achieving truly integrated skies - where BVLOS aircraft are able to book short tunnels of airspace for short time intervals rather than whole corridors for the entire flight.So back to this month, the new functionality we tested and demonstrated includes: ⭐ Consistent spatial and temporal OIV following of an onboard autonomous system. If the craft is too late, early or spatially off course the system corrects to get back on track. ⭐ Mission integration with the operator: the operator (trialled with SkyLift) can update their mission and Flyte updates to follow the new mission autonomously. ⭐ Stable UI into the system: Vision, our insight into data in ALIAS, was put through the gauntlet with loss of comms and stress tests. The gains which can be made when collaborating with partners are becoming increasingly evident as we head toward our demonstrator this summer. A huge congrats to the ALIAS consortium who demonstrated huge progress in joint operations - worth shivering in a field in Wiltshire for. We’re looking forward to our first trial in Jersey. Keep watching! #FlightTrials #testing #uav #uas #FutureFlight #InnovationInAviation

July 23-31, a team of researchers on Research Vessel Pacific Storm off the coast of Oregon will demonstrate their new approach to efficiently and effectively map and characterize methane seeps over wide areas. During this second of two expeditions, the team will use easily deployable and relatively inexpensive autonomous underwater vehicles equipped with imaging sonars and custom sensors to improve our understanding of how methane from these seeps influences life on the seafloor and in the water column as well as its role in the global carbon cycle.
