Using GCS (Mission Planner)
In our project, we've developed a customized version of Mission Planner, an open-source software platform known for its capabilities in orchestrating high-performance and intelligent UAV (Unmanned Aerial Vehicle) flights. This technology forms the backbone of our innovative approach to avalanche detection and response.
Our system seamlessly integrates Machine Learning (ML) models into the Mission Planner software. These ML models receive avalanche data and leverage it to create survey regions and autonomously configure waypoints for our Vertical Take-Off and Landing (VTOL) drones.
Once activated, our VTOL drones take flight automatically and navigate to the designated survey regions. These drones are equipped with specialized sensors, which include [Insert Sensor Name]. These sensors play a pivotal role in identifying casualties in avalanche scenarios, whether they are human or animal. Importantly, they have the capability to precisely pinpoint the exact coordinates of individuals potentially trapped beneath snow debris.
The location data of these casualties is then transmitted back to our Ground Control Software (GCS), a vital component of our operation. Our GCS serves as the central hub for coordinating response efforts. It allows us to dispatch relief teams promptly to assist the casualties. Communication and remote control are facilitated through the MAVLINK protocol, ensuring seamless and efficient operations.
This integrated remote sensing system is a game-changer, dramatically reducing the time needed for search and rescue teams to locate individuals affected by avalanches. Ultimately, it significantly enhances the chances of survival for those in distress, reinforcing our commitment to avalanche safety and response excellence.
Multispectral imagery plays a pivotal role in geospatial analysis, often harnessed through powerful tools like Google Earth Engine and QGIS. These images capture data across a spectrum of wavelengths, allowing us to observe a wide range of information about our planet's surface. In particular, C band, a segment of the microwave spectrum, is frequently utilized. C band radar data, commonly acquired from satellites, provides valuable insights into various Earth processes, including land cover changes, soil moisture levels, and vegetation health. With the computational capabilities of Google Earth Engine and the geospatial processing capabilities of QGIS, researchers and environmental analysts can harness multispectral imagery, including C band data, to gain deeper insights into Earth's dynamic systems, facilitating informed decision-making and sustainable environmental management.
Sensor Systems Evaluation for Avalanche Detection
The assessment of sensor systems for avalanche detection revealed varying degrees of capability. Of paramount importance in avalanche hazard evaluation is the ability to detect layering within the snowpack. Ground Penetrating Radar (GPR) proves instrumental in this regard. However, the layers within the snowpack can differ significantly due to factors such as surface frost and snow crystal composition. As a result, there is a need to correlate the snow layers identified by GPR with the hardness scales traditionally employed by avalanche professionals during snow pit assessments. This correlation effort is crucial to showcase that GPR can consistently and successfully locate layers of interest.
Aerial Surveillance for Avalanche Monitoring
In collaboration with the Norwegian Public Roads Administration (NPRA), we've harnessed a fleet of aircraft to enhance our avalanche monitoring capabilities. These aircraft are classified into quadrotors, multirotors, helicopters, and fixed-wing planes. Fixed-wing aircraft excel in winter conditions and can cover vast distances and altitudes necessary for avalanche feature observation. However, they lack the stability of multirotors, which can hover in place. Fixed-wing planes also require more complex takeoffs and landings, often involving launching catapults or parachute systems. Multirotors, on the other hand, offer stability and versatility, making them ideal for transporting sensors to specific locations.
Airborne Sensor Technologies
Literature review has confirmed the potential of airborne sensor technology for measuring snow volumes, intensity, and detecting vulnerable layers beneath the snow. LIDAR (Light Detection and Ranging) is a notable technology that employs pulsed laser light to measure distances to the Earth's surface. While LIDAR systems designed for Unmanned Aerial Systems (UAS) are commercially available, their usage for snow surface and avalanche hazard assessment remains limited. LIDAR holds the promise of mapping the snowpack surface and identifying avalanche indicators such as cracks.
Photogrammetry, also known as Structure from Motion (SfM), can create 3D images from multiple 2D photographs, providing valuable insights for avalanche monitoring.
Ground Penetrating Radar (GPR)
Ground Penetrating Radar (GPR) utilizes electromagnetic radiation pulses to penetrate the ground and capture subsurface images. Traditionally mounted on carts or sleds, GPR has recently been adapted for use on manned aircraft. This innovation has found applications in glaciology and avalanche victim search operations, enhancing our ability to locate and rescue avalanche victims.
Aircraft Payload-Range Performance Evaluation
To optimize aircraft performance, we perform comprehensive payload-range evaluations. This analysis considers various factors, including aircraft operational weights and their impact on payload-range performance. Specifically, we focus on Maximum Take-off Weights (MTOW) and their components to determine payload capacity at different levels and range capability with specific payloads.
For any aircraft with a specified Maximum Zero Fuel Weight (MZFW), the maximum payload can be calculated as:
Max Payload = MZFW – OEW (Operational Empty Weight)
This calculation helps us efficiently utilize aircraft payload capacity for avalanche response missions.
These technologies and evaluations collectively contribute to our mission of enhancing avalanche detection, response, and victim rescue, reinforcing our commitment to safety and excellence in avalanche management.
