Airframe, Powertrain, And Flight Performance Specs
The airframe uses carbon-fiber composites and modular hardpoints for payload swaps. The HSRealist powertrain combines brushless electric motors with hybrid range extenders in longer missions. Peak cruise speed reaches 72 km/h and top speed reaches 110 km/h. Typical endurance runs 3.5 hours on battery-only and up to 8 hours with the range extender. Maximum takeoff weight sits at 18 kg with a 6 kg useful payload. The drone supports VTOL transitions and fixed-wing cruise to cover large stands with lower energy use than multirotors.
Sensor Suite: Perception, Mapping, And Environmental Sensing
HSRealist packs a lidar sensor with 240 k points/sec for canopy and ground models. It includes a 48 MP RGB camera with mechanical stabilization for orthomosaics. The drone carries multispectral sensors for vigor indices and a thermal camera for heat-stress detection. GNSS uses dual-band RTK for centimeter-level positioning. Onboard IMU and barometer support stable flight in variable wind. The sensor fusion yields reliable digital terrain models, tree-height estimates, and canopy gap maps. Teams export standard formats like LAS and GeoTIFF for easy analysis.
Payload Options And Logging-Specific Tools
Payloads include a lightweight winch, grapple module, and precision drop system for marking or delivering gear. A modular sensor bay supports additional payloads like biomass scanners or DBH (diameter at breast height) profilers. The winch lets the drone place remote markers or small tools on steep slopes. The grapple module supports limited sample retrieval and tag placement rather than full log lifting. HSRealist allows quick swaps in the field with tool-swap lanes and hot-swap connectors to cut downtime between tasks.
Autonomy Stack Overview And Operational Modes
The autonomy stack runs on hybrid onboard/cloud compute. It offers mission planning, adaptive re-tasking, and fail-safe behaviors. Operators choose from manual, supervised-autonomy, and full-autonomy modes. Mission plans accept shapefiles and forestry grids. The stack logs telemetry and sensor feeds for post-mission review. Security features include encrypted links and role-based access. The system supports scheduled inspections, reactive surveying after storms, and automatic no-fly checks around protected zones.
Navigation, Collision Avoidance, And Path Planning
The drone uses RTK GNSS and visual-inertial odometry for local positioning. Lidar and stereoscopic cameras feed a local obstacle map. The onboard planner creates collision-free tracks and adjusts altitude to avoid canopy. Path planning supports energy-aware routing and waypoint smoothing to save battery. The system enforces geofence limits and returns to a safe loiter point on link loss. Operators can predefine exclusion zones and preferred corridors to align flights with ground crew movements.
Data Management, Connectivity, And Integration With Forestry Workflows
HSRealist stores mission data locally and syncs to cloud services when a link is available. The platform supports 4G/5G, mesh radio, and short-range Wi-Fi for field transfer. Data exports include LAS, GeoTIFF, CSV, and PDF reports. The API integrates with common forestry systems and GIS tools for inventory and supply planning. Teams automate report generation and alert ground crews with geotagged task lists. The system includes audit logs and user permissions to meet operational and regulatory needs.
