The Drone d'Inspection de Précision et Cartographie can simultaneously perform three types of inspections through its integrated triple sensor system. The 48-megapixel RGB camera provides high-resolution visual imagery for structural inspection and visible defect detection (cracks, corrosion, deformation). The radiometric thermal camera (0.03°C sensitivity) enables detection of thermal bridges, insulation leaks, electrical component overheating, and pipeline leaks. The LiDAR module generates exceptionally dense 3D point clouds for precise geometric modeling of structures, volume calculations, and detection of millimeter-scale deformations. All this data can be automatically fused by Lannkin InspectPro software to create a complete digital twin of the inspected infrastructure.

The Drone d'Inspection de Précision et Cartographie integrates a multi-frequency, multi-constellation GNSS receiver (GPS, GLONASS, Galileo, BeiDou) coupled with an RTK (Real-Time Kinematic) module that delivers positioning accuracy of ±2 centimeters horizontally and ±3 centimeters vertically. The system works by receiving real-time corrections from a ground base station (available as an option) or via an NTRIP reference station network. This centimeter-level accuracy is maintained throughout the flight, enabling direct georeferencing of every image and LiDAR point without requiring Ground Control Points (GCPs), significantly reducing post-processing time and increasing mapping mission productivity.

Yes, the Drone d'Inspection de Précision et Cartographie is rated to operate in Beaufort scale level 6 conditions, corresponding to sustained winds of 39 to 49 km/h with gusts up to 60 km/h. This capability is made possible by its six-axis stabilization system, real-time wind compensation algorithms, and oversized motors providing a 40% power reserve. The reinforced carbon fiber structure and locked folding arms ensure the necessary rigidity in turbulent conditions. However, for inspection missions requiring maximum precision (particularly LiDAR measurements), we recommend flying in winds below level 4 (less than 28 km/h) for optimal results.

The four-point attachment system with electromagnetic locking ensures cargo stability in flight. An integrated weight sensor automatically verifies mass before takeoff, and the software adjusts flight parameters (speed, altitude, trajectory) based on actual transported weight to optimize safety and endurance.

Yes, the Drone de Transport Logistique et Levage Lourd (50kg) is designed to operate at up to 4,000 meters above sea level, making it suitable for mountain mining sites, high-altitude hydroelectric projects, and telecommunications installations in mountainous areas. This capability is provided by high-performance propellers specifically profiled for thin air, a motor supercharging system that compensates for reduced air density, and a thermal management system adapted to extreme temperature variations encountered at altitude (-20°C to +45°C). Effective payload decreases gradually with altitude: 50 kg at sea level, approximately 40 kg at 2,000 m, and approximately 30 kg at 4,000 m. The CargoOps software automatically calculates the maximum admissible payload based on mission altitude.

The Drone de Transport Logistique et Levage Lourd (50kg) is designed to operate across a wide range of weather conditions through several protective systems. It carries IP54 certification, protecting against water splashes and dust, enabling operations in light rain and dusty environments like quarries and mines. It withstands sustained Beaufort level 5 winds (29-38 km/h) at maximum payload and level 6 when unloaded. The operational temperature range extends from -20°C to +45°C, covering environments from arctic mines to desert construction sites. The active de-icing system for propellers and sensors enables operations in icing conditions. The CargoOps software integrates real-time weather forecasts and can automatically postpone a mission if conditions exceed safety limits.

The Drone de Transport Logistique et Levage Lourd (50kg) maintenance program is structured in three levels adapted to the demands of heavy transport. Level 1 (pre-flight) includes a complete automatic check performed by the LannCare system before each mission: battery status, sensor calibration, motor condition, and structural inspection. Level 2 (periodic maintenance) occurs every 80 flight hours or 3 months: propeller replacement, motor bearing inspection, visual airframe inspection, and cargo attachment system testing. Level 3 (major overhaul) is performed every 200 flight hours or 12 months: complete motor overhaul, ESC replacement, ultrasonic structural inspection of the titanium airframe, and full navigation sensor recalibration. All-inclusive maintenance contracts are available with a guaranteed 24-hour response time in Europe.

Yes, the Drone de Transport Logistique et Levage Lourd (50kg) is designed to function as part of an autonomous logistics fleet managed by the Lannkin Fleet Manager platform. The system supports continuous loop missions: the drone performs automatic rotations between a loading point and one or more delivery points, with recharging pauses at dedicated charging stations. Multiple Drone de Transport Logistique et Levage Lourd (50kg) units can be coordinated simultaneously to optimize logistics flow: while one drone delivers, another is being loaded, and a third is recharging. The CargoOps software manages mission planning, delivery prioritization, trajectory optimization, and real-time monitoring of the entire fleet. The open REST API enables integration with the customer's existing ERP and WMS systems for complete supply chain automation.

The VTOL combines the best attributes of both architectures. Like a multirotor, the Drone de Patrouille Aérienne Longue Portée can take off and land vertically from any flat 3x3-meter surface without requiring a runway. Like a fixed-wing aircraft, it cruises far more efficiently: its 120-minute endurance is 3 to 4 times greater than a comparable-sized multirotor, and its 110 km/h cruise speed is 2 to 3 times faster. For patrol missions, this means a single Drone de Patrouille Aérienne Longue Portée can cover a surveillance zone 10 times larger than a multirotor, with a 50 km range versus the typical 5-10 km. The VTOL can also hover for detailed observation of a point of interest, then resume its patrol in cruise flight.

The Drone de Patrouille Aérienne Longue Portée has a 50-kilometer operational range through a long-range communication system using an L-band (1.4 GHz) digital radio link with AES-256 encryption, advanced error correction protocol, and adaptive transmission power. Data throughput supports simultaneous real-time HD video streaming from both EO and IR cameras, complete flight telemetry, and target tracking data. In case of temporary link loss, the drone automatically continues its programmed mission and stores data in secure local memory for later transmission. An Iridium satellite communication module is available as an option for missions beyond the radio horizon, in areas without cellular coverage, or for additional link redundancy.

The Drone de Patrouille Aérienne Longue Portée is designed to operate in varied weather conditions. In cruise mode (fixed-wing), it withstands sustained winds up to 45 km/h (Beaufort level 6) and gusts up to 55 km/h, thanks to its optimized aerodynamic profile and adaptive flight control algorithms. In VTOL mode (takeoff and landing), the operational limit is 30 km/h due to wing surface exposure. The drone is IP44 certified, protecting against light rain and airborne particles (dust, fine sand). The operational temperature range extends from -15°C to +50°C. PatrolOps software integrates real-time weather data and automatically calculates wind impact on endurance and trajectory, adjusting the flight plan accordingly. If conditions exceed safety limits, the drone executes an automatic return procedure.

The Drone de Patrouille Aérienne Longue Portée is equipped with a dual EO/IR camera system mounted on a 3-axis gyro-stabilized gimbal. The electro-optical (EO) camera integrates a 20-megapixel CMOS sensor with continuous 30x optical zoom, providing sufficient resolution to identify persons at over 5 kilometers and license plates at 2 kilometers. The infrared (IR) camera uses an uncooled microbolometer detector of 640x512 pixels with 0.05°C thermal sensitivity (NETD), capable of detecting a person at over 3 kilometers in thermal mode and spotting thermal anomalies of a few degrees on infrastructure. The stabilized gimbal maintains precise pointing even in turbulence and enables automatic target tracking through an AI tracking algorithm. Both video feeds are transmitted in real-time HD and can be fused into a composite EO/IR image.

Yes, the Drone de Patrouille Aérienne Longue Portée is designed for recurring autonomous patrol missions through the Lannkin PatrolOps software. The operator defines a patrol trajectory with waypoints, areas of interest (loitering zones for extended observation), and mission parameters (altitude, speed, camera angle). The recurring patrol mode enables programming of automatic missions at defined intervals (e.g., every 4 hours, twice daily, or continuously with automatic recharging). The onboard AI system analyzes video feeds in real time to automatically detect anomalies: unauthorized vehicles, persons in restricted zones, environmental changes (illegal construction, unauthorized dumps), and nascent fires. A comparative report is generated after each patrol, highlighting changes detected compared to the previous patrol. Critical alerts are immediately transmitted to the operator via the Lannkin Fleet Manager platform.
