 Press Releases

  • The lightest, most accurate and cost-effective UAV LiDAR system in its class. Shanghai, China - March 22, 2021 - CHC Navigation (CHCNAV) announced the release of the AlphaAir 450 (AA450) LiDAR system. The AlphaAir 450 is a very lightweight and compact all-in-one sensor. Featuring internal IMU, GNSS, 3D scanner and camera, the AlphaAir 450 solution is widely used for power line inspection, topographic mapping, emergency response, agricultural and forestry surveys, and more. The unit is easy to use, and it is allowed for rapid deployment in the field. "Despite the fact that the LiDAR scanning is an efficient technology to capture 3D data, it still often remains costly and complex to operate," said Andrei Gorb, Product Manager of CHC Navigation's Mobile Mapping Division. " Taking that into account, we introduce the AlphaAir 450 (AA450), a breakthrough LiDAR scanner, that delivers user-friendly and high-accuracy capabilities at a reasonable price.” There are three key aspects of the AlphaAir 450 that quickly created a buzz in the drone users’ community as a new solution for capturing geospatial data: Lightest unit in its class - With this new compact and lightweight solution that can be easily mounted on UAVs, data capture has become faster and more efficient. The LiDAR's weight is a constraint for any drone. The AlphaAir 450 weighs 1 kg, which is perfectly suited to the drones' payload requirements. The lighter the unit, the longer the operating time of the drone, and the greater the productivity. Advanced Accuracy - By combining industrial grade GNSS with a high precision IMU, the AlphaAir 450 can easily achieve an absolute accuracy of 5 cm (vertical) and 10 cm (horizontal) for small survey areas, which is typically adequate for the most use cases. To further improve precision and accuracy, users can apply adjustment algorithms in the CHCNAV CoPre software. Industrial Reliability - Featuring IP64 high-level protection, the AlphaAir 450 extends its operating temperature capabilities, down to -20℃ and up to +50℃, in any field environment and increases users' return on investment by providing more field survey days in a year.
  • A fully autonomous, survey-grade Vertical Take-off and Landing fixed-wing drone for surveying and mapping applications. Shanghai, China – May 20, 2021 – CHC Navigation (CHCNAV) releases the P330 Pro VTOL UAV, a high-performance vertical take-off and landing (VTOL) fixed-wing unmanned aircraft vehicle (UAV), specially designed for aerial surveying and mapping applications. With its concept of high accuracy, long-endurance and multiple payloads, P330 Pro meets the requirements of professionals in mining, construction and infrastructure, environmental monitoring, and the agriculture industry. “P330 Pro changes the way to capture geospatial information. Surveyors and engineers no longer need to spend time on fieldwork preparation to set up GCP systematically to reference the survey. P330 Pro provides professionals with an innovative and versatile platform that can hold an orthophoto camera or optional sensors, such as an oblique camera. Moreover, its integrated GNSS and IMU modules meet the most demanding requirements for mapping and topographic surveys,” said Dylan Cao, Product Manager at CHC Navigation’s UAV Division. “As a result, the use of the P330 Pro UAV compared to less versatile UAV solutions allows aerial survey companies to significantly improve their return on investment.” CHC Navigation P330 Pro UAV solution is packed with the features to make it the most powerful VTOL drone on the market. Long Endurance, High Efficiency –The P330 Pro VTOL drone achieves longer flight time, for the missions up to 150 minutes duration and to map a region of up to 20 km² at a scale of 1:2000. It integrates a high-accuracy GNSS RTK/PPK module with up to 100 Hz differential data update rate for ultimate accuracy. Mapping anywhere – No runway and no extra equipment are needed for takeoff and landing. P330 Pro, as efficiently as a fixed-wing airplane, can take off and land almost anywhere – even in confined spaces or on rough terrain. Easy and Safe Operation –The P330 Pro is packed with the latest aviation technologies such as dual GNSS system, triple IMU systems, five safe return to base strategies, and nine security monitoring checks. Those technologies ensure the safety of flight operations and the reliability of aerial survey results.The EasyFly ground control software makes mission planning and pre-flight checks easier and safer. Compatible with many airborne sensors – P330 Pro makes no compromises on aerial image quality. Whether you need data for orthophotos, 3D models or multispectral mapping, P330 pro carries the best camera for every application. By exchanging cameras in the field, various types of data can be acquired with the same drone.


  • AlphaAir 450 Airborne LiDAR + RGB System
    The AlphaAir 450 solution is used for power line inspection, topographic mapping, agricultural and forestry surveys, and more. The unit is easy to use, and allows for rapid deployment in the field....

  • By combining an industrial grade GNSS with a high accuracy IMU, the AlphaAir 450 can easily achieve an absolute accuracy of 5 cm (vertical) and 10 cm (horizontal). AlphaAir 450 is ready for direct connection to a DJI M300 via its built-in Skyport and can be mounted on the CHCNAV BB4, other multi-rotor drones and VTOLs easily. Users will get a long range scan up to 450 m with high point density over the measured area (about 280 pts/m2 at a flight height of 100 m and a speed of 5 m/s). Its high-resolution 24 MP camera has the same FOV width as the Livox LiDAR to provide full point cloud coverage by RGB colorization.
  • BB4 UAV Multirotor Drone Platform
    The BB4 is a high-end unmanned aircraft system. Its highly integrated production technology comes from CHCNAV, and its fully automated flight control system from DJI, the pioneer in the manufacturing of commercial UAVs....

  • The BB4 UAV is a high-end multirotor drone optimized for the CHCNAV AlphaUni 300/900/1300 LiDAR scanner series. Its 7 kg payload breaks the capacity barrier, and over 45 minutes of flight time redefines the LiDAR airborne survey ability. In addition, the dual DJI A3 IMUs and GNSS units provide reliable centimeter RTK positioning, meeting the demand for high accuracy in the geospatial and mapping industry.
