  • Wingcopter drones conduct aerial surveys in Japan

    Wingcopter drones conduct aerial surveys in Japan

    Wingcopter’s authorized partner in Japan, ITOCHU Corporation, has signed a Memorandum of Understanding (MOU) to collaborate on the practical use of Wingcopter’s long-range drones in aerial surveying together with PASCO Corporation and YellowScan Japan.

    The companies initially plan to use the Wingcopter 198 in disaster management where drone-based surveying is playing an increasingly important role,

    • to create hazard maps and monitor ground deformation as part of effective pre-disaster prevention,
    • to gather information and assess damage in the event of a disaster, and
    • to measure terrain changes and develop recovery plans during post-disaster restoration.

    According to Wingcopter, carrying out these tasks is easier and less risky with fixed-wing drones such as the Wingcopter 198 than with traditional human or aircraft-based methods.

    About 70 percent of Japan’s land consists of mountainous and hilly terrain, with steep slopes and short, fast-flowing rivers. Conventional multicopter droneswould not be suitable for such tasks as they are limited in range and coverage compared to the Wingcopter 198.

    Under the MOU, YellowScan Japan’s advanced lidaer scanner Voyager will be used on the Wingcopter 198. By integrating this technology with PASCO’s extensive expertise in operational quality and safety in aerial surveying, it is possible to carry out long-distance and large-area surveys that were previously difficult to achieve without manned aircraft. 

    In a single 45-minute flight, the Wingcopter 198 can scan 1,000+ hectares, simultaneously capturing lidar and RGB data, allowing the system to generate an exceptionally high point density and precision. This makes it suitable even for demanding applications.

    The collaboration also promotes automation and labor savings in surveying tasks, contributing to sustainable development in the surveying industry and reducing disaster risks.

  • Harxon introduces all-constellation GNSS antenna for surveying and mapping

    Harxon introduces all-constellation GNSS antenna for surveying and mapping

    Harxon has released the all-constellation GNSS antenna GPS1000, receiving GPS L1/L2/L5, BDS B1/B2/B3, GLONASS L1/L2, Galileo E1/E2/E5a/E5b and L-band signals.

    GPS1000 can be used in land survey, marine survey, channel survey, seismic monitoring, bridge survey and agriculture applications, providing consistent performance across the full bandwidth, the company said.

    The antenna has high gain and wide beam width to ensure the signal receiving performance of satellite at the low elevation angle, and the phase center remains constant as the azimuth and elevation angle of the satellites change.

    Placement and installation of the antenna can be completed with ease because the signal reception is unaffected by the rotation of the antenna or satellite elevation. The influence of measurement error can be minimized via the multi-feed design and embedded multipath rejection board.

    The GPS1000 waterproof and dustproof design has reached a standard of IP67, maintaining good performance for long-time outdoor operation.

    Moreover, the advanced low noise amplifier can reduce jamming by high-power out-of-band transmitters. It can be customized for the best solution for customers, Harxon said.
