Dramatically streamline measurement operations! CHCNAV's "LiDAR × Drone × GNSS" total package launched domestically.

High-end performance at less than half the cost. UAV LiDAR 'CHCNAV AA9' suitable for public surveying.

"I want to introduce high-precision laser surveying, but cost is a barrier," and "I am struggling to obtain surface data in forested areas." The latest UAV LiDAR from CHCNAV, the 'AlphaAir 9 (AA9),' solves these challenges. This product, provided by SkyLink Japan, features a lightweight body of 1.45 kg, with long-range scanning capabilities of up to 700 meters and high-speed performance of 600,000 points per second. It offers "public surveying level" accuracy comparable to high-end models at an overwhelming introduction cost.

We have updated the catalog for cerium polishing materials and cerium oxide. We have provided information focusing on the products that are currently in high demand. Please take a look and feel free to reach out to us. Thank you very much.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. We have many implementation examples available, so please take a look at the case study page.

The Natural Disaster Prevention System ZEROSAI has been utilized by many general contractors since its launch. Since the start of operations, it has been implemented at over 1,000 civil engineering and construction sites and is currently being widely used as a weather countermeasure on construction sites. As a successor service to the Natural Disaster Prevention System ZEROSAI, we will release the Comprehensive Weather Platform ZEROSAI X-AI on February 18, 2026. ZEROSAI X-AI can centrally manage weather forecasts for construction sites, weather and environmental data, and hazard notifications. It allows all personnel on site to visualize various dangers such as sudden heavy rain, strong winds, heatstroke measures during summer, linear precipitation zones, and typhoons. While leveraging the strengths of traditional centralized management, we have newly added an AI-based wind speed forecasting feature. Additionally, various functions such as chatbots have been added or improved, making it even more convenient. For service details and catalogs, please visit our website.

SkyLink Japan has strengthened its sales and support system for CHCNAV's latest 3D measurement solutions to accelerate DX in the surveying and civil engineering industry. We propose an efficient workflow that combines the UAV LiDAR "AA9," the surveying drone "X500," and the visual GNSS receiver "i93."
