FOIF Attended Exchange Meeting 2025

FOIF Attended Exchange Meeting 2025

On March 25th, 2025, the China Surveying, Mapping and Geographic Information New Technology and Equipment Application Exchange Conference was held in KunMing, China. Engineers from FOIF published a theme report on "Technology Breakthrough and Domestic Pilot - Innovation and Application of High-precision Surveying and Mapping Instruments". Domestic equipment station on the innovation highland: RS10 direct-drive robotic total station, developed by FOIF, utilizes domestic absolute code angle measurement technology, ensuring high precision and stability in applications such as automated deformation monitoring, settlement monitoring, and bridge monitoring, capable of achieving 0.5” angle measurement accuracy and supporting 24-hour unattended deformation monitoring; EL03PRO digital level improves measurement efficiency by 40% compared to traditional equipment, due to its ability to quickly point at targets via image recognition; The A10AR RTK features a pocket-friendly design, offering support for a 7-star constellation and a 31-frequency range, ensuring that measurements are not burdensome and accuracy is readily achievable. The conference set up a special equipment experience area, and FOIF showcased an array of innovative products, including RS10 direct drive robotic total station, EL03PRO digital level, RTS010N Android total station, the A10AR RTK, A66AR RTK, and various other surveying and mapping equipment. RS10 total station demonstrated its dynamic monitoring capabilities, while the A10AR RTK, weighing just 390g and palm-sized, fits easily in your pocket for ultimate portability. During the meeting, the participants had in-depth exchanges with our technical personnel, and experienced the automation application of RS10 robotic total station in deformation monitoring, and the exchange atmosphere was warm. Looking forward to the future, FOIF will continue to advance in localization, embracing technological innovation and service innovation, while launching more high-precision and intelligent surveying and mapping products to drive high-quality development.
