Vision RTK Pro with Dr. Zhenzhong Su | Fixposition AG

In this session, Dr. Zhenzhong Su (Fixposition AG) introduces Vision RTK Pro, a positioning solution that combines GNSS, stereo vision, IMU, and AI to extend centimeter-level RTK performance beyond open-sky environments. The goal: maintain stable, high-precision global positioning even in GNSS-disrupted or denied areas—while simplifying field workflows. At the core is Fixposition’s sensor-fusion algorithm, tightly coupling raw GNSS (carrier phase, Doppler, pseudorange), visual features, and inertial data in a globally optimized estimator. AI supports adaptive sensor weighting and object detection, enabling robust localization indoors, near reflective surfaces, and during GNSS outages. Features include X-RTK (continuous positioning across indoor/outdoor transitions), X-Start (instant reinitialization without waiting for GNSS fix), X-Tilt (vision-based tilt compensation at any angle), and X-PPK (visual-assisted post-processing for improved accuracy during long outages). The highlight is Perceptive Localization: beyond positioning the sensor itself, Vision RTK Pro detects objects of interest and estimates their 3D coordinates—unlocking new use cases such as automated road inspection and mobile asset mapping. The message: one intelligent device can reduce crew size, accelerate workflows, and maintain quality—without switching between RTK and total stations. 🛰️ About the Speaker Dr. Zhenzhong Su is CEO and Co-Founder of Fixposition AG. A geomatics engineer with a PhD in positioning technologies, he founded the company to make centimeter-accurate global positioning reliable across more environments and industries. Fixposition provides full-stack positioning solutions—from compact sensor modules to software licensing for high-volume OEM integration. 🎯 Top 5 Key Topics ✔️ Deep fusion of GNSS, stereo vision, IMU & AI for robust centimeter positioning ✔️ X-RTK: Maintaining accuracy in GNSS-challenged environments ✔️ X-Start & X-Tilt: Instant initialization and tilt at any angle ✔️ Visual-assisted PPK for improved post-processed accuracy ✔️ Perceptive Localization: Measuring objects in 3D using AI detection 📍 Recorded at INTERGEO 2025, Frankfurt am Main 👉 Next stop: Munich – INTERGEO 2026 (September 15–17)! About INTERGEO: 📌 INTERGEO EXPO and CONFERENCE is the international platform for geodesy, geoinformation, and land management. It takes place at changing locations throughout Germany. The CONFERENCE addresses current topics from politics, administration, science, and industry. With its geo-IT potential, INTERGEO continues to focus on optimizing processes in growing target markets. It was held in Frankfurt am Main in 2025. In 2026, it will be hosted in Munich, and from 2027 onwards it will be held permanently in Frankfurt am Main. The organizer of INTERGEO is DVW e.V. – Society for Geodesy, Geoinformation and Land Management. 👉 More information about INTERGEO: https://dvw.de/intergeo/en 📲 Follow us on LinkedIn, Instagram & more for the latest news and highlights! 🔗 LinkedIn:   / intergeo   📸 Instagram:   / intergeo.de   📘 Facebook:   / intergeo.de   ▶️ YouTube:    / @intergeo   🎥 This video is part of our official INTERGEO media library.
