Product Introduction
The RTK-N7AR Visual Staking System combines RTK technology with imagery, allowing staking points to be marked directly on the ground within the image. This eliminates the need for repeated pole repositioning, ensuring precise staking in a single pass. Powered by a fusion algorithm that integrates satellite navigation, inertial navigation, and visual data, the system is immune to electromagnetic interference, delivering highly efficient and accurate staking. With its immersive real-world staking capability, the process is both fast and precise.
Double Your Staking Efficiency with AR
AR real-world navigation provides real-time guidance on the direction of staking points, eliminating the need for repeated movement to verify locations. It allows for quick and precise point identification, enabling you to stake points in a single attempt and significantly boosting staking efficiency.
Seven Constellations, 30 Frequencies-Worry-Free Signal Reception
Fully supports BeiDou-3 satellite signals, with over 50 available satellites and up to 1,590 parallel channels for full-constellation tracking. Unfazed by obstructions, it delivers outstanding performance even in complex environments.
Satellite-based technology works even without an internet connection
A brand-new generation of satellite-based enhancement algorithms achieves centimeter-level accuracy. The RTK and satellite-based fusion algorithms enable faster satellite-based convergence. We provide Beidou B2B and Galileo HAS satellite-based services free of charge for life.
Third-generation inertial navigation system-highly efficient and convenient
No need for alignment within a 60° tilt angle; no need to check the bubble level; simply rest the pole on your shoulder and start measuring the moment you "tap," while maintaining centimeter-level accuracy, dramatically boosting surveying and staking efficiency
