High-Precision Positioning
GNSS · IMU · RTK corrections · Algorithms
Built on proven mass-production positioning technology, we close the loop between satellite-inertial hardware, high-precision algorithms and correction data — one complete solution that brings accuracy to the centimeter level and time-to-fix down to seconds.
Product families
From module to service, one integrated stack.
Self-developed GNSS and IMU products at the core, completed by terminals, correction services and algorithms — available as individual components or as a full solution.

Global correction services
Centimeter-level corrections across three continents.
N-RTK and PPP-RTK services covering China, Europe and North America. Correction data is stored, computed and broadcast from the cloud, then combined on the device with GNSS tracking the same constellations as the reference stations, an IMU tier matched to the application, and standard or custom positioning algorithms — closing the loop to centimeter-level absolute positioning.
Redundant by design: dual receivers at every reference station, dual data-center links and dual communication paths. Supports ITRF2014, CGCS2000 and WGS84. The service holds a Class-A surveying & mapping qualification and MLPS Level 3 cybersecurity protection.
