GGPoS – Precision GNSS Data Processing for Positioning & Velocity
GGPoS is a high-performance GNSS post-processing software developed by Geosun Navigation, capable of handling single- and dual-frequency data from GPS, GLONASS, BeiDou, and Galileo systems. It accurately computes centimeter-level positions and millimeter-per-second velocity, leveraging carrier phase measurements for reliable output.
The system integrates an industry-leading single-epoch ambiguity resolution algorithm, enabling rapid solution convergence without the need for traditional initialization procedures. This ensures robust, consistent performance in both stable and dynamic operational environments.
Highlights
-
Multi-system, multi-frequency GNSS compatibility
-
Immediate high-accuracy positioning with no initialization wait
-
Reliable results even under challenging field conditions
-
Fine-resolution carrier phase velocity output
