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

Typical Use Cases

GGPoS is widely deployed across multiple professional domains, including but not limited to:

• Topographic and engineering surveying

• Transportation infrastructure development

• Water resource and hydrological studies

• Power grid inspection and maintenance

• Maritime and offshore surveying

• Railway track monitoring

• Aerospace and airborne mapping missions

Thanks to its modular system design, GGPoS allows for flexible feature extension and customization, offering tailored solutions to fit the needs of diverse applications and user requirements.
