Shuttle Software – High-Precision GNSS/INS Post-Processing System
Independently Developed by Geosun Navigation
Shuttle is a high-performance GNSS/INS post-processing software independently developed by Wuhan Geosun Navigation Technology Co., Ltd. It is designed to provide centimeter-level positioning, velocity, and attitude data through advanced processing of multi-source GNSS and inertial measurements.
Equipped with the self-developed GGPoS engine, Shuttle supports GPS, GLONASS, BeiDou II, and Galileo data, enabling:
Multi-mode GNSS positioning and velocity calculation
GNSS/INS integrated positioning and attitude solution
Centimeter-level position and velocity output
Milliradian (thousand-degree) attitude accuracy
Core Technologies
Shuttle integrates:
Single-Epoch Ambiguity Resolution – Enables fast and accurate GNSS phase resolution
High-Order Kalman Filtering – Fuses GNSS and IMU data with high precision
IMU Compatibility – Supports both incremental and rate-based IMU types, with flexible modeling of random errors
Robust GNSS/INS Integration – Offers more complete motion dynamics than standalone GNSS solutions
This powerful combination results in improved positioning accuracy, enhanced reliability, and richer dynamic trajectory information—surpassing many international alternatives, especially in localized performance for Chinese users.
Applications
Shuttle is widely used in:
Aerial photogrammetry
Urban mobile mapping
Railway and smart transportation systems
Aerospace platforms and unmanned vehicles
Its modular architecture allows for flexible expansion and customization, making it adaptable to diverse high-precision positioning needs.
