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.
