Inertial Navigation Filter Model Customization

The patent segments the navigation component modeling by dividing it into multiple discrete models, each representing different performance categories of navigation components. Instead of using a single generalized model, the system creates separate models for different component types (e.g., different IMU models, GPS models) with specific characteristics tailored to each category, thereby improving measurement precision while managing complexity through structured segmentation

The patent applies local quality by customizing model parameters and characteristics to match specific navigation component performance categories. Each model is locally optimized with parameters that reflect the actual performance characteristics of components in that category (such as noise levels, bias stability, accuracy specifications), rather than using uniform generalized parameters across all components

The patent applies preliminary action by pre-configuring multiple discrete models with optimized parameters for different navigation component performance categories before runtime. During system operation, the appropriate pre-configured model is selected based on the actual component characteristics, eliminating the need for complex real-time model configuration or customization while maintaining high reliability and accuracy

The patent utilizes parameter changes by adjusting model parameters to match specific navigation component performance categories. Each discrete model contains parameters tailored to its intended component type (such as noise characteristics, bias values, accuracy metrics), allowing the system to adapt to different component qualities through parameter selection rather than complex reconfiguration
