SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you analyze sensor configurations and reliably create and tune inertial fusion filters in MATLAB Navigation Toolbox so your agent can estimate orientation or full pose from IMU/AHRS/INS data with the correct algorithm choice.

Core Features & Use Cases

  • Filter selection from sensor availability: Chooses among imufilter, ahrsfilter, complementaryFilter, ecompass, ahrs10filter, insfilterMARG, insfilterAsync, insfilterNonholonomic, insfilterErrorState, insEKF, insCF based on whether you have gyro, magnetometer, altimeter, and GPS and whether you need real-time vs batch processing.
  • End-to-end fusion workflow guidance: Covers construction options, correct sample-rate handling (SampleRate vs IMUSampleRate vs timestamp-driven), handling time gaps, and implementing predict/fuse loops or batch estimateStates workflows.
  • Tuning and validation support: Guides correct tune signatures (in-place vs tunernoise+returned noise struct), tuner configuration, and practical output/pose extraction patterns (pose vs stateparts/estimateStates timetable).
  • When NOT to use: Explicitly avoids vision-only SLAM and Simulink model-based fusion, and flags simulation/data-only workflows where a filter isn’t the right tool.

Quick Start

Use the matlab-fuse-inertial-sensors skill to generate MATLAB code that selects the best Navigation Toolbox inertial fusion filter for your specific IMU/magnetometer/GPS/altimeter setup and runs or batches the fusion loop to produce orientation (and optionally position/velocity) from your recorded sensor data.

Frequently Asked Questions about matlab-fuse-inertial-sensors

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I choose the right MATLAB Navigation Toolbox filter for my IMU and GPS sensor setup?▼

To choose a MATLAB inertial fusion filter, match your sensor availability to the algorithm: imufilter for 6-axis gyro/accelerometer data, ahrsfilter or insfilterMARG for 9-axis magnetometer data, and insfilterAsync for mixed-rate GPS fusion.

How do I tune an inertial navigation filter in MATLAB using the tune function?▼

To tune an inertial navigation filter in MATLAB, use the correct tune signature with tuner configuration and tunernoise parameters to adjust noise structs, ensuring accurate orientation and pose estimation for your specific IMU sensor data.

What is the difference between real-time predict/fuse loops and batch estimateStates workflows in MATLAB sensor fusion?▼

Real-time predict/fuse loops process streaming IMU data incrementally as it arrives, while batch estimateStates workflows process complete recorded sensor timetables at once to extract orientation and pose states in MATLAB.

How do I handle mixed sample rates and timestamps when fusing GPS with IMU data in MATLAB?▼

When fusing GPS with IMU data in MATLAB, handle mixed sample rates by using insfilterAsync, which manages asynchronous sensor inputs through correct SampleRate, IMUSampleRate, and timestamp semantics to maintain accurate navigation.

Does MATLAB sensor fusion support vision-only SLAM or Simulink model-based fusion?▼

MATLAB sensor fusion does not support vision-only SLAM or Simulink model-based fusion, focusing instead on Navigation Toolbox algorithms for IMU, AHRS, and INS sensor data estimation workflows.

How do I extract orientation and pose from an insfilterMARG or insEKF state vector in MATLAB?▼

To extract orientation and pose from insfilterMARG or insEKF in MATLAB, use the estimateStates timetable for batch processing or access stateparts directly to retrieve position, velocity, and orientation from the filter state vector.
