Background:

Advanced navigation systems rely on multi-sensor fusion, where individual sensor data quality varies by environment.
Accurate environmental scene detection is crucial for optimizing sensor weighting in multi-source fusion positioning.

Purpose of the Study:

To develop a context-aware scene sensing model for smartphone-based multi-sensor fusion navigation.
To improve positioning accuracy by accurately identifying indoor, semi-indoor, outdoor, and semi-outdoor environments.

Main Methods:

Utilized multi-source data from Global Navigation Satellite System (GNSS), Inertial Measurement Units (IMUs), cellular, optical, and Wi-Fi sensors.
Constructed a multi-scale, multi-window, context-connected scene sensing model incorporating Convolutional Neural Networks (CNN) and Bidirectional Long Short-Term Memory (BiLSTM) networks.
Employed meta-heuristic optimization algorithms for model refinement.

Main Results:

The model accurately detects diverse environmental scenes (indoor, semi-indoor, outdoor, semi-outdoor).
Scene detection provides a foundational basis for adaptive multi-sensor fusion localization.
Enhanced understanding of temporal, spatial, and statistical features of sensor data.

Conclusions:

The developed scene sensing model significantly improves the basis for multi-sensor fusion positioning.
This approach offers a robust solution for enhancing navigation accuracy in varied environments.
The study highlights the importance of environmental context in sensor fusion algorithms.
