Machine learning framework enhances GNSS positioning accuracy in urban areas

Researchers have developed a new machine learning framework to improve the accuracy of Global Navigation Satellite Systems (GNSS) positioning, particularly in challenging urban environments. The system uses activation functions to transform machine learning predictions about signal quality into weights for a weighted least squares algorithm. Experiments in Hong Kong and Tokyo showed that sigmoid activation functions consistently provided the most significant improvements in positioning accuracy across various machine learning models and GNSS configurations.
