SITE-SPECIFIC UNMODELED ERROR MITIGATION FOR GNSS POSITIONING IN URBAN ENVIRONMENTS USING A REAL-TIME ADAPTIVE WEIGHTING MODEL

Site-Specific Unmodeled Error Mitigation for GNSS Positioning in Urban Environments Using a Real-Time Adaptive Weighting Model

In Global Navigation Satellite System (GNSS) positioning, observation precisions are frequently impacted by the site-specific unmodeled errors, especially for the code observations that are widely used by smart phones and vehicles in urban environments.The site-specific unmodeled errors mainly refer to the multipath and other space loss caused by t
