A method for GNSS positioning performance assessment for location-based services

Development of Global Navigation Satellite System (GNSS) applications requires a methodology for GNSS positioning performance assessment in targeted GNSS positioning environment conditions, and its compliance with requirements of targeted GNSS application. We propose such a methodology that utilizes experimentally collected GNSS observations in the GNSS positioning environment conditions of concern, and open-source software. The proposed methodology include the GNSS observations collection with the consumer-grade smartphone GNSS receivers, and statistical analysis of the estimated components of the post-processed GNSS positioning error vector. Demonstrated in the real scenario of the GNSS positioning performance assessment based on experimental data, the proposed methodology was proven to become an indispensable tool for GNSS applications developers, operators and users, especially in the segment of Location-Based Services.
