Abstract:Since a single indicator or a simple combination of several indicators that cannot effectively characterize the GNSS positioning quality, we propose a comprehensive evaluation indicator. This indicator normalizes the observation data quality indicators and GNSS positioning processing algorithm feature data, and uses the coefficient of variation weighting method to linearly combine several indicators. The new indicator is a comprehensive evaluation indicator, with smaller value indicating higher quality. The results show that the new indicator is an effective evaluation indicator for the positioning quality, which can be used in engineering practice and provide a new idea for the quality assessment of GNSS positioning.
