Quality control of GNSS-Receivers by accuracy-based analysis.
SMTDA 2014 - 3rd Stochastic Modeling Techniques and Data Analysis International Conference, Lissabon, Portugal, Juni 2014.
In this paper we present a quality control method for Global Navigation Satellite System (GNSS) receivers. A Statistical quality control (SQC) approach is proposed, focused on quantitative trueness, precision and position availability analysis of GNSS receivers’. The position availability is described as the percentage of the total received data that can be considered accurate under n-Sigmas boundaries; being n the level of requested accuracy. As part of this accuracy-based position availability analysis several filters techniques are tested, in order to select the most reliable for this specific quality control method. Traditional statistical methods are compared with Particle Filter (PF) approach and Mahalanobis Ellipses Filter (MEF) approach. The quality control method is depicted in graphical representation. And the results are analysed from an end-user point of view. A detailed description of the receiver’s characteristics and conditions of the measurements are presented as part of a case study. Significant differences between proposed approaches are shown.
