Findings improve general fault detection and isolation in multi-sensor navigation systems by allowing access to all raw measurements' residuals.
Castelldefels, 15 January 2021. On the 14th of January, Dr. Maria Eulàlia Parés defended her doctoral research in a "viva voce" examination before a committee of experts in geodesy, navigation and sensorics. The granted doctoral degree belongs to the PhD Programme in Aerospace Science and Technology (DOCTA) of the Universitat Politècnica de Catalunya (UPC). The title of the doctorate thesis was "A geodetic approach to precise, accurate, available and reliable navigation."
Dr. Parés, a researcher of the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), presented the geodetic approach to navigation with emphasis on generic abstract modelling and general outlier detection for accurate and reliable navigation. Among other contributions, a highlight of her research was a non-linear simultaneous prediction and filtering (SiPF) method to be used in combination with predictive filters, e.g. the Kalman filter and its many variants. More specifically, she presented a method to estimate the residuals of the measurements that participate in predictions before they are spread into correlated errors affecting the predicted states. The thesis supervisor was GeoNumerics' Dr. Ismael Colomina.
