Airborne Ionospheric Gradient Monitoring for Dual-Frequency GBAS

Abstract: 2014. During Master studies he specialized in aerospace technology and navigation. After working in the field of sensor fusion and navigation aiding at Fraunhofer IOSB he joined German Aerospace Center (DLR) in May 2015 and is involved in the research on GBAS and reliable navigation for UAS since then.Maria Caamano received a Master's degree in Telecommunications Engineering from the University of Oviedo, Spain, in March 2015. During Master studies, she specialized in the field of signal theory and communicati… Show more

“…Recently we proposed a new airborne monitoring approach for the traditional GBAS that leverages the use of a second frequency to assess the ionospheric threat at the user side [10], deriving ionospheric protection levels based on the used satellite geometry. This approach is currently under consideration for future dual-frequency GBAS in classical aviation [11,12] but also for use within augmentation systems in the context of urban air mobility [13].…”

“…However, until today, no clear concept for future dual-frequency multiconstellation GBAS that provides improved performance compared to the current single-frequency single-constellation systems has been established. Two different options for the future GBAS system, which will support CAT III precision approaches and automatic landings, are under discussion: the GBAS Approach Service Type F (GAST F) concept being developed primarily through the Single European Sky ATM Research (SESAR) program in Europe [38,39], and the GBAS Approach Service Type X (GAST X) concept being developed primarily in the United States [40,41]. Both concepts propose to shift all responsibility for anomalous ionospheric gradient monitoring to the aircraft.…”
