Using a Wide Area Receiver Network to Support GBAS Ionospheric Monitoring

Abstract: BIOGRAPHIES 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 communications. The same year she joined the German Aerospace Center where she is working on the impact of ionospheric irregularities in the single-frequency single-constellation GBAS. Daniel Gerbeth received a Bachelor and Master's degree in Electrical Engineering and Information Technology from Karl… Show more

“…The rate of false alarms, higher than desired, is problematic in GAST D while applying the same monitoring thresholds derived for mid-latitudes to regions in which the active ionosphere is not well represented with the mid-latitude ionospheric threat model [7]. For that reason, in [10], we proposed a real-time ionospheric monitoring concept that includes external information about the state of the ionosphere in GBAS instead of always relying on worst case models. Our proposed monitor provides protection to all GBAS users by using a wide area network of dual-frequency and multi-constellation GNSS stations situated in carefully surveyed locations.…”

“…While trying to adapt the GAST D concept to other regions with more severe ionospheric conditions, the previously mentioned issues could have a negative impact on GBAS availability [9]. In previous work [10], we proposed a real-time ionospheric monitoring approach that could reduce the conservative assumptions currently applied in GAST C and D and thus improve their availability under active ionospheric conditions. Moreover, we described how the monitor could work under nominal conditions and evaluated the impact of noise and multipath on the monitoring concept.…”

“…In this paper, we build on Caamano et al. (2017) to propose an algorithm that addresses the detection of ionospheric gradients in real time and estimates the gradient parameters in near real time. Furthermore, we evaluate our algorithm with simulated ionospheric gradients, assessing the differences between the known simulated gradient parameters and the parameters estimated by our algorithm.…”
