“…Figure 6b shows the mean and standard deviation of the angle between the estimated and expected DOAs averaged over 60 snapshots. The satellite constellation is depicted from Figure 4b, where 7 Sats depicts the subset (1,3,6,8,9,10,17), 9 Sats depicts the subset (1,3,6,8,9,10,17,23,25) and 11 Sats includes all satellites. The performance with only 7 satellites in view is already very well with an error of only around 2 • .…”

“…It turns out that antenna calibration is still a major challenge. Therefore many research studies came up with so-called blind interference and / or spoofing countermeasures, that do not rely on calibration [1][2][3]. Although they are not complicated in terms of implementation and complexity and provide good results in most scenarios, they may degrade receiver performance by accidentally nullifying or attenuating authentic signals.…”

Soeren Zorn received his M.Sc. in electrical engineering from RWTH Aachen University in 2015. His bachelor and master thesis covered spoofing detection and mitigation. He is currently pursuing his Ph.D. at RWTH as a member of the Chair of Navigation. His research interests include multi antenna GNSS receivers, attitude and calibration estimation, robust interference and spoofing detection and mitigation. Michael Niestroj received his M.Sc. in electrical engineering from RWTH Aachen Universtiy in 2016. His master thesis covered attitude and calibration estimation for multi antenna GNSS receivers. He is currently prusuing his Ph.D. at RWTH Aachen University as a member of the chair of Navigation. His research is focused on calibration methods for GNSS multi antenna systems. Marius Brachvogel received his M.Sc. degree in electrical engineering from the RWTH Aachen University in 2016. Since then, he works as a research assistant for the Chair of Navigation. His current research includes GNSS interference and spoofing mitigation on distributed antenna systems. Stefano Caizzone rceived the M.Sc. in Telecommunications Engineering and the Ph.D. degree in Geoinformation from the University of Rome Toer Vergata, Italy, in 2009 and 2015, respectively. Since 2010, he is with the Antenna group of the Institute of Communications and Navigation of the German Aerospace Center (DLR), Wessling, Germany, where he is responsible for the development of innovative miniaturized antennas. His main research interests concern small antennas for RFIDs and satellite navigation, antenna arrays and grids with enhanced sensing capabilities, controlled radiation pattern antennas for robust satellite navigation and high-performance antenna design for precise satellite navigation. He is a participant of RTCA SC-159, active in the definition of minimum operational performance specifications for avionic GNSS equipment. Michael Meurer received the diploma in electrical engineering and the Ph.D. degree from the University of Kaiserslautern, Germany. After graduation, he joined the Research Group for Radio Communications at the Technical University of Kaiserslautern, Germany, as a senior key researcher, where he was involved in various international and national projects in the field of communications and navigation both as project coordinator and as technical contributor. From 2003 till 2013, Dr. Meurer was active as a senior lecturer and Associate Professor (PD) at the same university. Since 2006 Dr. Meurer is with the German Aerospace Centre (DLR), Institute of Communications and Navigation, where he is the director of the Department of Navigation and of the center of excellence for satellite navigation. In addition, since 2013 he is a professor of electrical engineering and director of the Chair of Navigation at the RWTH Aachen University. His current research interests include GNSS signals, GNSS receivers, interference and spoofing mitigation and navigation for safety-critical applications.
