Also in the Receiver Section, IFEN multi-GNSS software receiver front-ends (FE) from IFEN GmbH, Poing, Germany, are used; the SX3 Dual-RF-FE (D-FE) and the SX3 Single-RF-FE (S-FE). In Positioning and Range Verifica- tion, the authors are referring specifical- ly to the MultiStation MS60 from Leica Geosystems, Heerbrugg, Switzerland. e GNSS receiver used in the Front- end Clock Synchronization section is the PolaRx4TR from Septentrio, Leuven, Belgium and Torrance, CA. T h e d r o n e r e f e r e n c e d i n t h e UAV sec t ion is t he DJ I Spread i ng Wings S1000+ Octocopter from DJI, Shenzhen, China. Acknowledgments and Disclaimer Acknowledgement should go to Gerhard Kestel, Stephan Ullrich, and Mathias Philips-Blum for their support during the measurement campaigns and their work setting up the testbed system. e project is self-funded by the Institute of Space Technology and Space Applica- tions of the "Universität der Bundeswehr München." The setup and the gained knowledge are and will be used for the DLR projects SatNavAuth (FKZ: 50 NA 1703) and NeedForPRS (FKZ: 50 NP 1708).

Since 2017 he has been a research associate at the Institute of Space Technology and Space Applica- tions of the "Universität der Bundeswehr München." His current research interests include GNSS signal generation, signal authentication, and signal per- formance analysis. Thomas Kraus graduated with a M.Sc. in Electrical Engineer- ing from the University of Darmstadt, Germany. In 2008, he joined the I nstitute of Space Technology and Space Applications of the "Univer- s i t ä t d e r B u n d e s w e h r München." He's been working as a research associ- ate on several projects of the German Space Agen- cy (DLR) and European Space Agency (ESA-ESTEC). His main research focus is on future receiver design offering a superior detection and mitigation capa- bility of intentional and unintentional interferences. Daniela Elizabeth Sánchez Morales studied Telematics Engineering at Instituto Tec- nológico Autónomo de Méxi- co (ITAM) in Mexico City. She also holds a Masters degree in satellite applications engi- neering from the Technical University Munich (TUM). She has been a research associate at the Institute of Space Technology and Space Applications (ISTA) since 2017. Her main research area is sensor fusion. Her current research focuses on LiDAR, sensor fusion between LiDAR and GNSS/INS, and relative and absolute naviga- tion algorithms particularly for terrestrial applica- tions. Ronny Blum received his Masters in Physics from the University of Basel, Switzerland. He then worked at Würth Elektronik in the field of signal transmission and later on at the Forest Research Institute in Freiburg im Breis- gau in the field of GNSS recep- tion within the forest. In 2017 he joined the University of Federal Armed Forces Munich, where he is working in the field of GNSS software receiv- er. Prof. Thomas Pany is with the Universität der Bundeswehr München at the faculty of aerospace engineering where he teaches satellite navigation. H i s re s e a rc h i n c l u d e s a l l aspects of navigation ranging from deep space navigation to new algorithms and assembly code optimiza- tion. Currently he focuses on GNSS signal process- ing for Galileo second generation, GNSS receiver design, and GNSS/INS/LiDAR/camera fusion. To support this activities, he is developing a modular GNSS test bed for advanced navigation research. Previously he worked for IFEN GmbH and IGASPIN GmbH and is the architect of the ipexSR and SX3 software receiver. He has around 200 publications including patents and one monography. Em. Univ.-Prof. Dr.-Ing. habil. Dr. h.c. Guenter W. Hein is Professor Emeritus of Excel- lence at the University FAF Munich. He was ESA Head of EGNOS & GNSS Evolution Pro- gramme Dept. between 2008 and 2014, in charge of devel- opment of the 2nd generation of EGNOS and Galileo. Prof. Hein is still organising the ESA/JRC International Summerschool on GNSS. He is the founder of the annual Munich Satellite Navigation Summit. Prof. Hein has more than 300 scientific and technical papers published, carried out more than 200 research projects and educated more than 70 Ph. D.´s. He received 2002 the prestigious Johannes Kepler Award for "sustained and significant contribu- tions to satellite navigation" of the US Institute of Navigation, the highest worldwide award in navi- gation given only to one individual each year. G. Hein became 2011 a Fellow of the US ION. The Technical University of Prague honoured his achievements in satellite navigation with a Doctor honoris causa in Jan. 2013. He is a member of the Executive Board of Munich Aerospace since 2016. Follow us on Twitter @insideGNSS
