SUMMARY:Seminar: Satellite Positioning in Our Uncertain World
DESCRIPTION:\nSatellite positioning is one of the basic needs of our modern society. There are a vast number of applications that millions of people use every day. Four systems, including GPS and Galileo, are collectively known as the GNSS (Global Navigation Satellite Systems). The infrastructure enabling GNSS positioning is mostly invisible to the user. This includes the navigation satellites, their signals and signal processing, geodetic reference frames, and ground-based geodetic networks that enable the precise use of GNSS positioning.\n\n\n\nIn recent years, we have seen an increasing number of cases where GNSS positioning has been disturbed, either intentionally or for natural reasons. In this seminar, we will discuss the threats and vulnerabilities of GNSS positioning and ways to detect and mitigate them. Welcome to hear and discuss the topic.\n\n\n\n\n\n\n\nTime: Wednesday, 18 September 2024, 16:00-19:00\n\n\n\nVenue: Finnish Academy of Science and Letters (Mariankatu 5 A, 2nd floor, Helsinki)\n\n\n\nOrganizer: Group of Geosciences, Finnish Academy of Science and Letters\n\n\n\nPre-registration: by 16 September: electronic form ( https://acadsci.fi/en/news/events/seminar-satellite-positioning-in-our-uncertain-world-18-9-2024-2/#registration-eng ) (please see below) or emilia.lahde@acadsci.fi / 050 512 8830\n\n\n\nThe seminar is open to the public, welcome! The attendance capacity is for 40 participants. The seminar will be held in English. Coffee and snacks are provided.\n\n\n\nProgramme\n\n\n\nOpeningPetri Pellikka, Professor, University of Helsinki, Earth Change Observation Lab\n\n\n\nGlobal Navigation Satellite Systems: yesterday, now, tomorrowMarkku Poutanen, Professor emeritus, Finnish Geospatial Research Institute FGI of the National Land Survey\n\n\n\nPrinciples and performance of network RTK (real-time kinematic) GNSS positioning: case active ionosphereHannu Koivula, Professor, Finnish Geospatial Research Institute FGI of the National Land Survey\n\n\n\nProtecting GNSS from intentional interferenceLaura Ruotsalainen, Professor, University of Helsinki, Department of Computer Science\n\n\n\nTopographic influences on GNSS jamming signalsHanna Lahtinen, MSc, University of Helsinki, Department of Geosciences and Geography\n\n\n\nIndoor Positioning Using Acoustic SignalsRuizhi Chen, Professor, Wuhan University, Director of the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing\n
