Abstract
One of the most important tasks of modern navigation systems is accurate determination of vehicle position in airspace. Nowadays Global Navigation Satellite Systems are considered as the primary means of positioning and navigation in the airspace, due to its high accuracy, continuity and availability on a global scale. However, today, the operation of GNSS is connected with the threat of jamming and interference of navigation signals, that can affect the safety of aviation. The question of aircraft location determination is especially important during takeoff and landing phases, because the accuracy and availability of positioning are closely connected with the safety of aviation. This talk will be based on scholar research on development of advanced methods of Alternative Positioning, Navigation and Timing, in particular methods of positioning using multiple navigational aids with data prediction and regression analysis; data from Traffic Collision Avoidance System and ADS-B messages; passive DME signals.

Bio
Ivan Ostroumov has been a Fulbright scholar in the school of Aeronautics and Astronautics at Purdue since September 2017. He obtained his PhD degree of Engineering in Navigation and Traffic Control in 2009 from National Aviation University of Ukraine. Since then, he has been a research scientist and associated professor for National Aviation University. Since 2016 he has also served as navigation instructor at “Aviation Company Ukrainian Helicopters”. Also, he took part in several projects, including: Supporting SESAR on GNSS Vulnerability Assessment by performing Space Weather Analysis (Navigation department, EUROCONTROL, Brussel) and E-learning course development (Institute of Air Navigation Services, EUROCONTROL, Luxembourg). His research theme is advanced methods for Alternative Positioning, Navigation, and Timing. Current research projects include: Methods and Algorithms of positioning by multiple navigational aids, Availability and Accuracy estimation of navigation.
