Modern satellite navigation systems, their applications and vulnerabilities
in Autonomous Unmanned Aerial Vehicles and self driving cars.
When: May 31st, 2018, 6:00 pm – 8:30 pm
Dr. Pervan's research is focused on navigation and
sensing applications that simultaneously demand extremely high levels of
accuracy, integrity, and continuity. These include, for example navigation for
aircraft precision approach and landing, detect and avoid systems for unmanned
aerial vehicles (UAVs), and navigation of self-driving cars.
His team is heavily involved with GPS navigation systems and Inertial Navigation
Systems (INS) for both military and civil aviation. Some airports have enhanced
ground based GPS systems which provide highly accurate positioning of aircraft
on approach. His research looks at ways to detect and circumvent GPS spoofing
and GPS jamming. He has some good stories to tell on this topic.
An offshoot of the GPS integrity and continuity work is finding solutions to the
autonomous airborne refueling of ship launched drones, and then autonomously
landing them back on the ship. As the drone refuels, its view of the sky is
blocked by the tanker, so it loses its navigation awareness. Refueling takes
place with the tanker flying an oval pattern, which means that during the
process the drone experiences sequential blockages of the entire sky.
Accommodating these fix losses and safely maintaining formation with the tanker
requires sophisticated algorithms.
Dr. Pervan's group is also developing enhanced navigation techniques for
self-driving cars. He makes the point that on many of Chicago's streets, it is
impossible to pick up enough GPS signals at any time of the day due to the
patterns of the satellite orbits and the narrow sky view. Using lasers to
identify light poles and other terrestrial objects is fraught with difficulties
due to mis-identification and environmental conditions. They've taken an
interdisciplinary approach to the problem by teaming up with architects and
urban planners to re-envision what a street looks like and how to make the
navigation bullet proof—using trees!
