Professor Kirsten Strandjord at ECE Spring 2024 Colloquium

Navigation in Challenged Environments

The lecture will present an overview of Professor Strandjord’s area of research in Global Positioning System (GPS) and Global Navigation Satellite System (GNSS) and Signal of Opportunity (SOP) technology and applications for positioning, navigation and timing (PNT). One of the primary lecture topics will highlight the challenges for positioning in urban environments and the algorithms and techniques studied to improve the use of these signals in this environment. Similarly, another topic of interest related to urban navigation is research that investigates the use of long-term evolution (LTE) signals, typically used for communication purposes, as signals of opportunity for navigation. Another GNSS-challenged environment will be presented related to navigating regions of space beyond the altitudes of GNSS constellation orbits and into cis-lunar space.
