Talk Title: Beyond GPS: Engineering Resilient Location Systems
and Building the Company to Deliver Them
Abstract: Reliable location and timing are critical for both defense and commercial
applications. However, reliance on GPS and GNSS creates vulnerabilities—ranging from natural
signal denial in environments like indoors and underground to intentional threats such as
jamming and spoofing, which are increasingly prevalent worldwide. This talk explores the
journey of developing location and timing technologies that operate effectively without GPS or
GNSS.
Dr. Teolis will discuss the technical challenges of delivering accurate, resilient location solutions
through advanced sensor fusion and mapping algorithms, highlighting key innovations from TRX
Systems’ work in providing resilient location and mapping. Additionally, the presentation will
delve into the entrepreneurial journey of building a company dedicated to this mission—
navigating the complexities of technological innovation, securing funding, and meeting the
evolving demands of military and industrial users.
Bio: Carole Teolis earned dual B.S. degrees in electrical engineering
and mathematics, and master’s and doctorate degrees in electrical engineering from the
University of Maryland (UMD). She has dedicated her professional career to the pursuit of
engineering research and development that is both impactful and marketable.
Teolis co-founded TRX Systems as a Clark School Mtech Ventures incubator company and built
it into a successful commercial company, where she serves as its chief technology officer.
Under Teolis’ leadership, TRX has distinguished itself as an industry leader in developing
infrastructure-free, GPS-denied navigation and mapping solutions.
