Recently, various research and publications across the globe are pointing out the rising trend of Software Defined Architecture for GNSS. Software Defined Radios (SDRs) are allowing a quick and simple implementation of wireless receiving and transmitting systems by combining the power of Digital Signal Processing (DSP) with the flexibility of programmable hardware.
Over the last few years, many crucial improvements occurred around this next-gen technology through the combination with open-source capabilities and even Graphics Processing Units (GPUs).
As a result of this innovation, some very powerful devices emerging including GNSS receivers and PNT (Positioning, Navigation and Timing) test & simulation solutions.
During this webinar, each speaker will examine some of the work being done by the organizations leading the way on this migration to a software defined architecture.
Lisa Perdue is a world-leading expert in testing critical GPS and GNSS systems. She has trained hundreds of engineers and technicians who are responsible for high-reliability positioning, navigation and timing (PNT) applications. She took a lead role in the development of the first GNSS Vulnerability Test System and speaks widely on the topic at many industry conferences.
As the Product Line Director at Orolia, Lisa directs the organization’s GNSS simulation activities and contributing to its entire portfolio of Resilient PNT solutions. She has more than 15 years of navigation and RF systems experience, which includes 10 years of service with the U.S. Navy, where she was a certified master training specialist.
M. Zahidul H. Bhuiyan is a Research Professor at the Department of Navigation and Positioning in Finnish Geospatial Research Institute. His main research interests include multi-GNSS receiver development, PNT robustness and resilience, seamless positioning, etc. He is actively involved in teaching GNSS related courses in Finnish universities and other training schools. He has been also working as a Technical Expert for the EU Agency for the Space Program (EUSPA) in H2020 project reviewing and proposal evaluation.
John Fischer has been part of Orolia for more than 15 years. He works with global navigation satellite systems, wireless, positioning navigation and timing, as well as specialized systems for its customers. Prior to joining Orolia, he specialized in wireless telecom as a founding member of two startups: Aria Wireless in 1990 and Clearwire Technologies in 1997. At Clearwire, he served as chief technology officer in creating wireless broadband equipment for internet connectivity. Early in his career, Fischer worked as a systems engineer in radar, EW, and command and control systems at Sierra Research and Comptek Research. He holds master’s and bachelor’s degrees in electrical engineering and computing engineering from the State University of New York at Buffalo.
