Dr. Charles L. Rino

charlesRino2014

Dr. Rino received his B.S. and M.S. degrees in Electrical Engineering from UC Berkeley in 1965 and 1966. He received his Ph.D. in Information and Computer Science from UC San Diego in 1970. His recent research interests have included: analysis of 4 years of high-resolution ionospheric density measurements from the C/NOFS satellite unseeing novel data segmentation and wavelet-based spectral classification,a novel configuration-space model for highly anisotropic structures, and development of a novel processing scheme for digital beacon satellite receivers. Most recently he has turned his attention to the GNSS satellite propagation diagnostics in association with Colorado State University Global Positioning Systems Laboratory at Fort Collins, Colorado. In 1989 he was elected IEEE Fellow for contributions in wave propagation and ionospheric physics. He is principal author on over 50 papers on ionospheric physics, radio propagation, and surface scatter.

Logan Scott

loganScott2016

Logan Scott has 35 years of military and civil GPS systems engineering experience. He is a consultant specializing in radio frequency signal processing and waveform design. At Texas Instruments, he pioneered approaches for building high-performance, jamming-resistant digital receivers. At Omnipoint (now T-Mobile), he developed spectrum sharing techniques that led to a Pioneer’s preference award from the FCC. He is a cofounder of Lonestar Aerospace, an advanced decision analytics company located in Texas. He has been an active advocate for improved civil GPS location assurance through test based GPS receiver certification, crowdsourced jammer detection and location, and by adding robust signal authentication features to civil GPS signals. He is a Fellow of the Institute of Navigation and holds 39 US patents.
