Logan Scott has over 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 is also a partner at GeoCodex LLC developing location aware security architectures for mobile applications. Logan 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. Logan is a Fellow of the Institute of Navigation and holds 38 US patents.
Approaches for Resilient Positioning, Navigation and Timing
Diverse elements of our military capability and national infrastructure are critically reliant on GPS as a near “sole means” source for precise location and time. Yet, GPS signal reception is potentially vulnerable to interference, and, it does not work well in many environments; for example indoors where people spend most of their time. Resilient “anywhere, anytime” position and timing will entail using a system of systems, not just a particular system.
The discussion starts with a quick review of how pervasive GPS has become and then describes some of the unmet needs and vulnerabilities. This webinar then surveys some of the alternate approaches currently being fielded and under development with an eye towards their strengths, weaknesses, and synergisms in differing environments and applications. In the course of the webinar, other timing and location systems surveyed will include: other SATNAV systems such as Glonass, Galileo and Beidou; eLoran/VLF; Locata’s position and time system; WiFi positioning; select LTE/4G capabilities; Pedestrian Dead Reckoning (PDR); the P1588 precision clock synchronization protocol; and Chip Scale Atomic Clock (CSAC) developments. The importance of maintaining situational awareness for establishing environmental context is examined. Different system/sensor combinations shine in different environments but only if correctly matched to the environment.
