DON'T MISS NEXT WEEK'S AOC VIRTUAL SERIES: Approaches for Resilient Positioning, Navigation and Timing (PNT), October 15
October 15, 2015 | 1400-1500 EDT (1800-1900 GMT)
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 toward 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.
