    Towards a Comprehensive Approach for Obtaining Resilient PNT

    Precise positioning and timing is becoming ever more deeply embedded into worldwide critical infrastructure. In the civil domain, numerous attacks have already been seen and the sophistication of attacks is growing. A layered defense with flexible responses provides the best hope for meeting the challenges of maintaining required navigation performance under adverse conditions. 
    No single defense or offense, no matter how good, is capable of dealing with all threats.
    A comprehensive and integrated civil policy is needed that takes into account the nature of the threats, their motivations, their likely evolution, and the costs and approaches for mitigating them. This talk explores not only the technical countermeasures available to civil users but also the legal and social engineering approaches that can militate against jamming and spoofing. The importance of penetration testing is illustrated via real-world examples (e.g. Portland) of what happens when receivers meet a threat for the first time. It is found that effective strategies for civil applications are fundamentally different from those suitable for military applications. Specific and actionable recommendations at the policy, receiver and systems level will be made.


    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 has been active in making national policy recommendations for civil receiver certification, jammer detection and location, spectrum protection, and cryptographic civil GNSS watermarking features. He is a cofounder of Lonestar Aerospace, an advanced decision analytics company located in Texas. Logan is a Fellow of the Institute of Navigation, a Senior Member of the IEEE, and holds 41 US patents.
