Diy gps signal jammer - portable signal jammer for gps navigation

The White House Office of Science and Technology Policy is asking for ideas on what technology to research to protect GPS. The research and development dollars are earmarked for projects that minimize or eliminate disruption to critical infrastructure from intentional and unintentional interference. The “Notice of Request for Information on Positioning, Navigation, and Timing Resilience” was issued Aug. 10 in the Federal Register. The office is seeking input “from all interested parties on the development of a National Research and Development Plan for Positioning, Navigation, and Timing (PNT) Resilience. “The plan will focus on the research and development (R&D) and pilot testing needed to develop additional PNT systems and services that are resilient to interference and manipulation and that are not dependent upon global navigation satellite systems (GNSS). “The plan will also include approaches to integrate and use multiple PNT services for enhancing resilience,” the RFI states. The effort is specifically headed by the Subcommittee on Resilience Science and Technology (SRST.) “The input received on these topics will assist the subcommittee in developing recommendations for prioritization of R&D activities,” the RFI states. Deadline for comments is 11:59 pm ET on Sept. 9. Responses should be submitted via email to PNTresearch@ostp.eop.gov — include “RFI Response: PNT Resilience” in the subject line of the message.
