Working Group 4B: Network Timing Single Source Risk Reduction Status Update March 2016 Jennifer A. Manner, Chair
WP 4B Completed PROBLEM IDENTIFICATION: Reasons for failure temporary or long term: Solar flares or other disturbances Space Weather phenomena RF interference episodes Failure of upstream time sources whether deliberate or accidental Accidental or deliberate jamming Spoofing REQUIRED CHARACTERISTICS: Redundancy Independence from RNSS Increased Reliability Appropriate level of accuracy for the application 2
WG4B Finalizing We are finalizing for June the options that are available for a network timing back up solution to GPS, including the pros and cons of such options. These include, but are not limited to: eLoran Alternative RNSS systems Use of MSS systems Commercial RF distribution Sync over fiber And many others We are identifying both current, planned and future technologies that can serve as a viable solutions 3
WG4B Next Step: Recommendations We are working on determining recommendations to network timing alternatives for consideration in late 2016. 4
