Our Recommendations: GPS & GNSS Navigation and Timing

Protect, Toughen, Augment*

Protect GPS/GNSS

  • Recognize PNT as critical infrastructure
  • Designate and empower a lead federal official
  • Protect the adjacent bands to GNSS as “Quiet” neighborhoods
  • Make ownership of jammers a misdemeanor
  • Make use of jammers a felony
  • Make anti-jamming and anti-spoofing laws enforceable at all levels of government
  • Establish a national system to detect & rapidly locate jamming
  • Ensure sufficient enforcement personnel to detect, prevent, respond to and prosecute jamming

Toughen Receivers & Users

  • Develop standards for jam-resistant receivers to include ARAIM and RAIM
  • Establish as an industry best practice having more than one source of precise Position, Navigation and Timing (PNT) for critical infrastructure
  • For critical infrastructure that uses space-based PNT, establish as an industry best practice being able to continue normal operations in the event of an extended GNSS service disruption.

Augment GPS/GNSS Services

  • Provide a wide-area, difficult to disrupt, diverse non-space PNT service (GPS-Earth/eLoran)
  • Develop standards for seamless use with space-based PNT
  • Encourage development of numerous, complementary terrestrial PNT services to increase resilience (integrated radar, local positioning systems, inertial, etc.)
