  1. Observations & Recommendations National PNT Advisory Board

  2. Taskings • Recommend areas where GPS & its augmentations can be made more competitive • Recommend ways to promote and demonstrate current and future capabilities of GPS & its augmentations to the U.S. and international communities; • Assess technology & market trends as the number of worldwide GNSS providers increase.

  3. Recommendations to EXCOM • Remove Selective Ability from all future systems • Begin transmitting navigation message on L2C • Support for favorable EXCOM decision to designate eLORAN as back up to GPS • Place GPS III quickly under contract with early delivery • Take actions to maintain current level of GPS service

  4. Advisory Board themes for the next Administration • Maintain the policy for an open signal free of direct user charges • Seek to insure GPS remains the signal of first use • See International collaboration to that end • For users -- Insure transparency & stability in the evolution of GPS • Implement laser reflectors on future GPS • For National Security Infrastructure - Develop means to detect, measure, locate & mitigate radio interference/jamming

  5. Advisory Board wants to Thank you all for your support & the opportunity to serve

  6. Back Up

  7. Press Office U.S. Department of Homeland Security February 7, 2008 Contact: (202) 282-8010 STATEMENT FROM DHS PRESS SECRETARY LAURA KEEHHNER ON THE ADOPTION OF NATIONAL BACKUP SYSTEM TO GPS Today the U.S. Department of Homeland Security will begin implementing an independent national positioning, navigation and timing system that complements the Global Positioning System (GPS) in the event of an outage or disruption in service. The enhanced Loran, or eLoran, system will be a land-based, independent system and will mitigate any safety, security, or economic effects of a GPS outage or disruption. GPS is a satellite-based system widely used for positioning, navigation, and timing. The eLoran system will be an enhanced and modernized version of Loran-C, long used by mariners and aviators and originally developed for civil marine use in coastal areas. In addition to providing backup coverage, the signal strength and penetration capability of eLoran will provide support to first responders and other operators in environments that GPS cannot support, such as under heavy foliage, in some underground areas, and in dense high-rise structures. The system will use modernized transmitting stations and an upgraded network.
