Primary PNT Gaps
• Gaps primarily drawn from military’s PNT Joint Capabilities Document, with additions and modifications from parallel civil community documents and discussions– Operations in Physically Impeded Environments
– Operations in Electromagnetically Impeded Environments
– Higher accuracy with integrity
– Notification of Hazardously Misleading Info (Integrity)
– High Altitude/Space Position and Orientation
– Geospatial information - access to improved GIS data (regarding intended path of travel)
– Insufficient modeling capability

Vision
• Based on a foundation of national policy
• Efficiently develop and field the best technologies and systems (e.g. cost, schedule, acceptable risks, user impact)
• Promulgate stable policies (commitment to funding, commitment toperformance, advanced notice of change, etc)
• Foster innovation through competition within the commercial sector
• Ensure robust and enduring inter-agency coordination and cooperation
• Maximize the practical use of military, civil, commercial and foreign systems and technologies
• Judiciously develop and apply standards and best practices

Strategy
• Recommendations– Maintain GPS as a cornerstone of the National PNT Architecture
– Monitor PNT signals to verify service levels, observe environmental effects, detect anomalies, and identify signal interference for near real-time dissemination
– Transition or divest US GNSS augmentation assets that are unnecessarily redundant after capability is available from GPS modernization or other methods
– Continue to investigate methods to provide high-accuracy-with-integrity solutions for safety-of-life applications
– Develop a national approach to protect military PNT advantage

UNCLASSIFIED
Vector: Multiple Phenomenologies
• Recommendations– Encourage appropriate development and employment of equipment that
integrates information from diverse sources and information paths
– Assess the potential for the use of foreign PNT systems for safety-of-life applications and critical infrastructure users and, as appropriate, develop clear standards and criteria for their use
– Continue military PNT exclusive use policy while studying development of capabilities to enable military use of other signals
– Promote standards for PNT pseudolites and beacons to facilitate interchangeability and avoid interference
– Study evolution of space-based and terrestrial PNT capabilities to support diversity in PNT sources and information paths
– Ensure critical infrastructure precise time and time interval users have access to and take advantage of multiple available sources
111 Use Multiple Phenomenologies to the Maximum Extent Practical to Ensure Robust Availability

UNCLASSIFIED
Vector: Interchangeable Solutions
• Recommendations– Use participation in international PNT-related activities to promote
the interchangeability of PNT sources while assuring compatibility
– Evolve standards, calibration techniques, and reference frames to support future accuracy and integrity needs
– Identify and develop common standards that meet users’ needs forPNT information exchange, assurance and protection
– Establish common standards that meet users’ needs for the depiction of position information for local and regional operations

Vector: Cooperative Organizational Structures
• Recommendations– Develop a national PNT coordination process
– Identify and leverage centers of excellence for PNT phenomenology and applications
– Define, develop, sustain, and manage a PNT modeling and simulation core analytical framework
