Preeminence in PNT is a National Objective

• For the warfighter
• Global PNT has revolutionized military operations
  
• Reduced collateral damage (people,
  infrastructure)
• Limits friendly fire vulnerability
• Higher accuracy munitions
• Fewer sorties to accomplish mission needs
  (reduces exposure)
• Aircraft standoff capability minimizes exposure
  to highlydefended environments
• Enhanced warfighter situational awareness Blue
  Force tracking
• For the Nation and the World
• Global PNT has also significantly enhanced
  civilian life
• Air traffic control
• Commercial navigation
• Enable cellular communication
• Demand will continue to grow well beyond next
  decade

Saves Warfighter Lives

• Timing of critical financial transactions
• Wildland fire management
• Precision agriculture

GPS is essential for the conduct of any war and
an integral part of day-to-day life
