Keys to the Global Success of GPS

• Program Stability and Performance

• Policy Stability and Transparency

• Private Sector Entrepreneurship and Investment

AIAA 09/09

The Global Positioning System

• Baseline 24 satellite constellation in medium earth orbit

• Global coverage, 24 hours a day, all weather conditions

• Satellites broadcast precise time and orbit information on L-band radio frequencies

• Two types of service:– Standard (free of direct user fees)

– Precise (U.S. and Allied military)

• Three segments: – Space

– Ground control

– User equipment

GPS Constellation Status

• 11 Block IIA• 12 Block IIR• 7 Block IIR-M• First Block IIF launch in spring

2010– 12 Block IIF satellites planned

• GPS continues to meet/exceed civil service performance commitments

30 Operational SatellitesAs of August 27, 2009 (Baseline Constellation: 24)

Block IIA/IIR Block IIIBlock IIR-M, IIF• Backward compatibility

• 4th civil signal (L1C)• Increased accuracy• Increased anti-jam power

• Assured availability• Navigation surety• Controlled integrity• Increased security• System survivability

IIR-M: IIA/IIR capabilities plus• 2nd civil signal (L2C)•M-Code (L1M & L2M)

IIF: IIR-M capability plus• 3rd civil signal (L5)• Anti-jam flex power

Basic GPS• Standard Service– Single frequency (L1)– Coarse acquisition

(C/A) code navigation• Precise Service– Y-Code (L1Y & L2Y)– Y-Code navigation

Increasing System Capabilities Increasing Defense / Civil Benefit

GPS Modernization Program

AIAA 09/09

Benefits of GPS Modernization

System-wide improvements to meet increasing civil, commercial, and military demands•Higher standalone performance, accuracy, etc. •More robust against interference •Improved indoor, mobile, and urban use•Provides separate more secure military signal•Interoperability with other Global Navigation Satellite Systems

AIAA 09/09

GPS III Update

• Contract for GPS III-A satellites awarded, May 2008– Selective Availability feature

eliminated

• Contracts for Next-Generation Operational Control Segment (OCX) awarded, Nov 2007– Will implement full functionality of

L2C and L5

• Future increments of GPS III will incorporate additional capabilities– As technology matures and new

requirements are validated8

U.S. Space-Based PNT Policy

GOAL: Ensure the U.S. maintains space-based positioning, navigation and timing services, augmentation, back-up, and service denial

capabilities that…

ASSURE SERVICE Provide uninterrupted availability of PNT services

MEET DEMANDSMeet growing national, homeland, economic security, and civil requirements, and scientific and commercial demands

LEAD MILITARILY Remain the pre-eminent military space-based PNT service

STAY COMPETITIVEContinue to provide civil services that exceed or are competitive with foreign civil space-based PNT services and augmentation systems

INTEGRATE GLOBALLY Remain essential components of internationally accepted PNT services

LEAD TECHNICALLYPromote U.S. technological leadership in applications involving space-based PNT services
