5 additional IIR-M satellites to launch Since Dec 93, U.S. Government met/exceeded
civil GPS service performance commitments SPS Performance Standard (PS)
U.S. DoD committed to superior GPS service
30 Healthy SatellitesBaseline Constellation: 24
GPS Constellation Status & Availabilityas of March 2007
as of 26 Mar 07

GPS Constellation Status & AvailabilityGrowing to 30+ Satellites
IIR-15(M) launched: Monday, 25 Sep 06 Set healthy: Thursday, 12 Oct 06, SVN 52 - PRN 31 17 days from launch to on-orbit ops
IIR-16(M) launched: Friday, 17 Nov 06 Set healthy: 13 Dec 06, SVN 58 - PRN 12
PRNs 12 & 32 return to ops –allows growth to 32 SV constellation
Larger constellation for improved availability & accuracy
PRN – Pseudo Random Noise (spreading code)SVN – Space Vehicle Number

Sustaining capabilities for military and civil users worldwide Maintain ground systems/on-orbit satellites, launch new satellites Fielding GPS enhancements, such as Legacy Accuracy Improvement
Modernizing constellation with new signals and capabilities First IIR-M launch Sep 05, first IIF launch 2008, first III launch 2013 New civil and military GPS signals Transitioning control segment from legacy to new architecture/system
by Summer ‘07 Continuing work with Galileo and international community
Developing next generation of GPS Acquisition strategies for space, ground, and user segments Synchronizing space, control, and user equipment upgrades “Back to Basics” focus and incremental block approach
Managing GPS systems & supporting stakeholders Technical baselines, interfaces, performance Supporting/participating in key fora – NPEC/NPCO, DSB, IRT, PNT FACADepartment of Defense and Air Force are committed to responsible stewardship of GPS as a global
