EventRegulatory Goal Realistic

Step

New Requirements - Geodetic

• Geodetic Requirements• Achieve a stable geodetic reference frame with an

accuracy at least ten times better than anticipated user requirements

• Maintain a close alignment of the WGS84 reference frame with the International Terrestrial Reference Frame

• Provide a quality assessment capability independent of current radiometric measurement used to determine GPS orbits and clock performance

• Ensure interoperability of GPS with other GNSSs through a common, independent measurement technique

Geodetic Requirements – Status

• Requirements and AoA submitted to IFOR - Apr 07• One GPS-based alternative (Satellite Laser Reflectors) with other

non-GPS alternatives• Sent out for review Apr 07

• No critical/substantive comments received

• Many favorable comments received

• IFOR letter to NASA approving Geodetic Requirements for inclusion in GPS IIIB CDD prior to entering JCIDS process – Aug 07• GPSW analysis had not been accomplished

• IFOR Requested GPSW review for GPS III satellite impacts• White papers provided in Jun 08 opposing implementation on SVs, but

also provided possible solutions

• Geodetic Requirements Working Group chartered by IFOR

Geodetic Requirements Working Group

• Intent is to fully explore all security, cost, and technical issues prior to entering the JCIDS process

• First meeting held 17 July 08• Attended by representatives from NASA, USGS, NRL,

NGA, DOT, USNO, SAF/USA, AF/A5R, GPSW, AFTAC and AFSPC/A5P

• Created roadmap to resolve issues

• Additional Technical Meeting held 26 Aug 08 to further explore technical issues

• Next meeting – Nov 08

Geodetic Approval Cycle

Send to IFOR For Review

GPSW Analysis &Comment Resolution

EnterJCIDSProcess

• Requirements submitted Apr 07• IFOR approval Aug 07

• Did not include GPSW analysis• GPSW analysis provided Jun 08• Currently working identified technical issues• Anticipated completion 1 Dec 08

Distress Alerting Satellite System (DASS)

• The United States Government, specifically the U.S. Coast Guard, Department of Defense, and the National Oceanic and Atmospheric Administration, requires an enduring space-based capability to detect, locate, and relay distress alerts from emergency beacons carried by aviators, mariners and land-based users to search and rescue services.

• The federal government requires a capability:• To support the general public• To support civilian SAR efforts of the USCG and DoD

worldwide• To support military SAR operations worldwide• To meet international obligations under the Chicago

Convention

DASS – Status

• Requirements and AoA received 28 Jul 08• Not a GPS or PNT requirement – would be a secondary

payload

• Package sent out for IFOR review 1 Aug 08, comments due 1 Oct 08• Letter supporting requirements received from Joint

Personnel Recovery Agency

• Comments received and being adjudicated

• GPSW performing cost and technical analysis• USAF Red Team conducting national security

analysis

Wrap Up

• Flexibility in the requirements development process is key – one size doesn’t fit all

• Geodetic and DASS requirements are being processed through the IFOR • Each has unique issues that require slightly different

handling
