Request for Public Review and Comment of Changes to the Navstar GPS Space Segment/Navigation User Segment Interface Control Document (ICD)

This notice informs the public that the Global Positioning System (GPS) Joint Program Office (JPO) proposes to revise ICD-GPS-200, Navstar GPS Space Segment/Navigation User Interfaces. This proposal changes the document identifier from ICD-GPS-200 to Interface Specification (IS)-GPS-200. In addition, this revision will increment the revision letter from C to D, resulting in IS-GPS-200 Revision D. One of the main subjects of this revision effort is an introduction of new Improved Clock & Ephemeris (ICE) navigation message that will be broadcast with L2 C signal. These proposed changes are described in a Draft IS-GPS-200D, dated 9 July 2004. This draft document is an updated version of the draft document previously released in February 2004. The draft document can be viewed and downloaded at the following Web site: http://gps.losangeles.af.mil. Click on "System Engineering", then "Public Interface Control Working Group (ICWG)". Reviewers should save the document to a local memory location prior to opening and performing the review.
