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. 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.
