The Navigation Center posted a notice to its website that the Global Positioning Systems Directorate will propose a change to the Navstar GPS Control Segment to User Support Community Interfaces (ICD-GPS-870), Interface Control Documents that will remove Section One from the GPS Operational Advisory.

If that change is approved, the plane/slot, SVN/PRN, Block Type, and Clock information will no longer be available on NAVCEN’s GPS Constellation webpage. This would occur in conjunction with the shift from the current ground control system to the Next Generation Operational Control System (OCX). Active NANUs will continue to be available. Users of the Operational Advisory message, or the Section 1 information contained within the message on NAVCEN’s GPS Constellation webpage, are requested to submit a comment using the “Contact Us” link to help NAVCEN understand how the loss of this information would impact operations. The CGSIC will compile responses from the community and provide them to the GPS Directorate in advance of the next GPS Public Interface Control Working Group.
