Notice of Meeting—Public Interface Control Working Group (ICWG) for Signals-in-Space (SiS) Documents (IS-GPS-200E, IS-GPS-705A, IS-GPS-800A).


The United States Air Force published a meeting notice on the Public Interface Control Group (ICWG) on June 2, 2011 Vol. 76, No. 106. Due to scheduling conflicts, the meeting has been rescheduled to September 13-15, 2011. This amended notice informs the public that the Global Positioning Systems Directorate (GPSD) will be hosting a Public Interface Control Working Group (ICWG) meeting for the NAVSTAR GPS public signals in space (SiS) documents; IS-GPS-200 (Navigation User Interfaces), IS-GPS-705 (User Segment L5 Interfaces), and IS-GPS-800 (User Segment L1C Interface). The purpose of this meeting will be twofold: (1) to resolve the comments against the public signals in space (SiS) documents with respect to the seven issues outlined below, and (2) to collect issues/comments outside the scope of the issues outlined below for analysis and possible integration into the following release.

The ICWG is open to the general public. For those who would like to attend and participate in this ICWG meeting, we request that you register no later than 11 Jul 2011. Please send the registration to and provide your name, organization, telephone number, address, and country of citizenship.

  • Pseudorandom Noise (PRN) Expansion.
  • User Range Accuracy (URA) Definition.
  • Almanac Intervals.
  • Pseudorange Parameters.

Comments outside the scope of the above issues will be collected, catalogued, and discussed during the public ICWG as potential inclusions to the version following this release. If accepted, these changes will be processed through the formal Directorate change process for IS-GPS-200, IS-GPS-705, and IS-GPS-800.
