This notice informs the public that the Global Positioning System (GPS) Joint Program Office (JPO) will be hosting a technical working group meeting to discuss ICD-GPS-200 and IS-GPS-705. Changes to be discussed include:

(1) PIRN-200C-008, which deletes all Letters of Exception except for one, updates calendar year data requirement, clarifies applicable UTC/GPS-time relationships, toa and toe.

(2) Draft IS-GPS-200D and PPIRN-705-001, which describe the Improved Clock and Ephemeris (ICE) message on L2C and L5. The ICE message is the new GPS nav data that will replace the current clock and ephemeris data as indicated in section 30.3.2 of current ICD-GPS-200C.

The meeting will also address those deferred comments from the previous ICWG review of IS-GPS-705.
