**SUPPLEMENTARY INFORMATION:**
The purpose of this meeting is to update the public on proposed GPS public document changes, collect issues/comments for analysis and adjudicate subject comments for possible incorporation into future GPS public document revisions. When OCX is fielded, the current (5) plain text data products (as defined in ICD-GPS-240) will be replaced by (4) XML based data products. These products include the GPS Advisory, GPS Advisory Collection, Ops Status, and the Public Common Almanac. The subject meeting will also present a conversion tool and other information necessary for GPS users to access the new product formats and ensure backwards compatibility. The out-of-cycle 2023 Public Interface Control Working Group is open to the general public.
Comments to the proposed changes will be collected, catalogued, and adjudicated for potential inclusion. If accepted, these changes will be processed through the government change management process for ICD-GPS-870. All comments must be submitted in a Comments Resolution Matrix. This form along with the proposed change notices, public document baseline documents and the official meeting notice are posted at: *https://www.gps.gov/technical/icwg/meetings/2023/06/.*
Please submit comments to the Space Systems Command GPS Requirements Section (SSC/CGEPR) workflow at *[email protected]* by April 12, 2023. For those who would like to attend and participate, we request that you register no later than May 10, 2023. Please send the registration information to *[email protected],* providing your name, organization, telephone number, email address, and country of citizenship.
