The Space Force hosted the 2023 Public Interface Control Working Group and Open Forum for the following documents:

This meeting was open to the general public where public participation was welcomed.

The purpose of this meeting was 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 (as defined in ICD-GPS-870). The new products include the GPS Advisory, GPS Advisory Collection, Ops Status, and the Public Common Almanac.

The meeting also presented a conversion tool and other information necessary for GPS users to access the new product(s) and ensure backwards compatibility.
