(*) Signal Authentication Service will be covered later in Performance Standard.
In addition, there is no description for the Satellite Report for Disaster and Crisis Management (Extended Information) (DCX).
(**) IS-QZSS-SAS-001-Draft-002 is a draft version. IS-QZSS-SAS-001 will be released soon.
(***) IS-QZSS-MDC-002 includes the specification of ionospheric correction message, which is scheduled to be transmitted from QZS-6 and 7. Ionospheric correction transmission will start as the operational service after the experimental service. We will inform you of the specific schedule again.
