(*) The trial service of MADOCA-PPP will start in September 30th, 2022. The operational service of MADOCA-PPP will start in April 1st, 2024. For Signal Authentication Service, trial signal transmission is planned for July 2023 and operational service is planned to start in April 2024. Signal Authentication Service will be covered later in Performance Standard.
(**) IS-QZSS-SAS-001-Draft-002 is a draft version. 
(***) 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.

(Draft, February 2022
/ PDF: 187KB)
As a demonstration, the wide-range ionospheric correction
for the Asia and Oceania regions is transmitted by the L6D
messeges to shorten the TTFF (Timi To First Fix) of
MADOCA-PPP. This document describes the reference
information of this demonstration.
