National Space Policy Secretariat, Cabinet Office 

To improve the security of GNSS signals, Cabinet Office is now developing ‘signal authentication service’ that can be used to prevent GNSS spoofing. This service is planned to transmit signals as a trial in July 2023 and become operational in April 2024.

Prior to the start of the trial transmission, the draft version of the user interface specification (IS-QZSS-SAS-001-Draft-002) is released.
