Japan MSAS GBAS Update GIPTA

Scope of this source note

This source note captures a GIPTA document or closely related document cluster for provenance and downstream claim control.

Primary document or cluster:

  • Download-20260414152729/Day1_1430 MSAS GBAS Update in Japan_GIPTA2.0.pdf

Supported claims currently usable in the vault

  • The source describes GBAS benefits and Japan implementation, including Haneda GLS CAT-I trial availability since July 2020 and full-scale operation from 23 January 2025, plus MSAS/SBAS implementation status and procedure/airport counts.

Boundary and uncertainty

  • Use as a comparator source for ASEAN lessons; confirm latest operational numbers from JCAB/official publications before treating them as current.
  • This is a source scaffold built from local extracted text; exact publication metadata, version control, and official public availability may still need confirmation.

Downstream use

Use this note to support narrow GIPTA-derived claims in ASEAN implementation, testbed, governance, operation, or country notes. Do not use it to restate generic SBAS definitions already covered by SBAS-Terminology, SBAS Integrity, Protection Levels, or Alert Limits.
