The MTSAT Satellite Augmentation System (MSAS) is the Japanese Satellite Based Augmentation System (SBAS) System:[1] a GPS Augmentation system with the goal of improving its accuracy, integrity, and availability.

First tests were accomplished successfully, and MSAS system for aviation use was declared operational in September 27, 2007,[2][3][4] providing a service of horizontal guidance for En-route through Non-Precision Approach.[1][2][5]

The SBAS signal used to be transmitted from MTSAT (Multi-functional Transport Satellites) operated by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT). The SBAS signal that is made by MLIT is now transmitted from the QZS-3 GEO satellite using the QZSS SBAS transmission service since April 2020.[6]


MSAS User Segment

The MSAS user segment is the GPS and SBAS-enabled receiver, which uses the information broadcast from each GPS satellite to determine its location and the current time, and receives the MSAS corrections from the MTSAT satellites. MSAS receivers design is identical to those designed for WAAS. Please refer to the article WAAS Receivers as well.

MSAS user equipment for civil aviation shall be compliant (certified) against several standards, e.g. RTCA MOPS DO 229 (see article SBAS Standards).
