The Multi-functional Satellite Augmentation System (MSAS) is the Japanese SBAS System: a GPS Augmentation system with the goal of improving its accuracy, integrity, and availability, and that uses the Multifunctional Transport Satellites (MTSAT) owned and operated by the Japanese Ministry of Land, Infrastructure and Transport and the Japan Meteorological Agency (JMA). Tests had been accomplished successfully, and MSAS for aviation use was commissioned on September 27, 2007.[1]

MSAS receives GPS signal at the Ground Monitor Stations and the Monitor & Ranging Stations, checks operational status of GPS, analyze GPS error and ionospheric delay, and then broadcasts augmentation information through MTSAT (Multi-functional Transport Satellite)[2] from the Master Control Stations. Those satellites, MTSAT, broadcast the correction messages back to Earth, where MSAS-enabled GPS receivers use the corrections while computing their positions to improve accuracy.

MSAS Performances

MSAS for aviation use was commissioned on September 27, 2007. MSAS provide service for air navigation:

– 24hours a day, 7days a week

– Operational Information is provided as NOTAM (Service Interruption, degradation of service).

– Use for En-route through Non Precision Approach phase of flight (Performance improvement plan under development)-
