Current StatusCurrent Status MSAS: Japanese SBAS in operation.
– MTSAT Satellite-based Augmentation System.– Operational since Sept. 27, 2007.
• Test signal since summer 2005.
– Continue stable operation with 2 GEOs.
Service for Air Navigation– GPS Augmentation Information for RNAV, from En-route th
rough NPA (RNP 0.3). Within Fukuoka FIR. Horizontal navigation only due to ionosphere.
– NOTAM is available to MSAS users. Alert for Service Interruption. Alert for Predicted Service Outage.

Performance ImprovementPerformance Improvement
• Provide Vertical Guidance– APV-I (LPV) or hopefully CAT-I (LPV200) performance.
• Hardware and Software Upgrade – Addition of up to 10 Ground Monitor Stations.– Installation of new algorithm developed by the ENRI.
The current system uses the algorithm same as IOC WAAS.The algorithm should be improved to adapt to the Japanese
ionosphere conditions which are more severe than U.S. and mitigate ionosphere effect.
