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 Signal Structure
-Compatibility & Interoperability achivement.
-Due to the fact that MTSAT signal are broadcast through the majority region of Asian/Pacific, and there are two MTSAT Monitor stations in Hawaii (USA) and Camberra (Australia), the MSAS service area could be easily expanded if more GMS stations would be installed in MTSAT coverage area.
