IS-GNSS Oct. 2014 - Slide 15 Performance Improvement Motivation • Provide Vertical Guidance – APV-I (LPV) or hopefully CAT-I (LPV 200) performance. • Hardware and Software Upgrade – Addition of up to 10 Ground Monitor Stations. – Installation of new algorithm developed by the ENRI. ü The current system uses the algorithm same as IOC WAAS. ü The algorithm should be improved to adapt to the Japanese ionosphere conditions which are more severe than U. S. and mitigate ionosphere effect.

L of MTSAT-1 R is forecasted as the end of 2014. • Expect the extension of Eo. L of MTSAT-2 for 4 years. • After Eo. L of MTSAT-1 R, MSAS will be operated with 1 GEO. – Both KASC and HASC will operate with MTSAT-2. • Discussion on a successor to MSAS is ongoing: Other GEO project…

IS-GNSS Oct. 2014 - Slide 18 Conclusion • MSAS has been operational since Sept. 2007. – – – An operational SBAS in accordance with ICAO standards. Stable operation with two GEOs and two MCSs. Continue to serve with Enroute to NPA performance. • MSAS GEO: – Currently operating with MTSAT-1 R/MTSAT-2 GEOs. – End of life of the 2 nd GEO is extended, but in 2020. – Currently discussing the plan beyond 2020. • Contact: sakai@enri. go. jp
