  1. IS-GNSS 2014 Jeju, South Korea Oct. 22, 2014 MSAS Status Takeyasu Sakai Electronic Navigation Research Institute, Japan

  2. Contents • Current Status • MSAS User Segment & PBN • LPV Approach Trial • R&D for Performance Improvement

  3. Current 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 through 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.

  4. MTSAT-1R MTSAT-2 GPS Satellites Ranging Signals Augmentation Signals 6 GMS in Japan Hawaii MRS Sapporo GMS Users Kobe MCS (and GMS) Fukuoka GMS Canberra MRS Hitachi-Ota MCS (and GMS) Tokyo GMS Ground Network Hawaii MRS Naha GMS Australia MRS Configuration MSAS Monitor Stations • 2 GEO, 2 MCS (Master Control Station), 4 GMS (Ground Monitor Station), and 2 MRS; • MCS also has GMS function; MSAS has 6 domestic monitor stations. • 2 MRS (Monitor and Ranging Station) for GEO positioning for GEO ranging function.

  5. MSAS GEO (MTSAT) MTSAT-1R Spacecraft • 3-axis stabilized spacecraft with the standard bus system. • Solar panel at the single side. • Due to installation of equipment for the weather mission. • L-band transponder with the bandwidth of 2.2MHz. • Uplink: Ku-band (13GHz) due to results of frequency coordination. • Also has downlink channel in Ku-band. • For power control of uplink signal because of rain attenuation in Ku-band.

  6. MCS Facilities KASC (Kobe Aeronautical Satellite Center) HASC (Hitachi-Ota Aeronautical Satellite Center) • Western part of Japan • MCS nominal for MTSAT-1R (PRN129) • Backup for MTSAT-2 (PRN137) • Dishes for 2 GEO and emergency • Eastern part of Japan • MCS nominal for MTSAT-2 (PRN137) • Backup for MTSAT-1R (PRN129) • Dishes for 2 GEO

  13. LPV Approach Trial Flight Inspection Aircraft of JCAB Gulfstream-IV JA001G / JA002G SAAB 2000 JA003G / JA004G Bombardier BD-700 JA005G / JA006G Bombardier DHC-8-300 JA007G Upgraded FMS to support SBAS LPV approach

  14. DHC-8 Upgraded for LPV MLS= MSAS Landing System? (They used I/F for MLS, micro-wave landing system) Announciator EADI EHSI

  15. Trial at Fukushima AP Database for LPV App = ILS Overlay at Fukushima, Niigata, Kouchi, Miho. On 16 July, 2010 Test Flight at Fukushima LPV Announciator ON HPL: 17.4m < HAL: 40m VPL: 31.3m < VAL: 50m GPS: 11 SV Start Approach Captain Side: LPV Co-Pilot Side: ILS EADI/EHSI indicate same as ILS Completed LPV Approach with MSAS !! Indicate ‘0.0NM’ over the runway threshold LPV Approach Chart for Test Flight （Fukushima Airport）

  16. Performance Improvement Motivation • 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.

  17. Performance Improvement Current MSAS Enhanced MSAS 08/1/17 APV-I Availability 6 GMS Planar Fit 08/1/17 LPV-200 Availability 16 GMS + New Ionospheric Algorithm • The simulation result showing possibilities to improve the performance of MSAS.

  18. Future Satellite Systems Decision Making Year MTSAT-1R Operation Single satellite operation term MTSAT-2 Operation 4-year life extension Near-Term Outlook: Current Plan MSAS Commission • EoL of MTSAT-1R is forecasted as the end of 2014. • Expect the extension of EoL of MTSAT-2 for 4 years. • After EoL of MTSAT-1R, 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…

  19. 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-1R/MTSAT-2 GEOs. • End of life of the 2nd GEO is extended, but in 2020. • Currently discussing the plan beyond 2020. • Contact: sakai@enri.go.jp
