Status of Japanese QZSS and SBAS Programs Agenda 9: Update on Satellite Constellations and Plans Status of Japanese QZSS and SBAS Programs Presented by: Takeyasu Sakai National Institute of Maritime, Port and Aviation Technology, Japan

Introduction QZSS (Quasi-Zenith Satellite System) Program Regional navigation service broadcast from high-elevation angle by a combination of three satellites on the inclined geosynchronous (quasi-zenith) orbit and a GEO. The first satellite “Michibiki” launched in 2010 has been continuously broadcasting GPS-like ranging signals and some augmentation signals. Begins the operation with 4-satellite constellation in April 2018, and 7-satellite constellation will follow in 2023. The mission of the operational QZSS: Positioning: Ranging and augmentation services including SBAS; and Messaging: Two-way mobile communication service for disaster and crisis management. MSAS: Japanese SBAS Service Operational since 2007 in accordance with the ICAO standards. Continues operation with MTSAT-2 GEO. Replacement to the fully new system and new GEO in 2020; Integrated to the QZSS program. Upgrade for vertical guidance likely in 2023 with the 2nd GEO.

Status of the QZSS Program Part I Status of the QZSS Program

QZSS Concept Broadcast signal from high elevation angle. GEO IGSOs QZSS-IGSO GPS/GEO Broadcast signal from high elevation angle. Applicable to navigation services for mountain area and urban canyon. Augmentation signal from the zenith could help users to acquire and augment other GNSS satellite signals at any time. IGSO (Inclined Geosynchronous Orbit) centered at 139E. Eccentricity 0.075, inclination 41deg. Additional GEO.

Mission Mission 1: Positioning Services Mission 2: Messaging Service Ranging Service: Broadcasts GPS-like ranging signals on three frequencies (L1C/A, L2C, L5I/Q, and L1C) to improve availability of navigation in urban and mountain areas. Submeter Level Augmentation Service: SLAS on L1S Code-phase differential correction service for mobile users. Centimeter Level Augmentation Service: CLAS on L6D Carrier-phase differential correction service for precision applications. Mission 2: Messaging Service Provides two-way mobile communication service for disaster and crisis management. Downlink short messages on L1 frequency. S-band two-way communication for emergency safety report. (C)JAXA QZSS Orbit and Ground Track

(Courtesy: (c) JAXA) Since June, 2011, QZSS have provided navigation signals with good qualities, satisfying with their performance specifications, continuously.

MSAS: Japanese SBAS Program Part II MSAS: Japanese SBAS Program

MSAS Program Beginning of SBAS Program in Japan: MSAS GEO Satellites: JCAB (Japan Civil Aviation Bureau) of Ministry of Land, Infrastructure, Transport and Tourism decided the development of its own SBAS in 1993. The system named MSAS, or MTSAT Satellite-based Augmentation System, was originally planned to be operational in 2000. MSAS GEO Satellites: MTSAT (Multi-functional Transport Satellite): Aviation and weather missions. MTSAT works for AMSS and SBAS services for aviation. Launch of the MTSAT-1 was unfortunately failed in 1999. Spare satellite: MTSAT-1R was launched in February 2005. 2nd GEO: MTSAT-2 on the orbit in February 2006. Ground facilities: Consists of 2 MCS (KASC and HASC), 6 GMS, and 2 MRS. Beginning Operation: Broadcast test signal since summer 2005. Finally, MSAS began its operation in September 27, 2007 after certification.

Current Status MSAS: Japanese SBAS in operation. (c) Mitsubishi Electric Corp. MSAS GEO: MTSAT-2 MSAS: Japanese SBAS in operation. Operational since Sept. 27, 2007. Continue operation with 2 signals via 1 GEO. MTSAT-1R decommissioned in Dec. 2015. Hawaii and Australia MRS sites are removed in Feb. 2015. Service for Air Navigation GPS Augmentation Information for RNAV, from En-route through NPA (RNP 0.3 performance). Within Fukuoka FIR. Only horizontal navigation due to ionosphere activities. NOTAM is available to MSAS users. Alert for Service Interruption. Alert for Predicted Service Outage. Expanding Users Most small/regional jets equip SBAS-capable avionics. Japanese new regional jet, MRJ will also be capable of SBAS. MRJ (Courtesy: MHI)

Continuous Operation Current status: Replacement in 2020: MTSAT-1R decommissioned in 2015. MTSAT-2 will be in 2020. 2 MRS sites removed in 2015. The ground facilities need to be upgraded: It is difficult to maintain 20-year old equipment. Replacement in 2020: MSAS V1 continues operation with a GEO (MTSAT-2) and 6 GMS by 2020. Decommission of MTSAT-2 planned in 2020. In 2020, MSAS V2 takes over the operation with a new GEO. Integrated to the QZSS program. The L1Sb signal of QZS-3 (GEO) will be used for MSAS service. MCS equipment will also be fully replaced at the same time. 7 GMS will be added: Totally 13 GMS domestic. Performance will be similar with the current MSAS: Horizontal only.

Improvement Plan Supporting vertical guidance: MSAS V2.1 Vertical guidance: LPV operation. Need software upgrade: Adding GMS cannot overcome ionospheric effects. ENRI has been developed the improved algorithms for ionospheric correction. Will be supported in accordance with introduction of the 2nd GEO in 2023. Dual-Frequency operation: MSAS V3 Eliminates ionospheric effects dramatically. Robust vertical guidance (LPV and LPV-200) in the whole Japanese airspace. QZSS GEO will have the L5S signal useable for DFMC SBAS. DFMC: Dual-Frequency Multi-Constellation ENRI will begin DFMC SBAS experiment in 2018 with QZSS satellites. Early opportunity of the DFMC SBAS real signal from the space. Initial test by mid-2017 following launch of QZS-2 IGSO. Expects participation to this experiments from Asia Pacific Economies.

Prototype DFMC SBAS Dual Frequency DFMC L5 SBAS Location: GEONET 950369 (Wakayama) Period: 2016/12/15 (24H) SBAS corrections improve position accuracy in both modes of GPS and GPS+GLONASS. SBAS messages are generated by the prototype DFMC SBAS developed by ENRI, in accordance with the draft DFMC L5 SBAS standards.

MSAS Evolution Plan DFMC SBAS trial begins in 2018; Initial test by mid-2017. Replacement to the new QZSS-based system in 2020. LPV/LPV-200 upgrade likely in 2023 and DFMC SBAS implementation after that.

Conclusion QZSS: Japanese Regional Satellite Navigation System Services: GPS-complement ranging, GNSS augmentation, and Messaging. 4-satellite constellation including 3 IGSO and a GEO in 2018. Will be extended to 7-satellite constellation by 2023. MSAS: Japanese SBAS Service An operational SBAS in accordance with the ICAO standards. Current service: Horizontal navigation (Enroute to NPA performance). Evolution plan: MSAS V2: Replacement to the fully new system and new GEO in 2020. MSAS V2.1: Upgrade for vertical guidance likely in 2023 with the 2nd GEO; Supporting LPV operations. Dual-frequency Multi-Constellation L5 SBAS trial since 2018 with real signals towards MSAS V3; Initial test by mid-2017.
