| 2 || 2 | Introduction One NSP meeting took place since IWG/25: –November 12-21, 2013 Agenda items –Panel organization and work program –Core constellations and SBAS standards and guidance material –GBAS standards and guidance material –Conventional Navigation Aid standards and guidance material –Spectrum issues –Operational implementation issues This briefing reports mainly on SBAS-related discussion –However, some information is provided on a few other topics © 2014 The MITRE Corporation. All rights reserved.
| 3 || 3 | Panel Organization Air Navigation Commission (ANC) is working on a re-organization of panels –Request for consolidation of ICAO technical groups from 12 th Air Navigation Conference (Nov. 2012) –Objectives: improved alignment between panels and work program, and improved coordination among panels –Decision expected to be made soon, but no deadline announced Potential impact on Navigation Systems Panel (NSP) –Spectrum area may be moved to a new Spectrum Panel in which all spectrum related issues would be consolidated –Performance Based Navigation (PBN) work may be moved to NSP renamed simply Navigation Panel Some open issues remained in PBN guidance material when the PBN Study Group disbanded, and these issues are currently slowing PBN implementation in some States © 2014 The MITRE Corporation. All rights reserved.
| 4 || 4 | Work Program (1 of 2) ANC assigned 9 Job Cards to NSP –Job Cards describe new work to be undertaken, including high-level tasks and delivery schedules Job Card concept is being instituted to facilitate ANC review of progress Job Cards were not requested for existing work –So, on-going tasks will continue (without Job Cards) Maintenance of existing standards and guidance material (GNSS and conventional radio navigation aids) Standardization of Galileo and BeiDou core constellations Maintenance of GNSS Manual (Doc. 9849) and Manual on Testing of Radio Navigation Aids (Doc. 8071) –All 5 Job Cards prepared by NSP during March 2013 meeting, plus one prepared by the Secretariat, were assigned to NSP, but the GNSS evolution Job Card was split into 4 separate Job Cards See next page © 2014 The MITRE Corporation. All rights reserved.
| 5 || 5 | Work Program (2 of 2) Job Cards assigned to NSP 1.Maintenance of Navigation Roadmap 2.GNSS Evolution - Multi-constellations 3.GNSS Evolution – SBAS 4.GNSS Evolution – Advanced Receiver Autonomous Integrity Monitoring (ARAIM) 5.GNSS Evolution – GBAS 6.GNSS Radio Frequency Interference 7.Mitigation of Space Weather Effects 8.Rationalization of terrestrial navigation aids 9.Alternative Position Navigation and Timing (APNT) © 2014 The MITRE Corporation. All rights reserved.
| 6 || 6 | Core constellation standards GLONASS –GLONASS status and observed performance –Update to the coordinate system (PZ-90) –Approval of a SARPs change on resistance to interference Corresponding to a similar change in GPS/SBAS SARPs BeiDou –BeiDou status –Initial draft SARPs material for B1I signal (1561 MHz) Further information on use of BeiDou signals requested in order to determine whether B1I needs standards for international aviation Galileo –Galileo status –Initial draft SARPs material for E1 and E5a signals © 2014 The MITRE Corporation. All rights reserved.
| 7 || 7 | SBAS standards (1 of 2) Proposed changes to SBAS SARPs for consistency with SBAS user receiver MOPS, DO229D, Change 1 –Approval of change package containing 24 changes to reconcile requirements in SARPs with those in avionics MOPS Change should be reflected in Amendment 90 applicable in Nov Proposed change to Table on signal-in-space performance –Approval in principle on two proposed new notes to (1) declare APV-II non-applicable to SBAS and (2) clarify that SBAS can be used for LNAV/VNAV operations Exact wording still to be agreed Approval in principle will be used for coordination with Instrument Flight Procedure Panel (IFPP) which had commented on difficulties created by APV-II and lack of LNAV/VNAV lines in Table for their work –IFPP is responsible for developing PANS OPS (Doc. 8168) © 2014 The MITRE Corporation. All rights reserved.
| 8 || 8 | SBAS standards (2 of 2) RTCA SC-159 WG2 report –Decision to start gathering data on dual-frequency, multi- constellation SBAS signal-in-space and concept of operation RTCA/EUROCAE score card –On-going effort to document information needed from core constellation providers to support the development of avionics MOPS, and the information that is available Expect completion for GPS and Galileo by end of 2013 Requested help from Russian and Chinese colleagues for GLONASS and BeiDou to complete the score card IWG progress –Analysis of two options for message structure is expected to converge to a consolidated structure in Spring of 2015 © 2014 The MITRE Corporation. All rights reserved.
| 9 || 9 | Multi-constellation GNSS (1 of 2) Service provision in the multi-constellation context –Observations on provision of air navigation services (as per Chicago Convention) and provision of core constellation services Need for some form of augmentation (e.g., RAIM) to achieve integrity requirements Need for cooperation between core constellation service provider (CCSP) and air navigation service provider (ANSP) of the same State to support safety case and approvals –Requires failure modes and effects data, details of which are often not made publicly available Basis for other ANSPs to approve the use of the services –Requires commitment from CCSP to ICAO to meet certain standards Examples: for GPS Annex 10 refers to standard positioning service performance standard and has major service failure standard –Author suggests that more detailed information on failure modes and probabilities may be needed for approvals in multi-constellation context © 2014 The MITRE Corporation. All rights reserved.
| 10 | Multi-constellation GNSS (2 of 2) Observations regarding the development of multi-constellation systems –Air navigation service providers are responsible for approvals This implies that ANSP assumes responsibility for safety Performs some data recording for potential incident investigations Is satisfied that approved core constellation meets the standards –The latter point can be based on thrust into the processes of ANSP of State of CCSP (e.g., approvals by FAA of navigation based on GPS/RAIM) and/or active data recording and analysis –Panel agreed to develop further guidance on related issues Objectives of data recording and monitoring, methodology, policy for retention of data, reporting and notification in the case of observed anomalies © 2014 The MITRE Corporation. All rights reserved.
| 11 | Advanced RAIM To what extent should ARAIM be standardized? –Additional performance requirements (beyond those already in Annex 10)? –Link(s) to transmit the Integrity Service Message (ISM)? –Elements of the algorithm? Update on progress in related research and development –To be provided at the next meeting (May 2014) Input to standardization work –To be provided at the following meeting (October 2014) © 2014 The MITRE Corporation. All rights reserved.
| 12 | Other Areas of Work (1 of 2) GBAS –Conclusion that standardization of Terminal Area Procedures (TAP) was premature at this time –VHF Data Broadcast (VDB) link budget continues to present difficulties; industry to consider raising height above runway surface to 45 ft for minimum signal level –Validation of GBAS Approach Service Type D (GAST-D) is progressing and finalization of SARPs material is expected in 2 nd quarter of 2015 Spectrum –Panel agreed to develop guidance material on reporting of international interference incidents based on earlier ICAO bulletin and material from a EUROCONTROL workshop © 2014 The MITRE Corporation. All rights reserved.
| 13 | Other Areas of Work (2 of 2) Conventional Navigation Aids –Several papers on rationalization (decommissioning) of VHF Omni- Directional Range (VOR) will be used as input to development of ICAO guidance –Potential way forward on updating the guidance material on Instrument Landing System (ILS) Critical and Sensitive Areas by raising minimum level for localizer signal protection from 200 to 400 feet Further work on glide slope protection still needed Interference from repeater stations –Results of German study on position errors from airborne receiver affected by repeater signals exceeding power limits Suggests further robustness and/or ability to detect and alert be built in future receivers Issue to be brought to attention of RTCA and EUROCAE © 2014 The MITRE Corporation.
