ICAO 9849 PDF

FOREWORD

The sixth edition of the Global Air Navigation Plan (GANP, Doc 9750) presents a high-level summary of ICAO’s aviation system block upgrade (ASBU) methodology. The ASBU framework drives the evolution of the global air navigation system towards the achievement of the performance ambitions outlined in the GANP by defining operational improvements and associated performance benefits. The Global Navigation Satellite System (GNSS) is recognized within the ASBU methodology as a key element of the air navigation system that will deliver improved services and meet these objectives.

The Standards and Recommended Practices (SARPs) for GNSS were introduced in 2001 as part of Amendment 76 to Annex 10 to the Convention on International Civil Aviation – Aeronautical Telecommunications, Volume I – Radio Navigation Aids. The guidance information and material in Attachment D to Annex 10, Volume I provide extensive guidance on the technical aspects and the application of GNSS SARPs. The Navigation Systems Panel (NSP) continues to develop new material for publication in Annex 10 amendments.

The primary purpose of this manual is to provide information on the operational implementation of GNSS to assist States to introduce GNSS-based services. The manual is therefore aimed at air navigation service providers responsible for fielding and operating GNSS elements, and at regulatory agencies responsible for approving the use of GNSS for flight operations. Additionally, it provides GNSS information to aircraft operators and manufacturers.

This manual is to be used in conjunction with the relevant provisions in Annex 10, Volume I, and with the Performance-based Navigation (PBN) Manual (Doc 9613) as well as the Manual of All-Weather Operations (AWO, Doc 9365).

Comments on this manual would be appreciated from all parties involved in the development and implementation of GNSS-based services.
