INTRODUCTION

GENERAL

The global navigation satellite system (GNSS) is defined in Annex 10 - Aeronautical Telecommunications as a worldwide position and time determination system that includes one or more satellite constellations, aircraft receivers and system integrity monitoring, augmented as necessary to support the required navigation performance (RNP) for the intended operation.

The fifth edition of the Global Air Navigation Plan (Doc 9750, GANP) recognizes GNSS as a key element of the air navigation system that will deliver improved services and meet environmental, efficiency and safety objectives.

Assembly Resolution A32-19 - Charter on the Rights and Obligations of States Relating to GNSS Services addresses institutional issues. The Charter highlights the principles that shall apply in the implementation and operation of GNSS, including: the primacy of safety; non-discriminatory access to GNSS services; State sovereignty; the obligation of provider States to ensure reliability of services; and cooperation and mutual assistance in global planning.

States are ultimately responsible for ensuring that new air navigation services meet established safety Standards. In some cases, States pool resources to establish a regional safety oversight organization (RSOO) to ensure a common approach to safety regulation, oversight and enforcement. References to States in this manual also apply to RSOOs.

The content of this manual is aligned with several Assembly Resolutions as well as with the Performancebased Navigation (PBN) Manual (Doc 9613), Safety Oversight Manual (Doc 9734) and Safety Management Manual (SMM) (Doc 9859). Readers should be familiar with these and other relevant ICAO documents.

The navigation and PBN roadmaps in the GANP are reproduced in Appendices D and E of this manual. These roadmaps, which are updated with each GANP revision, outline the time frames for the availability of GNSS elements, the implementation of related services and the rationalization of conventional infrastructure. These roadmaps provide States with planning outlines that are consistent with the ASBUs.

This manual provides information about GNSS technology and operations that will assist States to oversee the safety of GNSS operations and complete the business case analyses needed to support implementation decisions and planning.
