making significant safety-related changes to
ATC system
Systematic analysis of hazards and
mitigations during all phases of system’s life
cycle
GNSS safety plan
ATMB–CAAC Workshop on GNSS Beijing, 16-17 April 2007
Certification and operational approvals
State responsibility to authorize GNSS operations
in its airspace
Approval document: for aircraft with certified
equipment and approved flight manual
Specifies any limitations on proposed operations
VFR use or IFR use
GNSS alone or with other systems
Airworthiness certification based on
RTCA/EUROCAE documents
ATMB–CAAC Workshop on GNSS Beijing, 16-17 April 2007
Anomaly reporting
Anomaly: GNSS service interference)
Pilot to report to ATC asap requesting special
handling as required and file complete report in
accordance with State procedures
Controllers to record information of the occurrence,
to identify other GNSS-equipped aircraft that may
be affected, and to forward information to
designated authority
National focal point unit to information
outage (may be due to
collect anomaly-related
ATMB–CAAC Workshop on GNSS Beijing, 16-17 April 2007
Vulnerability
Potential for interference is the main vulnerability
Receiver interference mask specifies the level of interference that can be
tolerated
Several interference sources (eg microwave links within L1 band in some
States)
Unintentional vs intentional interference
States should:
assess sources of vulnerability and develop mitigations (technical,
procedural back-up)
provide effective spectrum management and protection of GNSS
frequencies to reduce the possibility of unintentional interference
use on-board mitigation techniques (eg inertial)
consider selective retention of conventional navaids as part of an
evolutionary transition
take full advantage of new GNSS signals and constellations
ATMB–CAAC Workshop on GNSS Beijing, 16-17 April 2007
GNSS and PBN
ALL PBN Navigation specifications are
based on GNSS either as the primary
navigation infrastructure or as one
element of the infrastructure

Aviation challenges
:
Growing demands for RNAV approaches (safety,
accessibility)
Growing demands for solution airspace congestion
Growing fuel efficiency requirements
Growing Environmental requirements
Can be met with most of current technology,
but standardization and operational
place
requirements have to be put into

Background
ICAO RNP concept
FANS identified need for performance based navigation and
developed Required Navigation Performance capability concept :
To avoid need for ICAO selection between competing systems
Manual on Required Navigation Performance (doc 9613)
Emphasize on the en-route phase of flight (RNP-10 and RNP-4) for
oceanic and remote applications
No ICAO RNP requirements for continental enroute and terminal
applications.
Proliferation of national standards
Wide variety of functional requirements
Variety of required navigation sensors
Differing air crew requirements
Lack of global harmonization
