Section #
If available and valid, integrity containment
radius information should be provided to the
54. 8.4.4 ADS-B transmit system from the position data
source, or equivalent, on the same interface as
and together with each positional data.
If the integrity containment radius is not
provided by the horizontal position data source,
the ADS-B transmit system may use other
55. 8.4.5 means to establish an appropriate integrity
containment radius, provided a requirements
compliant integrity alert mechanism is
available.
Use of GNSS Systems as Primary Position Data
56. 8.4.6
Source
GNSS is considered as primary horizontal
position data source for the provision of an
acceptable accuracy and integrity performance
in support of the ATC separation services
contained within the ADS-B-NRA application.
The ED-126 safety and performance
57. 8.4.6.1
assessments are based on the specified
performance and characteristics of GNSS
systems, including receiver autonomous
integrity monitoring. Therefore, for GNSS
systems as specified in section 8.4.6.2, a safety
and performance demonstration is not required.
If GNSS is used as a positional source, the
GNSS system should be either compatible with:
• ETSO C-129A, TSO C-129 or TSO C-129A;
58. 8.4.6.2
or
• ETSO C-145/C-146 or TSO C-145A/C-146A,
capable of delivering position data with a
periodic interval of at least 1.2 s
For GNSS systems compatible with (E)TSO C-
129 (any revision), it is highly desired that the
system incorporates Fault Detection and
59. 8.4.6.3
Exclusion capability as defined in AC 20-138A,
Appendix 1, "GPS as a Primary Means of
Navigation for Oceanic/Remote Operations".
