8.4.4
If available and valid, integrity
containment radius information
should be provided to the ADS-B
transmit system from the position
data source, or
equivalent, on the
same interface as and together with
each positional data.
The transponder only receives
position related parameters from a
Garmin GNS/GTN Equipment posi-
tion source or other compliant posi-
tion source.
55.
8.4.5
If the integrity containment radius is
not provided by the horizontal position
data source, the ADS-B transmit sys-
tem may use other 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 Source
[Section heading, no

57.
8.4.6.1
GNSS is considered as primary hori-
zontal position data source for the pro-
vision 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 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 demonstra-
tion is not required.
[General information, no
compliance statement req’d]
58.
8.4.6.2
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; 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
