CS-ACNS Compliance Matrix
CS ACNS.D.ADSB.115 Horizontal Position and
Velocity Total Latency
Measured from the time of applicability within the
source, the total latency of the horizontal position
and horizontal velocity data introduced by the
ADS-B Out system does not exceed 1.5 second.
For a GPS source with a 5 Hz update rate:
Position solution update delay until the next solution
overwrite is relayed to the transponder <= 200 ms (5
Hz update rate).
The GTX 3X5 introduces an additional total latency of
<= 400 ms to the ADS-B Out system. Therefore, the
worst case total latency of the ADS-B Out system
with a 5 Hz rate source and the listed assumptions is
<= 850 ms.
For a GPS source with a 1 Hz update rate (ARINC
743) and total latency contribution <= 200 ms:
Position solution update delay until the next solution
overwrite is relayed to the transponder <= 1000 ms
(1 Hz update rate).
The GTX 3X5 introduces an additional total latency of
<= 250 ms to the ADS-B Out system. Therefore, the
total latency of the ADS-B Out system with a 1 Hz
rate GPS source and the listed assumptions is <=
1450 ms.
CS ACNS.D.ADSB.120 Horizontal Position
Uncompensated Latency
The uncompensated latency of the horizontal
position data introduced by the ADS-B Out System
does not exceed 0.6 second.
Uncompensated latency introduced by an approved
GPS source is assumed to be <= 250 ms. See Note 1
for GPS source documentation.
The GTX 3X5 introduces an additional
uncompensated latency of <= 150 ms to the ADS-B
Out system.
Therefore, the worst case uncompensated latency of
the ADS-B Out system with an approved GPS source
and given the listed assumptions is <= 400 ms.
