CF = Control Field
SBS = Straight Binary Seconds
Note: The available options will vary according to the values of Format and Mod-
ulation Type.
Control Function Field: IRIG signals have an optional section in the data stream that can
be used to include additional information (such as the present year, for example). This
field allows the Control Field section of the IRIG output to be defined. The available con-
figurations are:
Fields conform to RCC 200-04: IRIG spec 200-04 specified a location for year
value, if included in this field.
Fields conform to IEEC 37.118-2005 (IEEE 1344): Control Field contains year,
leap second and daylight savings time information.
Fields conform to Spectracom Format: Year is included in Control Field but not in
the same location as RCC-2004 output (year is offset by one position).
Fields conform to Spectracom FAA Format: A unique IRIG output Control Field that
contains satellite lock status and time error flags.
Fields conform to NASA Formats: Variants of IRIG B
Fields confirm to Spectracom IEEE C37.118-2005: Has been extended to support
one-month leap second notification
Note: The available options will vary according to the configurations of Format
and Modulation Type.
Timescale: Used to select the time base for the incoming time code data. The entered
Timescale is used by the system to convert the time in the incoming data stream to UTC
time for use by the System Time. The available choices are:
UTC: Coordinated Universal Time ("temps universel coordonné"), also referred to
as ZULU time
TAI: Temps Atomique International
GPS: The raw GPS time as transmitted by the GNSS satellites (as of July, 2015,
this is 17 seconds ahead of UTC)
