FAA IRIG B Code Description

SecureSync can be configured to provide IRIG timing, reflecting UTC or local
time, with or without daylight saving time corrections. Below is a detailed descrip-
tion of the FAA modified IRIG B code. The FAA modified the IRIG B code by
including satellite lock status and time error flags in the Control Function Field.
The error flags provide an inaccuracy estimate based on the time elapsed since
loss of GPS lock. In addition, the Straight Binary Seconds (SBS) data was
removed from the data stream. The SBS time is the number of seconds elapsed
since midnight.
