IRIG-B
IRIG-B is the most common version of IRIG (Inter Range Instrumentation Group).
Why IRIG-B
The need for IRIG standards such as IRIG-B is that standardization of time codes allows equipment to be synchronized to a known reference time. This also allows facilities at geographically separated locations to synchronize to a known time code source. In practice, many labs are equipped with devices that create IRIG time code from GPS Satellite time and distribute time code to other devices for synchronization.

What is IRIG-B
The IRIG-B standard consists of a family of rate scaled serial time codes with formats containing up to three coded expressions or words. The IRIG-B pulse code contains one "frame" of 100 "elements" per second for the time of the year and GPS receiver status. IRIG-B encodes day of year, hour, minute, and second data on a 1 kHz carrier frequency, with an update rate of once per second.

IRIG-B uses
Modern day electronic systems such as communication systems, data handling systems, missile and spacecraft tracking, and telemetry systems require time-of-day information for data correlation with time.
