39. IRIG- B INTRODUCTION
IRIG-B standard time format by telecommunication working group . Inter range
instrumentation group range commanders council describes IRIG-B it is available by
writing secretly range commanders council. White sand missile range new Mexico
880022.
The standard time format of IRIG-B Code were designed for us in missile , satellite and
space research programmers. Use of these code facilities efficient interchange of test
data Those formats are suitable for recording on magnetic tape oscillo graphics film
and for real time transmission in both automatic manual data reduction . IRIG-B from
the SERTEL
GPS / MASTER CLOCK system is suitable for remote display driving magnetic tape
recording and may other use. IRIG-B codes in the strip sense encode Universal Co-
ordinate Time (UTC) in 24 Hours format only not local time. Nonetheless this
instrument can encode UTC and IST time in 24 hours format.
The frame length of IRIG-B is 1 second long and contains 100 elements (pulse) each of
which starts every 10 milli second (unmodulated) and 1 Milli second (modulated) .
SERTEL GPS/MASTER CLOCK provide output of IRIG-B in amplitude modulated
signal(1Khz) output at rear panel of BNC Connectors. This will help us long distance
communication.
