The TMG1200 is a GNSS/IRIGB
disciplined time & frequency generator
designed for a wide range of
The equipment is housed in a table box.
GNSS/IRIGB signal is used for long term
disciplining of the internal oscillator.
The internal GNSS receiver is a specific
receiver dedicated to time
application. It's a bi-constellation
model able to acquireboth GPS and
GLONASS satellites simultaneously. It
delivers a very high precision UTC
second reference pulse.
The input IRIGB signal is an amplitude
modulated analog signal (B12X code)
GNSS synchronization is selected first
because of its better long term stability.
The equipment includes an IRIG time
code generator that allows providing
an IRIGB122 signal (amplitude
modulated analog signal) and an
IRIGB002 (DCLS) over RS422.
Those signals are in phase with the
internal 1PPS equipment itself
synchronized on the 1PPS of GNSS
