Time and frequency generator TMG1200

GPSdisciplinedGNSS

The TMG1200 is a GNSS/IRIGB disciplined time & frequency generator designed for a wide range of applications. The equipment is housed in a table box. GNSS/IRIGB signal is used for long term disciplining of the internal oscillator. GNSS synchronization 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. IRIGB synchronization The input IRIGB signal is an amplitude modulated analog signal (B12X code) GNSS synchronization is selected first because of its better long term stability. IRIG-B generator 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 reference.
