TMG1210 GNSS and IRIGB disciplined time & frequency generator The TMG11210 is a GNSS/IRIGB disciplined time & frequency generator designed for a wide range of applications. The equipment is housed in 1U 19" standard case. 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 synchronisation 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. Oscillator An internal OCXO type oscillator provides a 10 MHz frequency used to maintain time. The stability of this oscillator is better than ± 1x10-9 per day in case of loss of external time sourcing. When disciplined by the GNSS, the long term stability remains better than 5x10-". NTP Service The TMG1220 includes a time service implementing standard NTP protocol (Network Time Protocol) allowing any computer or equipment linked to the network to synchronize. Customer's computers can be synchronized with an accuracy of 1 to10ms. NTP client software must be installed on each client for its synchronization with the server. Remote control The remote control of the equipment is done via the network, using an internal web server Configuration The overall configuration of the unit is stored on a removable SDCARD memory which allows remote software update easily.
