IMS-GLN Clock: Clock Module with combined GPS/GLONASS Satellite Receiver
Product Description
The IMS-GLN module can be installed in any Clock slot of your IMS system. It is capable of using all the various IMS reference sources, either by adding an MRI or ESI compatible input card or by using the network connection of the CPU to synchronize to an external NTP server. The Meinberg MRS concept supports setting up a prioritized list of input sources that are used to synchronize the internal hardware clock of the IMS-GLN and then generate a large number of different output signals used by IMS I/O compatible cards to provide a user-defined selection of synchronization output signals by adding BPE, CPE or other IMS modules.
By combining the IMS-GLN module with another Clock module and an RSC switch card, a fully redundant synchronization solution can be created.
The integrated GNSS receiver requires an external antenna. It can be configured to only use GPS, only use GLONASS or use both signals in parallel. The receiver is capable of operating during high speed movement and delivers reliable and highly precise synchronization solutions in stationary installations and on fast moving vehicles, such as aircraft, ships or trucks. The signals generated by the CLK module can be used by adding BPE output cards which take the module's signals and make them accessible for the user on a front end. The various front end options offer all kinds of different electrical or optical interfaces. A CPE module will take the signals provided by the CLK module and convert them into other electrical or optical synchronization signals.
The IMS-GLN module is hot-swappabel and is automatically detected by the management CPU of an IMS system.
