IMS Clock Module with Multi GNSS Receiver for GPS, Galileo, GLONASS and Beidou

Central clock module for the Meinberg IMS platform. The Multi GNSS receiver can use an external antenna to receive GPS, Galileo, GLONASS and Beidou satellite signals, decode them and use them as a reference source for the integrated, oscillator-based hardware clock. In addition to synchronizing with the GNSS systems, the IMS-GNS clock module accepts a wide range on input references when combined with IMS input cards.

Further information The IMS-GNS module can be installed in any Clock (CLK) 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 a network interface to Synchronise to an external NTP server or PTP/SyncE source. The Meinberg MRS concept supports setting up a prioritized list of input sources that are used to Synchronise the internal hardware clock of the IMS-GNS and then generate a large number of different output signals used by IMS I/O compatible cards to provide a user-defined selection of Synchronisation output signals by adding BPE, CPE or other IMS modules.

By combining the IMS-GNS module with another Clock module and an RSC switch card, a fully redundant Synchronisation solution can be created.

The integrated GNSS receiver requires an external antenna. It can be configured to use GPS, Galileo, Beidou and GLONASS. The configuration supports to select one of these to be used exclusively or a combination of up to three of the sources. The receiver is capable of operating during high speed movement and delivers reliable and highly precise Synchronisation 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 one or more IO output cards like the BPE or CPE modules. Various output modules offer all kinds of different electrical or optical interfaces and signal types.

The IMS-GNS module is hot-swappable and is automatically detected by the management CPU of an IMS system.
RoHS Yes
