French manufacturer launches GPS module

Increasing the efficiency of marine traffic lights, the ZTI 1250 synchronization module can generate temporal signals synchronized to UTC time thanks to the embedded GPS receiver.

Two outputs are available, and each output can be set to one of the four available functions, which are TOP synchronisation with frequency adjustment, time scheduler, twilight switch, and out of position notification for displaced buoys.

The TOP synchronizationfunction is well suited for multiple maritime signaling equipment with the same lightning frequency, such as alignment lighthouses, fairway buoys or port entry doors (port and starboard lights). The ZTI 1250 module can thus synchronize time of light and darkness of these maritime lights, ensuring better readability and increased safety. The user can set different adjustment parameters such as pulse duration, periodicity and timing offset.

The time schedulerfunction enables daily scheduling for a logical output based on user defined time slots. To reflect the night length variation over the days better, the module automatically computes sunrise and sunset switches, depending on settings for the days of solstices (winter and summer) and equinoxes.

For the twilight switchfunction, the ZTI 1250 module automatically calculates aurora and daybreak hours from the location determined by GPS. The logical output assigned to this function is therefore activated daily according to the calculated hours for sunrise and sunset (a positive or negative user defined offset can be added).

The out of positionfunction is mostly used for maritime signaling floating equipment such as buoys. The objective is to alert the user or to perform an action when the buoy leaves its correct position area.
