GPS NAi
GPS Unit
- Exact day-night switching and GPS-precise synchronisation of all flashcode generators according to IALA standard in the NAi network
- GPS/GLONASS based UTC time base
- Integrated ambient light measurement with programmable switching threshold
- NAi bus interface for power supply and communication
- More than 2 hours of holdover performance for the synchronisation
The SABIK GPS NAi is a GPS device that provides day-night information and synchronisation pulses for the flash codes in the network of a structure marking system, based on a very precise GPS/GLONASS time stamp and an integrated ambient light sensor.
The day-night switching occurs depending on
- The ambient brightness and
- The current date in conjunction with the Cuxhaven calendar (North Sea or Baltic Sea) or
- The geographic position of the device according to the astronomical clock.
The exact flash code synchronisation of the connected navigation light components is guaranteed even in the event of a weak or absent GPS/GLONASS signal over a time period of at least 2 hours.
