GPS NAi

  • 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 flashcodes in the network of a structure marking system, based on a very precise GPS/GLONASS time base 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 flashcode 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.
