GPS Locator E934

We regret to inform you that this product is DISCONTINUED; please find our current products here

The purpose of the locator E934 is the position and time determination using the signals of the Global Position System (GPS). The position determination will be used for automatic detection of the buoy drift, the time detrmination is used for the synchronization of flashing of various aids to navigation. It consists of a GPS receiver and a micoprocessor based control unit, designed as a robust compounded device
  • Periodical receiving of the GPS signals with the  user-defined period
  • During every receiving session e the deviations will  be determined: 
             - between the GPS coordinate values and storied nominal values;
             - between the GPS time value and the value of the built-in clock.
  • Computing and recording of the mean value of geographical coordinates.For this the coordinate values of of 256 last receiving sessions will be recorded in the memory 
  • Sending the time messages to the Abus local area network for  adjustment of the built-in clocks of local system units
  • Sending emergency messages to the communication controller,  connected to the Abus when
          - deviation of the geographical coordinates is greater than a pre-set value;
          - deviation of the mean value of geographical coordinates is greater
than a pre-set value;
          - the GPS signal could not be received during the proper time;
          - the voltage on the GPS receiver is below the pre-set limit.

Optionally, the functions of GPS locator can be reprogrammed
to address the specific requirements  of the customer.
