GPS Locator E931


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

The purpose of the locator E931 is the position and time determination using the signals of the Global Positioning System (GPS). The position determination will be used for the automatic detection of buoy drift , the time determination is used for the synchronization of flashing of various aids to navigation. It consists of a GPS receiver and a microprocessor based control unit, designed as a Eurocard form factor device. In order to achieve long life span it should be installed into a hermetic enclosure.
 
Features
  • Periodical reception of the GPS signals with the user-defined  period
  • During every receiving session  the deviations will be determined:
          - between the GPS coordinate values and recorded nominal values;
          - between the GPS time value and t thealue of the built-in clock. 
  • Computing and recording of the mean value of geographical coordinates. For this the coordinate values of 256 last receiving sessions will be recorded in the memory 
  • Sending of the time messages to the Abus local area network for the 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
