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
Features
-
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.
