Blocking map for optimization of blocking zones
The blocking map is intended as a tool to optimise the blocking zones in order to
reduce the antenna’s downtime. It shows the active blocking zones and an automatic
evaluation of the antenna reception. Over time the antenna can determine where the
signal is blocked by structures on the ship. The blocking map helps you to set more
accurate blocking zones.
To enable a blocking zone and display it on the blocking map you must select Active.
The re-defined zones will show immediately on the map. The blocking map is updated
every 12 hours, showing whether the antenna has been in a blocking zone or has
received a signal. After a voyage of days, weeks, months the blocking map will display
where the blocking zones are. The time it takes to draw a meaningful map depends on
the ship’s size and motions throughout the voyage. A small ship following a school of
fish will have a populated map faster than a larger tanker sailing across the Atlantic
ocean. The following figure shows an example.
You can clear the map at any time.
