Overall operation related changes
Navigation sensors
· If position alignment is used then user is reminded of it every 30 minutes. Alarm "2011 ChartAlign: over 30
min".
· In multiple sensor case the Kalman filter indicates changes in its position sources with a new alarm "2010
Filter: Pos source change".
· Kalman filter uses always higher priority for known high precision position sensors than for normal position
sensors (i.e. A DGPS has always higher influence to estimate than a GPS or LORAN)
· Alarm "4027 DGPS pos source change" uses now always a continuous beep until acknowledged. Before the
beep style was dependent of the steering mode. Also the priority of this alarm is readjusted (before some less
important alarm could suppress it in the priority list).
· Alarm "2008 Filter. Speed below 4kt" is now based on ground speed (before water speed). The Kalman filter
indicates this situation also with an permanent indication of BAD FILTER.
· Reference target based gyro error correction has now an alarm for lost correction value. Alarm "2353 RefTgt:
Lost gyro corr.".
· Activation of Reference target requires that there is at least 8 free tracking channels available. If the connected
ARPA radar has less than 8 free tracking channels then there is an alarm "2353 RefTgt: Tracking full".
Route Monitoring
· Selection of "Center and border lines for ARPA radar display" .in route monitoring window is dependent of
used radar display type.
· Alarm "2457 Route: Outside channel limit" is activated once when the ship goes out of the channel limits.
Before the alarm was reactivated every 5 minute. NOTE the permanent indication of "OUTSIDE CHANNEL"
operates as before and give always an indication of route tracking status.
Past Tracks
Own ship has now three separate past tracks:
· "System", which is the past track of the system position used for navigation and steering.
· "Primary", which is the past track of a position sensor selected as Primary.
· "Secondary", which is the past track of position sensors selected as Secondary.
Speed Vectors
· There is now a selection between true and relative speed vectors for own ship and ARPA targets. Before only
true vectors were available.
