Fixed Target
Fixed Target Offsets Sub Menu:
Allows the user to enter the fixed target's length, beam, shape and line properties. The reference and heading offsets and the fixed target's latitude and longitude may also be set.
Display Properties:
Vessel Length:
allows the user to enter the fixed target's overall length in feet or meters. The maximum offset that may be entered is 100 meters, the minimum amount that may be enters is 0.1 meters. The default value which will be used if the user has not entered the ships length is 50.0 meters.
Vessel Beam:
allows the user to enter the fixed target's beam in feet or meters. The maximum offset that may be entered is 50.0 meters, the minimum amount that may be enters is 0.1 meter. The default value which will be used if the user has not entered the ships beam is 7.0 meters.
Line Size:
allows the user to select the size (width) of the line used in drawing the fixed target in the viewing area. The allowable line sizes range from 1 to 10 and the default line size is 3.
Line Color:
allows the user to select the color of the line used in drawing the fixed target in the viewing area. The available colors are: black, light gray, dark gray, gray, white, red, yellow, green, cyan, blue, magenta, dark red, dark green, dark yellow, dark blue, dark magenta, dark cyan, money green, sky blue and cream. The default line color is light gray.
Shape:
allows the user to choose a ship shape or barge shape to represent the fixed target on the IPS viewing area. The default shape is ship.
Display:
allows the user to display the fixed target in the IPS viewing area. If display is not checked none of the values selected above will have any effect. The default is display off.
Reference:
Reference X:
allows the user to position the GPS antenna over the hydrophone by setting the reference position to the hydrophones actual position. This frees the user from having to enter hydrophone offsets into the BATS systems.
If the reference X position is starboard of the center of the fixed target the position must be a positive number. If the reference X position is port of the center of the target the position must be a negative number. The maximum offset that may be entered is 1/2 half the amount entered for Vessel's Beam, the minimum amount is the negative of 1/2 the amount entered for Vessel Beam.
Note: To use the reference position a valid compass input must be supplied.
Reference Y:
if the reference Y position is forward of the center of the fixed target the position must be a positive number. If the reference Y position is aft of the center of the fixed target the position must be a negative number. The maximum offset that may be entered is 1/2 half the amount entered for Vessel Length the minimum amount is the negative of 1/2 the amount entered for Vessel Length.
Note: The default reference position is 0,0 the center of the fixed target. The reference position is defined to allow the user the flexibility of selecting a position onboard the target other then the locations of the actual GPS antenna and hydrophone. For example the reference position may be set to the stern of the vessel where launch and recovery of an ROV or other equipment takes place. To use the Reference position valid compass input must be supplied.
Heading:
allows the user to enter the fixed target heading. The maximum heading allowed is 359.0 degrees and the minimum heading is 0.0 degrees. The IPS default heading is 0.0.
Latitude:
allows the user to enter the fixed target latitude.
Longitude:
allows the user to enter the fixed target longitude.
