ProMapper Add-On Software
Teledyne BlueView offers ProMapper geo-referencing and sonar mosaicking software. ProMapper
enables the users’ ability to display a portion of the standard 2D data window on to a real world
background image or nautical chart. This capability allows the user to easily combine the ease of use of a
Teledyne BlueView forward looking sonar, with practical mapping displays to greatly increase operational
efficiency. The real time map display allows the sonar operator to quickly assess coverage, sonar data
relative to reference points, and interpret the data in the larger context of location and setting. In addition,
because the data is displayed on screen in its true location with a graphical indication of vessel position, it
is easy to reacquire targets quickly for further investigation.
GPS Heading/Compass Calibration
The BV3200 system GPS is factory calibrated for areas without a unique magnetic signature. Depending
on accuracy requirements, it may be desirable to calibrate the BV3200 to its own unique, as-installed
configuration. Additionally, if the GPS Heading/Compass readings become inaccurate, this calibration
step can be used as an attempt to correct the issue. The GPS unit mounted inside the BV3200 has an
auto calibration feature which can be performed by following the steps outlined below.
IMPORTANT: Calibration requires the vessel to complete 2 to 3 circles. The compass should be
calibrated to achieve maximum sensor accuracy. Use of a timer or stop-watch is recommended as the
steps are time-dependent.
Auto Calibration Procedure
1. Install the BV3200 on the vessel with the arrow on the top of the unit pointing parallel to the boat
centerline, and in the direction of forward travel.
2. In calm seas, navigate the vessel to an open area of water, 0.8 km (0.5 mile) of open space away
from other boats or ferrous objects (structures or aids to navigation).
3. Power-cycle the BV3200 junction box.
4. Open ProViewer 4 and display GPS data.
5. Within 2 minutes of cycling the power, steer in a circle at 4 to 6 kts (5 to 7 mph), taking about 2
minutes to complete a circle. Heading information will disappear, indicating that calibration has
begun.
6. Complete 3 to 4 circles, maintaining speed until the Heading information reappears, indicating
that calibration is complete.
If calibration fails, the display will flash Heading ON and OFF in 10 second intervals for 60 seconds.
(Display times may vary by manufacture.)
IMPORTANT: In the event of a calibration failure, repeat the Auto Calibration procedure.
* The optimum rate of turn is 180°/ minute: 3°/second, 30°/10 seconds, 45°/15 seconds, and 90°/30
seconds.
