23. Boat Reference Point (RP)
Locate your Boat’s Center of Gravity (CG).
This will be critical to performing very accurate and repeatable surveys.
Understand that your boat’s CG may be dynamic and need to be monitored.

HYPACK® Multibeam Training Seminar

24. HYPACK® Multibeam Training Seminar
Installation
Mount your Motion Sensor (MRU or IMU) at the CG or as close as possible.
Multibeam Mounting (Main Concern - MOUNT AS RIGID AS POSSIBLE)
(Order of preference)
Hull Mount at boat’s CG.
Moon Pool at boat’s CG
Pole Mount; Thru Hull, Over-the-Bow
Mount or Over-the-Side Mount.
Positioning System Place your GPS antennae as high as possible and directly above the Boat’s CG or as close as possible. Alternate Positioning Systems will require the most visible “line of sight” as possible also (ie. Robotic Total Station)
Heading Device Location not as critical, however, accurate Offset measurements and placement, will aid in the most accurate data possible.

31. Offsets Adjusting the data for:
Boat Reference Point: Vessel Center of Gravity = XY (0,0) (Boat Origin) Static waterline = Z (0)
Device Location: Offsets in X (Stbd), Y (Fwd), and Z (Vertical) measured from Boat Reference Point.
Device Rotation: Pitch, Roll and Yaw orientation of directional devices (MRU & Gyro) with respect to the multibeam sonar.
Device Latency: Time delay = data arrival time – data valid time (Lack of Synchronization between Positioning Device and Sonar Device.)
Tracking Point: XY location of the sonar head For Survey Program’s Left/Right Indicator.
Important !! Crucial for collecting good overlapping Patch Test Data

40. Step 1: HYPACK® Hardware
Devices:
Select Positioning System:
GPS.DLL for position from COM port. Heading and tide if needed.
POSMV.DLL or F180.DLL for positions over a network. Tide if needed.
Geodimeter.DLL for the use with a Robotic Total Station.
HYSWEEP.DLL for HYSWEEP® Nadir depth, Swath painting of Matrix in Map Window, and Heading and Motion data from Shared Memory.
Click on Hypack Configuration, then under the Synchronize the Computer Clock :
(Select the Device that is bringing in the ZDA and/or 1PPS data.)
Click on Boat, then under the Coordinates of Tracking Point window, Enter the Multibeam Head Offsets.
