22 10/11/2014HYPACK® Multibeam Training Seminar22 OK, so where do I mount my Multibeam System ??

23 10/11/2014HYPACK® Multibeam Training Seminar23 Boat Reference Point (RP) 1) Locate your Boat’s Center of Gravity (CG). 2)This will be critical to performing very accurate and repeatable surveys. 3)Understand that your boat’s CG may be dynamic and need to be monitored.

24 10/11/2014HYPACK® Multibeam Training Seminar24 1)Mount your Motion Sensor (MRU or IMU) at the CG or as close as possible. 2)Multibeam Mounting (Main Concern - MOUNT AS RIGID AS POSSIBLE) (Order of preference) (Order of preference) Hull Mount at boat’s CG. Hull Mount at boat’s CG. Moon Pool at boat’s CG Moon Pool at boat’s CG Pole Mount; Thru Hull, Over-the-Bow Pole Mount; Thru Hull, Over-the-Bow Mount or Over-the-Side Mount. Mount or Over-the-Side Mount. 3)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) 4)Heading Device Location not as critical, however, accurate Offset measurements and placement, will aid in the most accurate data possible. Installation

31 10/11/ Offsets Adjusting the data for: Boat Reference Point:Boat Reference Point: Vessel Center of Gravity = XY (0,0) (Boat Origin) Static waterline = Z (0) Device Location:Device Location: Offsets in X (Stbd), Y (Fwd), and Z (Vertical) measured from Boat Reference Point. Device RotationDevice Rotation: Pitch, Roll and Yaw orientation of directional devices (MRU & Gyro) with respect to the multibeam sonar. Device Latency:Device Latency: Time delay = data arrival time – data valid time. (Lack of Synchronization between Positioning Device and Sonar Device.) Tracking Point: Tracking Point: XY location of the sonar head. For Survey Program’s Left/Right Indicator. Important !! Important !! Crucial for collecting good overlapping Patch Test Data HYPACK® Multibeam Training Seminar 10/11/201431

32 10/11/2014HYPACK® 2009 Training Seminar32 MRU is at boat origin, Tracking Point is over the transducer. MRU Multibeam TRANSDUCER +X +X +Y +Z Boat Reference System Tracking Point Boat Origin & Tracking Point 10/11/ HYPACK® Multibeam Training Seminar

33 33 MRU Multibeam TRANSDUCER +X +X +Y +Z MRU is on Side Mount Pole with the Multibeam Transducer, and the RTK GPS Antenna is over both the MRU and the Multibeam Transducer. Then, Boat Reference Point can be at the Side Mount Pole location. Boat Reference Point Exception to the Rule RTK GPS 10/11/2014HYPACK® Multibeam Training Seminar 33

40 10/11/2014HYPACK® Multibeam Training Seminar40 Step 1: HYPACK® Hardware Devices: Select Positioning System: GPS.DLL GPS.DLL for position from COM port. Heading and tide if needed. POSMV.DLLF180.DLL POSMV.DLL or F180.DLL for positions over a network. Tide if needed. Geodimeter.DLL Geodimeter.DLL for the use with a Robotic Total Station. HYSWEEP.DLL 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.

41 10/11/2014HYPACK® Multibeam Training Seminar41 Step 2: HYSWEEP® Hardware Exercise: Hardware Exercise: Project: MB HYPACK Hardware Config There are 5 Basic setups, They consist of : HYPACK Navigation and 1)MRU, Gyro, MB 2)Dual Antenna DGPS w/ Heading, MRU, MB 3)INS Serial or Network w/ Motion & Heading, MB 4)INS Network w/ Motion & Heading, 7125 MB 5)INS Network w/ Motion & Heading, Riegl Laser LMS-120Q

42 10/11/ HYPACK® 2009 Training Seminar Step 2: HYSWEEP® Hardware Configure HYSWEEP® Hardware for: MUST Use HYPACK Navigation driver. This will bring Position, Tide, and Dynamic Draft from HYPACK® Survey via shared memory. (Heading, if limited ComPorts are available) Add HYPACK Mobile driver, if multibeam is on an ROV, or towing Sidescan or collecting a redundant Positioning System. Multibeam, MRU and Heading from other HYSWEEP® network and COM drivers. Hardware program: Use buttons to Add / Remove device drivers. 10/11/201442HYPACK® Multibeam Training Seminar

43 10/11/2014HYPACK® Multibeam Training Seminar43 Navigation Device Offsets: Enter GPS antenna offsets measured from Boat Origin. Vertical offset is positive downward (i.e. negative above waterline). Enter GPS latency if any. (Offsets DO NOT carry thru Shared Memory) The HYPACK Navigation device is required and is installed by default. Not good if you delete it. Connect: Shared Memory transfer is automatic and requires no configuration.
