HYPACK MULTIBEAM COURSE Locations and offsets

OK, so where do I mount my Multibeam System ?? 4/16/2017 HYPACK® 2009 Training Seminar

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. 4/16/2017 HYPACK® 2009 Training Seminar

HYPACK® 2009 Training Seminar Installation Mount your Motion Sensor (MRU or IMU) at the CG or as close as possible. Multibeam Mounting (In 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, in the case of a Gyro-Compass, but a dual antennae DGPS or RTK GPS system will require accurate measurements and placement, in order to output the most accurate data possible. 4/16/2017 HYPACK® 2009 Training Seminar

NOTE: This is usually done with a Land Surveyor’s Total Station. Install your equipment and very accurately Locate each piece with respect to the Boat’s RP/CG. NOTE: This is usually done with a Land Surveyor’s Total Station. “Red Rogers” and drawing (device locations). 4/16/2017 HYPACK® 2009 Training Seminar

HYPACK® 2009 Training Seminar Offsets Adjusting the data for: Boat Origin (Reference Point): Vessel Center of Gravity XY. Static waterline Z. Device Location: Offsets in X, Y and Z measured from boat origin. Device Rotation: Pitch, Roll and Yaw orientation of directional devices such as multibeam sonar. Device Latency: Time delay = data arrival time – data valid time. Tracking Point: XY location of the sonar head. For survey left/right indicator. HYPACK® 2009 Training Seminar 4/16/2017 28 28

Step 1: HYPACK® Hardware Exercise: Project: MB HYPACK Hardware Config There are 6 Basic setups, all of which we will go thru together now. They consist of : Basic DGPS 3) Basic INS w/ DGPS Basic RTK 4) INS – RTK 5) INS w/ Separate RTK 6) Robotic Total Station 4/16/2017 HYPACK® 2009 Training Seminar

Step 1: HYPACK® Hardware Configure HYPACK® Hardware for Position input and HYSWEEP® data transfer. Shared memory transfer… HYSWEEP® Survey HYPACK® Survey Position, Tide, Draft, [Heading] Depth, Heave, Pitch, Roll, [Heading] 4/16/2017 HYPACK® 2009 Training Seminar

Step 1: HYPACK® Hardware Devices: Positioning System: GPS.DLL for position from COM port. Heading and tide if needed. POSMV.DLL for POS/MV positions over a network. Tide if needed. HYSWEEP.DLL for HYSWEEP® depth and motion data from shared memory. Also: Select time synch option on the configuration page. Enter tracking point on the boat page. Added heading 4/16/2017 HYPACK® 2009 Training Seminar

Step 2: HYSWEEP® Hardware Exercise: Project: MB HYPACK Hardware Config There are 5 Basic setups, all of which we will go thru together now. They consist of : HYPACK Navigation and MRU, Gyro, MB Dual Antenna DGPS w/ Heading, MRU, MB INS Serial or Network w/ Motion & Heading, MB INS Network w/ Motion & Heading, 7125 MB INS Network w/ Motion & Heading, Riegl Laser LMS-120Q 4/16/2017 HYPACK® 2009 Training Seminar

Step 2: HYSWEEP® Hardware Configure HYSWEEP® Hardware for Position, heading, tide and dynamic draft from HYPACK® Survey via shared memory. Use HYPACK® Navigation driver. Towfish position from HYPACK® Mobile driver. Only if multibeam is on an ROV or you are towing sidescan. Multibeam, MRU and Heading from other HYSWEEP® network and COM drivers. Hardware program: Use buttons to add / remove device drivers. 4/16/2017 HYPACK® 2009 Training Seminar 34 34

HYPACK® 2009 Training Seminar Navigation Device 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. 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) HYPACK® 2009 Training Seminar 4/16/2017

(Gyro or Dual Antenna GPS) Heading Device (Gyro or Dual Antenna GPS) Offsets: Gyro offsets are not critical but can be entered as measured from boat origin. Connect: Serial Connection HYPACK® 2009 Training Seminar 4/16/2017

HYPACK® 2009 Training Seminar Motion Device Heave, Pitch, and Roll Compensators (MRUs or IMUs) Offsets: Enter MRU/IMU offsets measured from boat origin. Vertical offset is positive downward (i.e. negative above waterline) Connect: Either thru Serial or Ethernet connection HYPACK® 2009 Training Seminar 4/16/2017

Windows Network Setup: Multibeam Device Setup Button: Use the Setup button to enter manufacturer specific information. HYSWEEP® Connect: A Port Number is required for all network devices. Internet Address required for TCP/IP devices. Refer to “Hysweep Interfacing.doc” for details. Your best configuration friend. Windows Network Setup: Network address of the survey computer is set under Windows TCP/IP properties. 4/16/2017
