The Mega-Guard Hydro Acoustic Position
Reference (HPR) is applied as a cost effective
and highly accurate position reference system
for a Dynamic Positioning System DP1, DP2
and DP3. The position of the seabed USBL
Transponders are used as reference points
for the ship mounted USBL Transceiver.
The USBL Transceiver is connected to the
HPR Workstation through Ethernet connection.
The MRU-INS, gyro and optional DGPS are
connected as well to the HPR Workstation.
The HPR Workstation accurately calculates
the relative position of the vessel taking into
account the data as received from the USBL
Transceiver, MRU-INS, gyro and optional
DGPS. The USBL Transponder contains a
release mechanism with floating collar for
recovery of the transponder from the seabed.
The Mega-Guard Hydro Acoustic Position
Reference consists of the following
components:
HPR Workstation providing a user friendly
man-machine interface
USBL Transceiver with a 5000 meter range
USBL Transponders for 4000 meter
water depths.
Motion Reference Unit
Control Cabinet
The USBL Transceiver can be mounted in two
different ways:
Hull mounted with gate valve and
deployment machine
Pole mounted with over-the-side pole
Accuracy Hydro Acoustic

Floating Collar
Accuracy specified at 1500 meter range and
water depth (0 degrees beam angle) and no
influence from roll / pitch / yaw of ship and no
influence from sound velocity variation.
HPR Workstation
Mega-Guard Workstation: Marine PC,
19~22” TFT and Trackball.
Ethernet link to USBL Transceiver.
NMEA inputs: Gyro, Motion Reference
Unit with optional INS and DGPS.
NMEA output: position data connected to
DP system through Ethernet or serial link.
Dead reckoning with position improvement
through MRU-INS (option)
