1. Introduction
The Tritech MicronNav system is an innovative Ultra Short Base Line (USBL) acoustic
tracking system designed for tracking or marking the position of underwater vehicles or
objects. The design of the system provides 180° hemispherical coverage from the surface
unit and 360° omni-directional coverage from the subsea unit enabling continuous reliable
tracking even in very shallow water. The size of the subsea unit is small enough to be fitted
to the smallest of observation class vehicles.
The system can be used stand-alone in Transponder mode in which case the subsea unit
only requires power, or it can be used with Tritech's range of imaging Sonars (Micron MKII
or MKIII, Super SeaKing and Gemini) in responder mode in which case the subsea unit is
powered by and communicated with through the Sonar Aux port. It is synchronised with the
Sonar to reduce the effect of acoustic interference on the sonar display. For compatibility
with other Tritech International Ltd Sonars see Chapter 8, Using with Other Tritech Sonars
The MicronNav system consists of a Seanet Pro application software package for installation
onto a suitable PC or laptop computer, a small surface MicronNav100 Interface Hub, a
lightweight surface USBL ‘Dunking’ Transducer (with integral magnetic compass and pitch/
roll sensor) and one or more small subsea MicronNav Modem heads.
Note
The Tritech SeaHub Surface Interface Module cannot be used in place of the
MicronNav100 Hub.
The Seanet Pro application software running on a PC or Laptop commands the subsea
MicronNav Modem head to transmit an acoustic ranging signal to the Surface USBL
Dunking Transducer. When operating in stand-alone Transponder mode this command is
sent acoustically via the USBL Dunking Transducer, and when combined with the Tritech
sonar and operating in Responder mode this command is sent electronically via the sonar
communications link.
The MicronNav acoustic ranging signal is detected by the USBL Dunking Transducer and
MicronNav100 Hub Interface module and the received signal information sent to the host
Seanet computer for calculation of range and bearing of the subsea head. USBL Dunking
Transducer pitch/roll and heading data from the integral pitch/roll sensors and magnetic
compass are also captured and sent to Seanet Pro for calculation of corrected position to
world axis.
If GPS positional data is available the range and bearing of the subsea head is synchronised
and the Seanet display updated with ships position and ROV position to true world position.
Provision is made to allow position information to be overlaid onto a user supplied bitmap
chart display of the local area if required.
The position fixing cycle is repeated dependent upon the selected update rate (0.5 – 10s).

3. Installing the System
3.1. Preparation
This section is intended to provide the user with sufficient information to allow for the
consideration and preparation of mounting brackets and wiring arrangements prior to receipt
of the system, final wiring however can only be completed once in receipt of the system as
interconnect leads are supplied with the system.
3.1.1. Using the system with the Micron INS
The Tritech Micron INS has been designed to be fully compatible with the MicronNav System
and can be integrated in a variety of ways.
For full details of how to install a Tritech Micron INS with the MicronNav please refer to
the Micron INS Product Manual (document reference: 0722-SOM-00001) alongside this
document.
3.1.2. Mounting the Subsea Modem Head
The Subsea Modem Head should be mounted at the top of the ROV ensuring the transducer
is proud of the ROV fairing with a clear view from the transducer to the surface, also
remembering to ensure enough room is left to enable the cable connection to be made to the
Micron connectors. To assist with the mounting there are 4 off M3 x 0.5 tapped 5.0 deep full
thread fixing holes in the base of the unit (note: these are protected with plastic grub screws
when shipped from the factory and should be removed prior to using). An alternative method
of mounting the head is to gently grip with a 50mm diameter clamping mechanism around
the bottom part of the housing (in this case the plastic grub screws fitted to the fixing holes
should be left in place).
Caution
It is recommended that any fixing screws used should be of non-metallic material
to reduce the risk of corrosion around the fixing positions.

3.1.3. Mounting the Surface USBL Dunking Transducer
The USBL Dunking Transducer should be mounted from the fixed platform/dockside or
mobile platform/vessel such that the transducer head is at least 1m to 2m below the surface
of the water and at least 1m to 2m away from the dock wall or vessel, if operating from a
vessel it may be difficult to achieve 1m to 2m clearance from the side so in this case lower
the head deeper to ensure a clearance of 1m to 2m below the bottom of the hull.
Caution
The depth of the head must not exceed 10m. Also, when installing on a vessel it
is important to ensure the head is mounted clear of any propellers or thrusters.
The USBL Dunking Transducer contains an integral Magnetic Heading and Pitch/Roll Sensor
that enables the MicronNav Seanet application software running on the surface computer
to make corrections to world axis, this is particularly effective when operating from a non-
magnetic mobile platform/vessel or fixed dockside.
When operating from a steel hull vessel the integral sensor will be affected by magnetic
interference from the vessel and it is recommended in this type of installation that an external
Ships Compass & Motion Reference Unit (MRU) is used to provide the Heading and Pitch/
Roll information, details of how to connect and use an external Compass & MRU sensor can
be found in Section 3.2.7, “Connecting optional third party High Accuracy Heading/Pitch/Roll
MRU Sensors”.

Installing the System MicronNav System
0656-SOM-00001-07 14 © Tritech International Ltd.
The USBL Dunking Transducer is supplied with a short mounting pole (0.5m long) that will
screw into the 22mm diameter coupling on the top of the USBL Head mounting flange and
provide a clamping point for attaching to the users installation. The mounting flange coupling
is a standard 22mm water pipe fitting (UK) enabling a standard 22mm diameter copper water
pipe to be used as a mounting pole fitting directly to the head.
An alternative method of mounting the head is to fabricate a dedicated mounting bracket
and fasten to the USBL mounting flange. It is recommended however that a non-magnetic
material is used for the fixing so as not to affect the integral Magnetic Heading and Pitch/
Roll sensor, if the user wishes to use stainless steel for the fabrication some Duplex Alloys
such as FerraliumSD40 are particularly good but are rather exotic, stainless steel 316 (typical
material used for sub-sea housings) however has little effect on the compass readings and
could be used as an alternative.
Caution
When operating from a vessel consideration should be given to the speed the
vessel is likely to be travelling and the resultant force/pressure the USBL Dunking
Transducer mounting arrangement will need to withstand.
The yellow line indicates the front of
transducer head. This should be positioned
facing in the required forward position to
ensure correct representation on the PPI
display when set to “Ships Head Up”. If
operating from a fixed platform/dockside this
would normally be facing away from the
platform/dockside and if operating from a
mobile platform this would normally align with
the front of the vessel.

3.1.4. Electrical Connections to the Subsea Modem Head
Responder Mode
In Responder mode there is no direct connection from the ROV to the sub-sea Modem head
- in this configuration the ROV connects to the Tritech Sonar head (Main port) using the cable
supplied with the Sonar, and the MicronNav sub-sea Modem head (Main port) connects to
the (Auxiliary port) of the Sonar using the Double Ended Interconnect cable supplied with
the MicronNav system.
Transponder Mode
In Transponder mode the MicronNav subsea Modem head only requires power supply
connections - this can be from the ROV, a stand-alone underwater battery pack or from the
Auxiliary port of any of the Tritech subsea heads.

3.1.5. Electrical Connection to the Surface USBL Dunking Transducer
The USBL Dunking Transducer is supplied complete with underwater cable moulded directly
onto the head and a DB-25 connector at the dry side for connection directly into the USBL
connector on the rear of the MicronNav100 Interface Hub.
3.1.6. Electrical Connection to the Surface MicronNav100 Interface Hub
The surface MicronNav100 Interface Hub requires power from a 90 to 264V AC supply 47
to 63Hz, or a 12 to 36V DC supply - power consumption from either source will be typically
4.8W (with no additional external device load).
Communications from the MicronNav100 Interface Hub to the Subsea head (if being used
with Micron/SeaSprite Sonar) is via a DE-9 socket which connects to Port B plug on the rear
of the unit.

Communications from the MicronNav100 Interface Hub to the computer running the
MicronNav Seanet application software is via a USB Type-A to Type-B cable supplied with
the system, connection is to the rear of the unit.
3.1.7. External Computer Data Link Electrical Connections
If the MicronNav data is required by a third party software package running on an external PC
then connection from the Surface MicronNav100 Interface Hub to the external PC is made
via one of the four serial interface connectors located at the rear of the unit, Port A, B, C or
D. (Note: If the system is being used in Responder mode Port B will be used for the Sonar
communications and will not available for this).
If ports A, B or C are to be used for external communications a DE-9 socket should be wired
as above, if port D socket is to be used a DIN-45322 (6 pin) plug is required and should be

3.2.3. Surface Hardware Installation and Configuration
Caution
The power should be turned off before making a connection between the sonar
head and surface controller (SCU or SeaHub).
Carefully unpack the system from the transit case and uncoil the USBL cable, the
MicronNav100 Hub is located underneath the lift out section containing the Subsea Modem
Head and cable assemblies.
If the supplied mounting pole is to be utilised fit it to the standard plumbing fitting on the brass
mounting plate on top of the USBL Head and connect the USBL Head cable connector to the
DB-25 socket on the rear panel of the MicronNav100 Hub.
Note
It is recommended to wait until after the system has been fully configured and
the Dry System check completed before fitting the USBL Dunking Transducer to
the desired mounting arrangement.
Connect the computer USB port on the rear panel of the MicronNav100 Hub to a USB 2.0
port on the User computer with the supplied USB cable assembly.
Connect power to the MicronNav100 Hub and switch on. The indicator LEDs on the front of
the unit will flash and the ports will auto-install on the computer - this will take a minute or so
to complete and you may be prompted to re-boot the computer.
The Seanet software must now be configured for the MicronNav100 Hub – click the Seanet
Setup icon on the desktop to run the Seanet setup program, select Utilities from the top
menu bar of the Seanet Setup window followed by Com Setup from the sub-menu to open
the Channel Setup page, a dialog box will be opened notifying detection of the SeaHub
