CDL Products (Inertial)

• MiniPOS/NAV
• CDLs flagship inertial product is a single
  housing packaging of CDL MiniPOS2 and the RDI
  Workhorse Navigator DVL system. This powerful
  combination produces a complete inertial
  navigation system capable of tracking absolute
  position at up to 0.1 of distance travelled.
  The MiniPOS/NAV allows known object positioning
  on the seafloor with no requirement for external
  acoustic beacons.
• MiniPOS2
• MiniPOS2 is a Ring Laser based navigation system
  that can calculate position and output data in
  x,y,z or lat,long and height. MiniPOS2 can also
  accept aiding from external devices to allow it
  to navigate more accurately. Current aiding
  devices are GPS (surface) or Doppler Velocity
  log (subsea). A lower cost product known as
  MiniRLG2 is based on the same technology for
  heading, pitch roll output.
• RemoteGyro
• The CDL RemoteGyro is a battery powered RLG
  system for use in template installations on the
  seabed where it is undesirable to have direct
  connection to the surface. The data from a
  MiniRLG2 can be read on a MiniTXT subsea display
  or transmitted via DATUM acoustic modem.
• TOGS
• The CDL TOGS (Tiny Optical Gyro System) is a low
  cost FOG (Fibre Optic Gyro) based North seeking
  compass for use on vessels and Remotely Operated
  Vehicles (ROVs). TOGS provides fast North
  seeking, high accuracy and light weight at a
  price comparable to most spinning mass gyros.

CDL Products (Attitude)

• MicroTilt
• This is a simple dual axis accelerometer which
  can be used for low cost attitude applications
  when high update rates are required. Note that
  this is a 2 axis system only so it has no way of
  telling the difference between a pitch angle and
  a sideways movement.
• MiniSense
• MiniSense is a MEMS based 6 DOF sensor which
  computes attitude as well as heave. This is a
  much lower cost heave sensor than most other
  systems which are based on pendulum
  accelerometers.
• MiniTilt
• The CDL MiniTilt is a long standing successful
  product with several hundred systems out in the
  field. It is a high accuracy, but low dynamic
  pitch and roll sensor which reads to 0.05 degrees
  in both axes at an update rate of 4 Hz. It gives
  these angles over the full range of 360 degrees.

CDL Products (Telemetry)

• DMV / MiniVision / MicroVision
• The MicroVision range of products from CDL offer
  a variety of methods and frequencies for the
  transmission of high quality video signals via RF
  telemetry. The top of the range DMV (Digital
  MicroVision) offers better than DVD quality
  signals with zero BER (Bit Error Rate) at
  distances of up to 20km.
• MiniWire
• MiniWire is a long range serial data telemetry
  system allowing transmission at speeds up to
  16,000bps. It uses Forward Error Correction
  (FEC) for high data integrity and has multiple
  channel capability to allow simultaneous
  transmission of several data streams
  simultaneously.
• MiniPlexer
• The CDL MiniPLexer system is a data multiplexer
  for use on ROV systems that sends up to 8
  channels of bidirectional data over a twisted
  pair copper connection at speeds of up to 115Kbps

CDL Products (Acoustics)

• DATUM
• The CDL DATUM is a high speed subsea modem with
  ranging capability. It is small in size, low
  cost and can be used for a wide range of acoustic
  tasks including an innovative networking feature
  where data can be passed along a subsea array of
  DATUM units allowing information from any point
  in the array to be accessed from any DATUM
  within range of the ROV or vessel.
• CMT
• The CMT (CDL Metrology Tool) is a combination of
  CDL sensors in a single package to allow remote
  attitude monitoring of subsea structures as well
  as a large variety of other integrated sensor
  tasks.
• A CDL TOGS North seeking FOG system is packaged
  with a battery pack and DATUM acoustic ranging
  modem. This package sits on top of a keyed
  docking receptacle system which allows easy
  installation and recover by diver or ROV. A
  locking pin arrangement can be used to hold the
  CMT in place to allow safe pre-installation of
  the system prior to deployment of subsea
  structures.
• Battery life is over 28 hours and the unit has
  the capability to remotely shut down and
  re-enable the gyro to extend battery life to
  several weeks.
• Once enabled the system can provide heading,
  pitch and roll information from the TOGS as well
  as information from other external sensors. The
  ranging function allows the CMT to be used in
  positioning applications.

CDL Products (Display)

• DDU2
• The DDU2 unit is a compact and powerful
  touch-screen solid state embedded PC designed for
  use in harsh environments. It provides display
  and control functions for the full range of CDL
  products as well as the capability to run client
  provided software. The DDU2 is controlled via an
  8.4" 800x600 touch screen display giving a large
  viewing area and high resolution.  The DDU2 can
  detect and identify CDL products connected to it,
  and configure itself accordingly.
• MiniTXT
• The MiniTXT is an LED matrix display which can
  read attitude strings from various pieces of
  equipment and display the information either in a
  field by field manner or by scrolling the text.
  The unit consists of 6 8x8 LED matrices which are
  available in Red or Green.
• The MiniTXT has adjustable brightness and
  optically isolated comms capable (through serial
  command) of accepting RS422 or RS232 data
  levels.  Input baud rate is controllable up to
  38,400bps.
• Command/control software
• CDL maintain a small software development
  department who have expertise in the control of
  CDLs product line and the display of the data
  generated by our range of products. In addition
  we have a number of specialised software systems
  which can be used for inertial navigation in a
  wide variety of scenarios including seafloor
  positioning and flooded tunnel mapping.
• CDL can rapidly develop software systems to
  client specifications for use with the wide range
  of CDL products. Existing code libraries mean
  that this is a rapid and low cost process.

CDL Special projects

• Client specified special projects
• CDL regularly provide turnkey solutions for
  clients in a large number of subsea areas. We
  can provide solutions to almost any subsea sensor
  or control requirement.
• Wide range of existing products
• Given CDLs wide range of existing products, we
  are able to utilise our own off the shelf
  sensors to save on development time.
• In house multi-discipline development team
• Our team are highly flexible and trained in a
  large number of electronic and mechanical design
  disciplines including embedded systems, algorithm
  development, PCB design, firmware coding and many
  others.
• Fast turnaround
• Time is always short for special projects. Our
  existing code libraries and familiarity with our
  own products line allows rapid development of
  bespoke solutions.
• Tight deadlines
• We always work to deadlines, we have a team of
  supporting suppliers for metal work, machining,
  PCBs and other parts that we can trust. Our in
  house team are fast and efficient. Our special
  projects can be surprisingly low in cost

CDL Inertial Development

• CDL have a team of inertial design engineers with
  a deep understanding of the mathematics used in
  the design of aided inertial navigation systems.
• Our team are capable of adapting the existing CDL
  product range to the exact requirements of the
  customer by optimising algorithms and making
  firmware enhancements.
• Our 3 axis rate table is used to test all our
  mathematical models and ensure that our products
  perform as well in the real world as they do in
  simulation.
• Inertial navigation is the future of subsea
  positioning. Increasing water depths mean that
  installation and recovery of acoustic beacons
  becomes more and more expensive.
