Acoustic Doppler Current Profilers or ADCP’s are often used to measure ocean currents in specific areas
like shipping channels, around oil & gas facilities and marine mammal migration routes.
Application Note:
Ocean Current Survey
ADCP’s are generally deployed by fixing them to the bottom of manned vessels or attached to buoys that
are fixed in place. The former is operationally expensive while the latter limits measurement to a small
sample area.
Recent advances in ADCP technology have producednits that are smaller and more powerful. The new
devices lend themselves well to installation on small u, long-range unmanned vessels such as the
Submaran. These unmanned vessels or “gliders” allow much lower cost of operation and much higher
flexibility with regard to location and area coverage.
A wide range of data can be gathered by combining the ADCP with additional sensor systems. Wave
motion/height, water temperatures, salinity and other oceanographic and meteorological data can be
simultaneously transmitted via advanced line of sight and satellite communications.
Because of their very low speed of operation, less than 2 knots in many cases, gliders have proven only
marginally effective in many ADCP operations. The higher current speeds can cause them to drift and
require additional algorithmic correction when analyzing survey data. In addition, many gliders have
limited power available for ADCP operation requiring manual intervention to re-charge and re-purpose the
gliders. Finally, adverse weather conditions limit the window of operations of surface gliders.

Marine Protected Areas
Concern about the health and habits of the marine universe extends across commercial, scientific and
government sectors. Because of their importance to the ocean ecosystem, marine protected areas are
being established around the world in order to mitigate the damage done by years of inaction. The
Submaran provides an excellent, non-obtrusive and highly mobile platform for documenting activities in
marine protected habitats and other sensitive EEZ areas.
Monitoring of marine protected areas and identification of intruders is accomplished by equipping the
Submaran with sensitive hydrophones tuned to "listen" at specific frequencies. On board computers apply
algorithms that filter out various noise and make accurate identifications. Advanced third party software is
also able to differentiate between threats. Tracking information is then communicated via Iridium satellite
link to a base station accessible via internet. The system can be programmed to communicate at specific
intervals or trigged by activity level changes or both. Additionally, the Submaran can also be equipped
with camera systems to provide visual confirmations.
With the Submaran, additional sensor data can be combined with tracking data. Collecting information
from salinity and temperature monitoring systems, providing exact GPS locations and filtering data to
facilitate efficient communications of critical files.
Because of it’s ability to submerge and avoid harsh weather, the Submaran can remain on location
monitoring activity for long periods of time even in the worst conditions. Once the weather clears, the
Submaran can surface and up-load stored data.

Marine Mammal Tracking
Concern about the health and habits of the marine mammal universe extends across commercial, scientific
and government sectors. Because of their importance to the ocean ecosystem, whales and other marine
mammals are actively sought out and tracked around the world. The Submaran provides an excellent,
non-obtrusive and highly mobile platform for documenting marine mammal habits and patterns.
Marine mammal location and identification is accomplished by equipping the Submaran with sensitive
hydrophones tuned to "listen" at specific frequencies. On board computers apply algorithms that filter out
various noise and make accurate identifications. Advanced third party software is also be able to
differentiate between species. Tracking information is then communicated via Iridium satellite link to a

Gateway Communications
Gathering information from instruments and vehicles that operate on or near the sea floor can be a time
consuming and costly endeavor. Although acoustic under water modems allow for transmission from
depth to the ocean surface, receiving, recording and re-transmitting the data often involves manned
platforms. The Submaran provides gateway communications options that can be deployed more
frequently at a fraction of the cost.
The Submaran utilizes acoustic transceiver technology to communicate with deep sea systems and
accumulate the data on an on-going basis. The Submaran can store vast amounts of accumulated data
and utilize satellite communication to upload information on a regular schedule allowing for immediate
and consistent delivery of time sensitive data collected at the sea floor.
With the Submaran, various applications become widely deployable and affordable. Collecting information
from pressure and temperature monitoring systems, providing exact locations from GPS for precise
location of sea floor systems and collecting data from other unmanned underwater vehicles that would
otherwise have to surface to communicate or be recovered for downloads.
Because of it’s mobility, the Submaran can be used to collect data from large numbers of embedded sea
floor and/or underwater vessel systems. Because of it’s ability to submerge and avoid harsh weather, the
Submaran can remain on location and gather data for long periods of time even in the worst conditions.
Once the weather clears, the Submaran can surface and up-load stored data.

Surface/Sub-surface
Operations
The Submaran UUSV is uniquely designed as a hybrid underwater and surface unmanned system. The
ability to operate on the surface as a wind and solar powered glider and convert to a hydrodynamic
underwater vehicle will add a new dimension to group interoperability. The ability to deploy the same
vessel configuration for operation from the surface down to 200 meters using compatible command,
control and communications greatly simplifies the task of operating in groups over wide swaths of open
ocean.
There is a clear benefit for operators to be able to seamlessly command, control, exploit and share sensor
information from unmanned systems operating in both surface and sub-surface domains. Since the
Submaran is two vessels in one, there are fewer disparate systems to be concerned with when operating
in surface/sub-surface group configurations. Each Submaran will run the same operating system,
communications suite and be, characteristically, the same.
With Submarans working in groups, operators can take advantage of the ability to “swap” vessels
between surface gateway and sub-surface monitoring posts allowing each vessel time to re-charge via
solar panel. This will greatly extend the operating duration and range of the group as a whole.
Additionally, if more vessels are needed above or below, the command to re-purpose can readily be
passed from a primary gateway vessel to other vessels both above and below the surface.
Although it is recognized that the Submaran must be capable of communication with unmanned systems
from other vendors, the advantages of a single system operating in surface/sub-surface groups will
simplify operational requirements for deployment, control, sensor compatibility and maintenance.
Submaran Advantages
Compatible Control: Because it is one system operating effectively as
two there is no problem with cross compatibility or disparate
operations.
200 Meters
Group Mission Duration: Scavenging power at sea allows for very long
operational timeframes. The ability to “swap” functions between
vessels allows for each to operate a adequate power levels.
Hybrid Operations: One surface/sub-surface vessel system will reduce
operational concerns and reduce long-term maintenance, training and
handling costs.

Over the past several years, many have chosen to deploy unmanned maritime systems because of the
obvious advantages of lower cost and keeping people out of harm’s way. While the use of AUV’s and
other unmanned systems can cut operational costs for many applications by as much as 60 – 80%, the
capital and operational costs of training operators, data acquisition infrastructure and maintenance can be
prohibitive. To meet the market needs and relieve users from these capital and overhead costs, the
industry has begun to move toward offering operational services. Ocean Aero believes that this
operational service model is poised for rapid growth and is developing its own Robot as a Service (RaaS)
model that will leverage the performance of our Submaran UUSV.
