The ‘all in one’ portable single beam echo sounder and GPS survey solution for any boat anywhere.
CEESCOPE™ is a state of the art portable hydrographic surveying system with advanced capabilities in a truly compact package. Coupling powerful built-in RTK GNSS with a survey grade echo sounder in a single waterproof enclosure, it represents the ultimate in shallow water single beam survey systems.
Survey grade echo sounder data including a full water column echo envelope are combined with GNSS position in a simplified and easy to use one-box solution for hydrographic surveying. On-board GNSS receiver options from Trimble, Hemisphere, and NovAtel provide flexibility to meet varying survey and budget requirements. The CEESCOPE™ RTK includes a built-in RTK GNSS and UHF radio modem, allowing incorporation into existing RTK base station networks with no additional hardware on the survey boat.
The CEE ECHO™ and CEESCOPE™ echo sounders can log soundings at up to 20 Hz, providing exceptional bottom detail along the survey track. In addition to the sounding depth output, the complete sonar echo return from each ping is digitized into 3200 separate and discrete values from just below the surface to the sub-bottom level. The intensity of the echo return from the entire water column and sub-bottom is recorded, not just the single sounding depth value for each ping. When it comes to reviewing data quality in real time and after the survey is completed, the echogram record presents a crucial advantage over basic echo sounders that output only the digital depth sounding value. For example, heavy bottom vegetation may be identified on the echogram and differentiated from the true bottom, a process that may be impossible with a basic echo sounder.

With the CEESCOPE™, the surveyor can simply get on with the job of collecting accurate bathymetry. The ultimate CEESCOPE™ package includes an RTK GNSS receiver and Satel UHF radio modem, all in a compact portable one-box package. Connection to a local base station is possible without the need for any additional hardware in the field, minimizing the setup time, eliminating radios, cables and batteries. Just turn on and start surveying!
All of the CEESCOPE™ functions may be accessed through an LCD touch screen, and CEE CONNECT control software utility, making the unit setup and configuration easy. For surveying when a laptop is not desired, such as on a personal watercraft, the internal memory or an external USB flash drive can be used to record the entire survey – including the full water column echogram.
The CEESCOPE™ can be specified with the latest OEM GNSS options from NovAtel, Hemisphere GPS, and Trimble to ensure all accuracy requirements are met. For surveying at the submeter level, a range of receiver options provide 0.1 – 0.5m accuracy, with optional L-Band corrections for survey locations without SBAS service. RTK positioning is available for users requiring cm-level accuracy or GNSS elevation (tide) data. The use of 1 pulse per second (PPS) timing from the on-board GNSS receiver offers precise time stamping for the complete dataset collected by the CEESCOPE™. This ensures all soundings taken between GNSS location updates are accurately positioned.
Watch the mobilisation of a Jon boat with the CEESCOPE™ RTK echo sounder system. Simply connect the transducer, GNSS antenna, and laptop and start surveying.

FIELD APPLICATION NOTES:
The non-RTK CEESCOPE™ GNSS positioning solutions are based on the Hemisphere Eclipse OEM receiver that can utilize Atlas L-Band corrections. Offering worldwide differential corrections broadcast from L-Band satellites over the equator, the Atlas system offers CEESCOPE™ users various levels of accuracy to suit the geographic location and the survey project requirements. All CEESCOPE™ systems are shipped with the multi constellation, dual frequency A42 antenna allowing users the ability to upgrade their positioning accuracy with no limitation caused by the antenna.
All CEESCOPE™ echo sounders with built-in Eclipse GNSS receivers may be configured by the user with any of the accuracy levels available, simply by loading a firmware activation file. So, the most basic CEESCOPE™ can be later upgraded to the highest performing option if necessary. From the factory, CEESCOPE™ echo sounders may be configured as follows:
Option 1: CEESCOPE ECLIPSE SBAS
The most basic CEESCOPE™ option has an advanced Eclipse OEM GNSS receiver inside, ready to be activated for any of the L-Band services but it is supplied with no activation loaded. This configuration is appropriate for users in regions with free SBAS corrections (eg WAAS, EGNOS) and will allow submeter positioning without the need for any Atlas L-Band signal.
Option 2: CEESCOPE ECLIPSE ATLAS-BASIC
The Atlas BASIC upgrade adds key advantages. For a low cost “lifetime” subscription loaded at the CEE HydroSystems factory, the Eclipse GNSS receiver is activated to receive L-Band corrections generated from Hemisphere’s global network of over 200 reference stations. Even for users in SBAS-enabled regions, the BASIC upgrade will provide better positioning quality through an increased number of satellites available for the solution; the Atlas BASIC L-Band differential corrections can include multi constellation data not available to SBAS systems.
For users in areas with no access to free SBAS signals, such as Africa, South America, Asia, and Australasia the Atlas BASIC provides a great positioning option, and avoids the need to otherwise rely on 3m+ autonomous GPS quality. With 0.5m accuracy possible anywhere in the world, Atlas BASIC provides horizontal positioning accuracy adequate for most hydrographic projects. Vertical position data from Atlas BASIC is not accurate enough for incorporation into hydrographic datasets.
Option 3: CEESCOPE ECLIPSE ATLAS H-10
A separate time-limited subscription to the the Atlas H-10 L-Band correction service activates the multi constellation dual frequency L1/L2 receiver operation, and the Atlas corrections themselves. The H-10 signal may be activated at the factory for 1 year, 3 years or 5 years of L-Band signal. The user may also later activate these subscriptions, or shorter period subscriptions for single projects. When fully converged, the H-10 signal will provide accuracy better than 10cm. The Hemisphere Atlas L-Band approach allows the user to minimize capital investment in GNSS equipment, and only pay for required accuracy when needed. With easy subscription ordering and receiver activation procedures, the Atlas system is convenient and budget-friendly.
Using the Atlas L-Band correction service brings the benefits of multi constellation positioning to the CEESCOPE™ surveyor. Even with badly obstructed skies, for example near tree canopy during narrow river surveys, position tracking is solid. However, one drawback with any precision L-Band signal such as H-10 is the time needed to converge on an accurate solution. The GNSS system will need a fairly lengthy period (around 20 minutes) to reach the maximum level of accuracy, however the Atlas BASIC service at a lower accuracy level converges quickly.
These latest multi frequency NovAtel OEMV7 receiver options offer centimeter-level precision and accurate elevation measurements for recording of “RTK tides”. Both options allow internal recording of raw GNSS pseudorange data for post processed precise positioning using Continuously Operating Reference Station (CORS) derived corrections.
NovAtel 729 – Multi frequency 555-channel L1/L2/L5 GNSS receiver with internal RAW data recording to allow post processing to an accurate solution without the need for a local RTK base station. with L-Band corrections for better than 10 cm accuracy with a subscription to the TerraStar corrections service. The L-band option is typically selected where free SBAS or beacon corrections are unavailable and it is not practical or necessary to set up a local RTK base station. Supplied with the NovAtel GPS-702-GGL antenna.
NovAtel 729 RTK – As above with RTK capability, allowing the CEESCOPE™ to connect to a local RTK base station and receive real time kinematic differential corrections for cm-level precision. Typically selected when water surface elevation (tide) is being measured using the satellite positioning system and not traditional (eg tide gauge) methods.

– Can I connect an external GPS / GNSS receiver?
Although the CEESCOPE™ has a built-in GNSS, it is possible to feed in position data from a separate receiver. Simply match the CEESCOPE™ input port settings to the external receiver.
– What is the difference when using an external GPS / GNSS receiver?
The CEESCOPE™ combined data output stream is identical, however the time stamping process requires the $GPZDA message to be exported from the external receiver to synchronize the CEESCOPE™ to GPS time. When using the CEESCOPE™ internal GNSS, all timing is set by a more precise 1PPS signal.
– Can I use RTK GPS?
Yes. RTK can be used with the CEESCOPE™ to generate a bottom elevation point cloud in the hydrographic survey software, consistent with the local grid coordinates and vertical datum. This may be with the internal RTK GNSS option or an external RTK receiver.
– Can I connect to an RTK base station?
Yes. The RTK CEESCOPE™ has a UHF radio modem that can be set to connect to your local base station, avoiding the need for any radios on the survey boat.
– Can I use NTRIP / cell phone corrections
Yes. The CEESCOPE™ can accept differential corrections from a cell phone VRS network, using the hydrographic survey software broadcaster for example.
– How long does the battery last?
The rechargeable battery will last 8 hours in operation, although this can be extended by turning off the touch screen display when not required.
– How long does it take to recharge the battery?
The battery will recharge in 4 hours. The battery will NOT recharge unless the unit is powered off.
– Can an external power source be used?
Yes. Any 12-24V supply may be used. –
What is the maximum depth achievable?
CEESCOPE™ 200 – 200m for both 33 kHz and 200 kHz transducers. CEESCOPE™ 100 – 100m for both 33 kHz and 200 kHz transducers.
– Can I use my own existing transducer, eg Odom?
Yes. We can supply patch cables for third party transducers with Amphenol connectors.
– How is the transducer mounted?
The transducers can each be supplied with a matching mount that will fit standard 50mm OD pipe. The transducer cable is passed up the inside of the pipe to prevent damage
– Can I use 24 kHz transducers?
Yes. The CEESCOPE™ is designed for transducers close to 33 kHz or 24 kHz.
– How waterproof is the unit?
A special custom manufactured lid seal is used to ensure water cannot penetrate through the box and the seal will remain intact after years of use. Waterproof rugged LEMO cable connectors are used.
– Do I need an acquisition computer?
No. While the CEESCOPE™ is often used with a laptop collecting the data in real time, it has internal memory allowing collection of all data with no connected PC. This also serves as a useful backup data log.
– Can I use a hand held data collector, such as Trimble TSC2 or TSC3?
Yes. The Bluetooth data output from the CEESCOPE™ may be accepted by land survey data collectors after pairing the devices. Depth measurements from the CEESCOPE™ may then be stored in a point data file with GPS data.
– How do I take data off the CEESCOPE™?
Inserting a USB flash drive into the USB port will cause data to be automatically copied onto the external USB.
– How do I change the CEESCOPE™ settings?
All the settings are available through the touch screen display with a simple on-screen menu system. A computer is not required to change any of the CEESCOPE™ settings, however the CEESCOPE CONNECT software utility allows settings to be changed through a connected PC.
– Can I change the echo sounder sonar settings?
Yes. The high and low frequency channels can be independently adjusted in terns of pulse width, gain, detection threshold, blanking distance, and maximum depth to follow the desired bottom surface.
– How do I conduct a bar check?
The CEESCOPE™ has a special bar check routine to make it easy to conduct a calibration check. A connected PC is not required to complete this procedure.
– Can I adjust sound velocity (SV)?
Yes. Enter the SV value directly into the CEESCOPE™, or input the temperature and salinity and the SV will be calculated.
– What are the output formats?
The CEESCOPE™ outputs a proprietary output format including GPS position, sounding depths, and a full water column echogram binary packet file in a time-stamped data stream. Other industry standard formats may be selected such as DESO25, Odom SBT / DBT, NMEA0183.
– What software package is required?
The CEESCOPE™ will work with all available hydrographic acquisition packages. The package used must contain a driver for the CEE HydroSystems digital echogram to be able to see the water column envelope. HYPACK® is the most suitable option.
– Where do I mount the transducer?
The transducer ideally should be mounted half way between bow and stern to minimize motion from waves, and should be braced with ropes fore and aft to prevent movement in the water. The minimum draft should be 50cm from the water surface to the transducer face, or slightly above the keel depth.
– What is the typical survey speed?
Usually 4-6kts. Surveying at over 8 kts may cause issues with air bubble entrainment.
– Can I mark points of interest / events?
Yes. The “event” button creates a sequential event number in the data record, associated with the exact position and depth when the button is pressed.
– Can I use the CEESCOPE™ with an ADCP?
Yes. The GPS and/or depth data may be routed to an acoustic Doppler current profiler such as the Teledyne RD Instruments River Ray, River Pro, and Rio Grande to collect simultaneous velocity measurements.
