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.

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.

GNSS OPTIONS

hemispheregnss_logo_solid_rgb_sm

 

These receiver options present cost-effective built-in positioning for applications where precise vertical elevation is not required and 0.5 – 2m position accuracy is adequate. Such applications include industrial water surveys, reconnaissance surveys, and volume calculations where water volume can be measured accurately without requiring precise absolute position:

Hemisphere Crescent Marine Beacon – Single frequency L1 GPS receiver for cost effective one-box “all in one” surveying where differential corrections may be supplied by free SBAS systems such as WAAS or EGNOS. May also be used with MSK marine beacon corrections for a differential (DGPS) solution. Standard configuration includes 10Hz position update rate. Supplied with the Hemisphere A43 antenna with beacon.

NovAtel OEMStar – Single frequency L1 GNSS receiver with GLONASS satellite tracking offering a more robust basic-level solution where there may be partial obstruction of the sky, such as under tree canopy. Standard configuration includes 10Hz position update rate. Supplied with the NovAtel GPS-701-GG antenna.

The latest Hemisphere Eclipse II GNSS receiver presents a new approach to obtaining accurate decimeter positioning anywhere in the world. The CEESCOPE™ ECLIPSE  is supplied with a basic level (L1 only) receiver card. A separate subscription to the the Atlas L-Band correction service activates the dual frequency L1/L2 receiver operation, GLONASS signal reception, and the Atlas corrections themselves.  This 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 approach 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.

For users in regions with no access to free SBAS submeter differential corrections such as South America, Asia, Australasia, and Africa, the Atlas service fills the gap where autonomous positioning (no differential corrections) is inadequate and RTK-level accuracy is either not required or not feasible from a cost perspective.

These multi frequency NovAtel OEMV6 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 628 – Multi frequency 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 628 RTK – Multi frequency L1/L2/L5 GNSS receiver 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.

For hydrographic surveying within existing Trimble® infrastructure, the CEESCOPE™ RTK-BD970 using the Maxwell™ 6 receiver technology will facilitate trouble-free connectivity with Trimble base station receivers. For users who are keen to maintain equipment consistency and interoperability, the Trimble CEESCOPE™ was developed to fit seamlessly into existing networks.

Compared to a conventional standalone echo sounder and separate GPS system, the CEESCOPE™ system presents several advantages.

For survey locations where a 200 kHz echo sounder may not adequately penetrate down to the bottom, the CEESCOPE™ 33/200 kHz or 24/200 kHz dual frequency upgrade adds a second channel offering greater penetration through water and loose sediment, sludge and silt. Commonly used on dredging-related surveys to distinguish the undisturbed bottom from the resuspended or redeposited material, the low frequency channel provides the added confidence that reported results are consistent with reality. With the dual channel full water column echo envelope displayed in real time and logged on hydrographic software, the dual frequency CEESCOPE™ can display a complex view of the bottom, with the 200 kHz data identifying the soft bottom and the 24 kHz or 33 kHz following the harder bottom surface underneath.

– 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.
