Get the SPRINT advantage

SPRINT gives you:

• Robust performance in challenging subsea conditions
• High-precision outputs for enhanced vehicle control
• Instantaneous start-up without lengthy alignment periods
• Seamless integration with your existing equipment

SPRINT optimises acoustic aiding data from USBL, LBL, Doppler Velocity Log (DVL) and pressure sensors, improving position accuracy, precision, reliability, and integrity. It extends the operating limits of your vessel’s USBL and enhances LBL efficiency by enabling sparse seabed transponder arrays. All while reducing operational time and vessel costs.

Choose your SPRINT

• SPRINT 300: Perfect for dual ROV and survey use, standalone ROV guidance, and mid-water station keeping. It’s the most cost-effective subsea INS available, with less than 0.1° Sec Lat Heading accuracy.
• SPRINT 500: Ideal for your demanding multibeam survey operations. Supports tightly integrated sparse LBL range aiding from Sonardyne 6G transponders, with automatic pressure and swell compensation.
• SPRINT 700: Our highest-performance INS system, designed for your most challenging subsea survey tasks. Supports mobile laser mapping and acoustic inertial metrology with tight integration to Sonardyne acoustics.

The technology

Inertial navigation is inherently self-contained and robust with very good short term accuracy, but it can drift over time. Therefore, the SPRINT INS is supported by complementary acoustic positioning to provide long term accuracy and robustness. This significantly reduces operational delays during periods of challenging subsea acoustic conditions such as aeration and noise. The precision and update rate of the output allows greater subsea vehicle control and makes SPRINT suitable for ROV station keeping.

SPRINT shares a hardware platform with our Lodestar AHRS and runs both AHRS and INS algorithms concurrently. This allows instant INS start or restart upon receiving a position update, eliminating the lengthy ‘alignment’ period common in other systems. The system monitors AHRS and INS orientation separately to assess its health. All calculations are performed internally, protecting against communication issues. The system maintains a 15-day backup of navigation and raw data on an onboard SD card, while topside software concurrently logs all data, ensuring data integrity.

DVL and AHRS/INS

Our Syrinx DVL provides tight beam-level aiding to SPRINT, giving superior positioning performance even with partial beam availability. Standalone 3rd generation SPRINT and Syrinx DVL can be joined together for pre-calibrated, interchangeable use, or combined into the compact SPRINT-Nav unit. This integrated solution, optionally including an internal pressure sensor, is suitable for various ROV and survey tasks. The combined unit features depth-rated water blocks for each transducer to protect the internal components and when supplied together typically doesn’t require re-export licensing, simplifying your shipping logistics.

Designed and manufactured entirely in the UK, Syrinx is a class leading DVL for surface and subsea vehicles, available in two frequencies: 600 kHz or 400 kHz for higher altitude tracking up to 230 m. Syrinx variants combine high resolution and high altitude tracking, in single, easy to install navigation instruments. Its adaptive bottom lock technology provides consistency and reliability over challenging and changing topography, working at an altitude higher than 85% of the world’s subsea infrastructure. This reduces the amount of time a vehicle must dive on free inertial.

If your mission requires water profiling, Syrinx’s highly capable ADCP mode enables both navigation and profiling without the need for separate instrument, saving you cost and payload.

When tightly integrated with Sonardyne’s SPRINT INS, unmatched DVL-aided navigation can be achieved. This allows for enhanced performance through optimisation of beam-level data passed between Syrinx and SPRINT to aid velocity prediction and outlier rejection, with positioning able to continue even if one or two DVL beams are unavailable. For the ultimate integration Syrinx and SPRINT are also available as a single combined unit with integral pressure sensor. SPRINT-Nav is one of the smallest inertial DVL instruments available on the market suitable for almost any ROV and survey task.

Why Syrinx?

• Unmatched Versatility: Use Syrinx as a DVL, ADCP, or both simultaneously. You decide how to harness its power.
• Deep-Water Performance: Maintain solid bottom lock up to 230 m, with 4,000 m depth rating as standard.
• Adaptive Technology: Our smart bottom lock ensures reliable navigation across varied seabed types.

Dive deep, control smart

Syrinx runs an embedded system manager using a web browser, eliminating the need to install dedicated PC software. This allows configuration and testing of Syrinx prior to deployment, control during subsea operations and visualisation of the navigation data.

The hardware and vehicle interfacing are easy to install, set up and use. It’s compatible with DVL/ADCP mounting arrangements from other vendors so you shouldn’t need to modify your subsea vehicles to upgrade to Syrinx. PD0, PD3, PD4, PD6, PD13 telegrams are supported for integration to third party navigation systems.

A 4,000 m rated titanium housing is supplied as standard to meet the requirements of work-class ROVs. 6,000 m and OEM (no housing) versions are also available.

Syrinx’s transducers have been designed, built and tested in-house to provide maximum performance, and can be individually replaced, reducing ownership costs and repair time. The entire array is water blocked meaning that should damage occur to the transducer array, the unit’s electronics are isolated from water ingress.

Echo Observer for Syrinx (EOS)

EOS is a software application for Syrinx and SPRINT-Nav systems which allows ADCP data to be viewed, quality controlled, logged and then exported. This standalone application is compatible with Windows 7 or 10 and requires only modest processing resources.

EOS provides an intuitive interface to Syrinx, allowing the device to be configured over Serial port or Ethernet with a quick setup procedure for ADCP measurements. You can immediately view the profile data and make any necessary adjustments before committing to a long-term deployment.

Once initial data inspection has been completed, EOS provides the link to the onward data processing chain: Industry-standard PD0 data can be exported as comma-separated variable (CSV) files, ideal for importing into Excel or Matlab for analysis and post-processing. The exported PD0 data can be tailored to match your analysis needs, such as specific portions of the water column, or a favoured frame of reference.

Specific sections of the PD0 data can be omitted in CSV export if they are not relevant to your analysis, reducing file size and therefore processing time. Echo Observer for Syrinx is included with the ADCP functionality upgrade for both Syrinx and SPRINT-Nav.

Make time-critical decisions with near real-time data delivery

Analyse the structure of your velocity and backscatter intensity data in far finer detail than previously possible with our proprietary formats delivering up to ten times greater spatial resolution. Origin 600 delivers conventional PD0 data as standard, whilst logging the higher resolution data to further enhance your results. All data is recorded to the onboard storage unit with 1 TB capacity.

Reduce your risks and device retrieval costs with power-efficient electronics and a rechargeable internal battery which allows deployments of up to three months on a single charge. A dual battery option allows you to operate longer or more energy demanding deployments. External power can be supplied by PoE, allowing you to program and download data without a separate power supply.

Monitor waves, mean currents and turbulence using Origin 600’s five-beam configuration and sampling frequency of up to 4 Hz on all beams. Your Origin’s built-in acoustic modem enables you to remotely access the unit while it’s deployed using an accompanying topside modem (sold separately) and the Origin Topside PC software. This allows you to check battery and storage, inspect and upload data, reconfigure schedules and run quality control, all whilst your ADCP is on the seabed.

Add external sensors to your ADCP mounting frame, and fuse with your Origin data via the Edge processing software, to really get the most out of every single deployment. You can upload sensor apps via Origin Portal or Topside and the resulting data will be exported over the acoustic modem.

What is Edge?

Discover the key to your customised ADCP data…

A suite of intuitive software tools and the Sonardyne Edge computing environment allows you to get the most out of your Origin 600. The Origin Portal web UI lets you configure your ADCP in operational conditions, including modification of the sampling schedule. Reduce your operational risks by setting your schedules before deployment using the Origin Scheduler PC application. Two schedules can be run together, allowing dual monitoring tasks to be performed with a single device. File data can be inspected using the Origin Viewer software package.

Origin 600 is compatible with your standard mounting infrastructure, reducing your risk and cost for upgrading to this device. For a complete solution, we can provide a dedicated, rugged stand with space for dual redundant releases.

An innovative, robust acoustic design

Its pioneering satellite-dish design allows Origin 65 to match or exceed the acoustic performance of competing instruments. All while reducing your costs, prolonging battery life and increasing robustness to pressure cycling – a long-standing problem with low-frequency ADCPs.

Connect to the subsea world – integrated modem and PIES

Check or reprogramme your Origin 65 acoustically while on the seabed via its integrated acoustic modem. There’s no need to retrieve the device or interrupt your operation.

During your operations, Pressure Inverted Echosounder (PIES) measurements are interleaved with current profiles. This allows time-of-flight (TOF) and average sound velocity (SV) to be determined in-situ alongside the ADCP sampling and the data fused in PD0, delivering all data time-aligned in one place.

At the end of a deployment, the modem can be used to trigger the integrated acoustic release, allowing the device to float to the surface for retrieval.

Don't just settle for standard – introducing A-gram and B-gram data

Your Origin 65 delivers industry standard PD0 data format as default, but why settle for standard when you can have up to ten times greater resolution?

Origin generates our exclusive A-gram and B-gram formats. These offer up to ten times greater spatial resolution than PD0 and expose raw acoustic data which you can them interrogate for your specific operations.

Origin ADCP – Edge enabled

Edge lets you run data processing apps on Origin 65 which are customised to your exact needs. The system will produce the information you are most interested in, rather than bulky raw data that would normally be processed once the device is recovered. You can harvest this data as a file or as a live stream, either through a cabled connection or Origin 65’s integrated acoustic modem.

What is Edge? Discover the key to your customised ADCP data…

Edge computing gives you the ability to write your own apps for Origin via our Software Development Kit (Edge SDK) so that you can focus on the data you need from your operation. To get you started, some of the apps already available to download include simple background currents and quality metrics.

Data gathered by your Origin can also be processed to your requirements within Edge before it is harvested. This minimises both the amount of unnecessary data in each upload and the time taken for each harvest.
