Small in size, big in performance
AvTrak 6 Nano may be our smallest acoustic transceiver, but its features and performance are anything but.
It’s built on the same 6G hardware and Wideband 2 digital signal architecture found in its larger cousin, AvTrak 6, all packed into the smallest possible form factor.
Use it with our popular MF USBL Ranger 2 family to track your AUVs or seafloor nodes. Then use the Sonardyne Messaging Service (SMS) to exchange status messages with the USBL or other AvTrak 6 Nanos in your vicinity. With hundreds of units in the field, AvTrak 6 Nano is ideal for AUV swarms.
Like its larger cousin, AvTrak 6 Nano has been developed to meet the requirements of a wide variety of AUV mission scenarios, vehicle types and the operational demands for different industries.
For energy – it’s not just for AUVs. Integrate AvTrak 6 Nano with your seabed nodes and you have a network of sensors that can position and communicate with each other.
For defence – its small form factor and ability to enable surface to AUV or AUV-to-AUV communications, makes it a prime option for swarm or squad robotics operations.
For science – AvTrak 6 Nano enables an AUV to undertake simultaneous USBL tracking and telemetry with a research vessel, as well as AUV-to-AUV communications making your projects more cost and time efficient.
At a glance
- Tracking, communications, and emergency relocation in one instrument
- Use with Ranger 2 to track every move your AUV makes
- Bi-directional acoustic modem with user selectable data rates; 200-9,000 bps
- Wide voltage input range and multiple communication methods for robotics integration
- Optimised for Ranger 2 Robotics pack for aiding navigation systems with remote position outputs
- Housed variant or OEM for integration into vehicles
Mini but mighty
AvTrak 6 Nano measures just 192 x 55 mm, you won’t find a smaller AUV transceiver with this much capability. It has an operating range of 3,000 m, a depth rating of 500 m and full SMS and Modem functionality.
Going smaller still, AvTrak 6 OEM Nano redefines nano, measuring at just 95 mm x 43 mm. You won’t find a smaller OEM AUV transceiver with this much capability. Its omni-directional transducer is small too, at 49 mm diameter and 72 mm long.
Equipped with AvTrak 6 Nano, your AUV will receive unlimited data and share messages every navigation cycle when used with Ranger 2. By supporting the integration of a data payload inside every navigation signal, this allows more data to be transferred to and from AUVs with fewer transmissions which ultimately reduces power consumption and increases mission endurance.
A common configuration enables the USBL system to communicate with a squad of AUVs equipped with AvTrak 6 Nanos, broadcasting to all the position of each member of the squad to aid the navigation solution and improve their situational awareness. Each AUV then replies in sequence with status information.
AvTrak 6 Nano can also be used to enable AUV-to-AUV communications and choose from seven telemetry schemes ranging from 200 bps to 9,000 bps of effective user bandwidth. Either for short burst communications or full large quantity data upload from seabed monuments.

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.
- Dual-Frequency Options: Choose between 400 kHz for extended range or 600 kHz for high resolution.
- Seamless Integration: Syrinx works harmoniously with our SPRINT INS for unparalleled navigation accuracy.
- Efficiency: Combine navigation and water profiling in one instrument, saving you space and resources.
- Reliability: Individually replaceable transducers to minimise downtime.
- Adaptability: Available in 4,000 m, 6,000 m and OEM versions to suit your specific needs.
- User-Friendly: Web-based System Manager for easy configuration and control.
- Compatibility: Fits existing mounting arrangements and supports various data formats for smooth integration.
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.
Experience the Syrinx DVL advantage
Whether you’re navigating an AUV through complex underwater terrain or precisely positioning an ROV for critical operations, Syrinx provides the accuracy and reliability you need. Our adaptive technology keeps you on track over challenging topography, reducing reliance on inertial navigation.

Mini in size, big in performance
Small but mighty
Measuring just 213 mm in height (only fractionally taller than some competing DVL-only instruments), 148 mm in diameter and weighing in at approximately 3.6 kg in air for the 300 m rated unit – or 7.1 kg for the 4,000 m depth version – for something so small, SPRINT-Nav Mini packs a big punch for all your underwater ocean robot applications.
It’s powered by the same hybrid acoustic-inertial navigation algorithm you’ll find inside our established SPRINT-Nav family. This combines the strengths of all its sensors to provide robust, precise and accurate outputs. It continues to work even in challenging environments providing a continuous stream of positions, orientation, velocities, depth and altitude at up to 200 updates per second.
Ready to go
Your SPRINT-Nav Mini arrives pre-calibrated, meaning there is no need to manoeuvre your vehicle every time the unit is mobilised. SPRINT-Nav Mini does the thinking for you, all in a single plug-and-play unit. Turn it on, give it a latitude, and away you go.
Despite its extremely small size, it’s still a true north seeking gyrocompass which won’t drift over time unlike MEMS-based systems. The output can be fed directly to your own (or a third party) user interface or vehicle control software. The simple web user interface makes setup and configuration painless. It could not be any simpler.
Need to harvest data from coastal waters or around offshore structures? Not a problem! Low power and small, SPRINT-Nav Mini is ideal for installing on all size ROVs or USVs undertaking data harvesting missions, even in GNSS-denied environments.
Conducting marine research on a restricted budget? Let us help… Because it’s lower cost than the four separate sensors it replaces, SPRINT-Nav Mini is the budget-friendly solution for your research platforms where funds need to stretch as far as possible.
Available in two depth ratings, 300 m and 4,000 m. A side-connector option is also available, depth rated for 300 m and only 183 mm high, making it ideal for tight spaces on small platforms.

Navigate your marine environment with the confidence only SPRINT-Nav can provide.
Pinpoint location precision. Enhance your operations by adding valuable location detail enabling you to identify exactly where your data is drawn from or to pinpoint the location of assets, obstacles and pipelines.
Guide, control and navigate your USVs, ROVs and AUVs faster, safely and more efficiently with SPRINT-Nav. Operate your vehicles and vessels with the confidence of knowing exactly where they are and what they’re doing.
No calibration needed. Straight out of the box SPRINT-Nav is ready to go, saving you precious time on your operations.
Reduced in size – but not in performance, SPRINT-Nav Mini is the industry’s smallest all-in-one hybrid acoustic-inertial subsea navigator. It provides the perfect instrument for you to control your smaller inspection class ROVs and small to medium sized USVs.
Engineered for all autonomous vehicles no matter what size or purpose, there is a SPRINT-Nav for your operations.
Why should you invest?
By choosing SPRINT-Nav you are choosing an all-in-one acoustic-inertial navigation sensor, replacing the need for a separate DVL, pressure sensor and INS/AHRS. Saving you the time, cost, cabling and integration challenges associated with using different sensors from different vendors.
At a glance
- Unique to Sonardyne
- Performance levels to suit your operations
- Tightly integrates raw acoustic, Doppler and inertial data
- Titanium housed for deep ROV missions
- Outputs altitude, depth, orientation and velocity
- Configure and control using a Web UI
Compact
Low power and small, it’s the ideal size for installing on all size ROVs as well as USVs undertaking data harvesting missions in shallow water and around offshore structures which often block GNSS signals.
Cost-effective
Because it’s cheaper than the four separate sensors it replaces (AHRS, DVL, INS and pressure sensor), it’s a cost-effective solution for your research platforms where budgets need to stretch as far as possible.
Specialist applications
SPRINT-Nav X is the highest-grade model in our SPRINT-Nav family designed for very specialist applications such as long endurance missions using XLUUVs.
Survey
Supports dual ROV and Survey use and standalone ROV guidance. Also provides mid-water station keeping with vendor independent USBL aiding.
