OEM & Custom Instruments

AvTrak 6 OEM UAV Tracking & Communications Module

Accurate AUV Tracking & Navigation

AvTrak 6 OEM UAV Tracking ModuleDesigned for 12 and 21 inch class AUVs, the AvTrak 6 combines a USBL transponder, LBL transceiver and modem into one low-power unit that provides absolute position reference data for AUV inertial navigation systems (INS). The unit is capable of broadcasting robust telemetry for AUV to vessel and AUV to AUV communications.

The instrument is available in different configurations, with integral or remote transducer options, directional transducer and high power (HP) variants, and depth ratings of up to 7000m. An OEM version is available without housing, for integration into existing equipment.

AvTrak 6 Nano OEM Integrated Tracking System

Miniature transceiver for small AUV & ROV tracking

AvTrak 6 Nano OEM Integrated Tracking SystemThe AvTrak 6 Nano OEM is specially designed for smaller unmanned underwater vehicles such as ROVs and AUVs. Providing many of the features supported by the larger AvTrak 6 transceiver, the system has a depth rating of up to 995m and features an integrated Li-ion rechargeable battery that provides up to 10 days emergency standby life for extended relocation and recovery opportunities.

The AvTrak 6 Nano OEM is compatible with Sonardyne’s Mini-Ranger 2 6G Wideband USBL system and supports the standard 6G command language as well as Sonardyne’s Messaging Service (SMS) telemetry, thus providing an integrated navigation and data link vehicle solution in a single instrument.

Subsea Navigation Sensors

Syrinx Subsea Doppler Velocity Log

High accuracy AUV & ROV navigation

Syrinx DVL Doppler Velocity Log with integrated ADCPThe Syrinx Doppler Velocity Log (DVL) is a 600 kHz system designed for both unmanned surface and subsurface vehicles that can be used as a standalone DVL, as part of an integrated system, or perform both functions at once.

This dual capability means that only one DVL/altitude sensor is required for both ROV control and survey crews, saving on cost and payload space.

Syrinx can be integrated with Sonardyne’s SPRINT INS to provide superior DVL-aided navigation, with enhanced velocity prediction and redundant positioning capability. Syrinx also features a robust low-altitude mode that provides high accuracy and high output rates even when operating at altitudes of less than 1m.

Syrinx is supplied with a 4000m-rated titanium housing as standard, with 3000m, 6000m, and OEM (no housing) versions also available.

SPRINT Subsea Inertial Navigation System

Survey quality inertial navigation for ROVs & AUVs

SPRINT Subsea Inertial Navigation SystemIdeal for ROVs and AUVs, the SPRINT is an acoustically-aided subsea Inertial Navigation System (INS) that optimally processes data from USBL, LBL positioning, Doppler Velocity Log and pressure sensors to improve position accuracy, precision, reliability and integrity.

Combining an AHRS (Attitude Heading Reference System) with an AAINS (Acoustically Aided Inertial Navigation System) allows subsea inertial navigation to start or restart instantaneously on receipt of a position update, avoiding a lengthy alignment period.

The SPRINT hardware platform maintains a rolling 15 day backup of all real time navigation and raw data on an onboard SD card.

SPRINT-Nav Subsea Navigation Sensors

Combined INS and DVL for accurate ROV navigation

SPRINT-Nav Subsea Navigation SensorsSPRINT-Nav is an all-in-one system that combines the SPRINT INS sensor and Syrinx 600 kHz Doppler Velocity Log with a high-accuracy intelligent pressure sensor to provide high-performance subsea navigation for underwater unmanned vehicles. It is available in three different performance levels as well as two different depth ratings of 4000 and 6000 metres.

SPRINT-Nav Mini is an ultra-compact hybrid acoustic-inertial navigation system that is ideal for observation-class and work-class ROVs as well as unmanned underwater vehicles operating in GPS-denied environments.

SPRINT-Nav Mini hybrid acoustic-inertial navigation systems

Using the same proven algorithms as the larger members of the SPRINT-Nav family, the SPRINT-Nav Mini tightly fuses its sensor outputs to provide high-precision orientation, velocity, altitude and depth data. The single compact unit replaces the need for AHRS, DVL and pressure sensors, with less cabling, fewer connectors and simpler operation.

SPRINT-Nav Mini is available as either a 300 metre or 4000 metre depth rated unit.

USBL Acoustic Technology

Ranger 2 Subsea Positioning (USBL) System

Remote AUV & ROV tracking and communication

Ranger 2 USBLDesigned for deep and shallow-water tracking of subsea vessels and with an operating range of greater than 7000m, the Ranger 2 is a high-performance USBL (Ultra-Short Base Line) subsea vehicle positioning system that provides an optimal accuracy of better than 0.1%. It is compatible with all DP (dynamic positioning) systems on the market.

Ranger 2 can simultaneously track multiple subsea targets or transponder nodes and upload data to the surface with high-speed communications. It is ideal for a wide range of ROV or AUV missions including surveying, ocean science and seismic exploration.

The Ranger 2 USBL tracking system can be installed on USVs to remotely track the position of underwater targets, such as AUVs, and communicate with them.

The capabilities of Ranger 2 can be extended even further with optional Survey, Dynamic Positioning and Professional add-on packs.

Solstice AUV Side-Scan Sonar

Ultra-high resolution Multiple Aperture Sonar for AUVs

Solstice Sonar for AUVs

Solstice is a Multi Aperture Sonar (MAS) system designed for high-precision AUV missions such as Search, Classify and Map (SCM), hydrographic surveys and mine detection.

Solstice AUV Side-Scan SonarCapable of producing high-fidelity imagery and with an industry-leading along-track resolution of 0.15°, Solstice provides superior performance even in very shallow water, and consumes only 18 Watts of power, making it ideal for extended unmanned missions.

Powerful onboard processing produces geo-coded side-scan imagery for integrated Computer Aided Detection and Classification (CAD/CAC) and Automatic Target Recognition (ATR). A vertical hydrophone array on each flank delivers high-quality bathymetry data which can be used to produce extremely detailed digital terrain maps.

This high resolution imagery was collected by the Solstice AUV sidescan sonar:
