Subsea Navigation Sensors
Syrinx Subsea Doppler Velocity Log
High-precision AUV & ROV navigation
The Syrinx Doppler Velocity Log (DVL) operates at 600 kHz and is designed for both unmanned surface and underwater vehicles, functioning as a standalone DVL or as part of an integrated system.
This dual functionality means that only one DVL/altitude sensor is necessary for both ROV control and survey operations, optimizing costs and payload capacity.
Syrinx can be paired with Sonardyne’s SPRINT INS to enhance DVL-aided navigation, offering improved velocity prediction and redundant positioning capabilities. it also features a robust low-altitude mode that ensures high accuracy and output rates, even at altitudes below 1m.
Syrinx comes standard with a titanium housing rated for 4000m, with additional options for 3000m, 6000m, and OEM (no housing) versions available.

SPRINT Subsea Inertial Navigation system
Survey-grade inertial navigation for ROVs & AUVs
Designed for ROVs and AUVs, the SPRINT is an acoustically-aided subsea Inertial Navigation System (INS) that effectively processes data from USBL, LBL positioning, Doppler Velocity Log, and pressure sensors to enhance position accuracy, precision, reliability, and integrity.By integrating an AHRS (Attitude Heading Reference System) with an AAINS (Acoustically Aided Inertial Navigation System), subsea inertial navigation can commence or resume instantly upon receiving a position update, eliminating the need for a lengthy alignment period.
The SPRINT hardware platform maintains a continuous 15-day backup of all real-time navigation and raw data on an onboard SD card.

SPRINT-Nav Subsea Navigation Sensors
Integrated INS and DVL for precise ROV navigation
SPRINT-Nav is a comprehensive system that merges the SPRINT INS sensor with the Syrinx 600 kHz Doppler Velocity log and a high-accuracy bright pressure sensor, delivering high-performance subsea navigation for underwater unmanned vehicles. It is available in three performance levels and two depth ratings of 4000 and 6000 meters.
SPRINT-Nav Mini is a compact hybrid acoustic-inertial navigation system, perfect for observation-class and work-class rovs, as well as unmanned underwater vehicles operating in GPS-denied environments.
Utilizing the same proven algorithms as the larger SPRINT-Nav models, the SPRINT-Nav Mini effectively fuses its sensor outputs to deliver high-precision orientation, velocity, altitude, and depth data. This single compact unit replaces the need for separate AHRS, DVL, and pressure sensors, resulting in reduced cabling, fewer connectors, and simplified operation.
The SPRINT-Nav Mini is available in both 300-meter and 4000-meter depth-rated versions.
