SPRINT is an acoustically aided Subsea Inertial Navigation system for subsea vehicles. SPRINT makes optimal use of acoustic aiding data from acoustic USBL and LBL positioning and other sensors such as Doppler Velocity Log (DVL) and pressure sensors. This improves position accuracy, precision, reliability and integrity while reducing operational time and vessel costs. The system extends the operating limits of Ultra- Short BaseLine (USBL) and can dramatically improve the operational efficiency of Long BaseLine (LBL). The new third generation SPRINT unit offers power pass-through to aiding sensors, reducing cabling and interfacing complexity.

SPRINT INS shares the same hardware platform as Lodestar AHRS and is a combined AHRS (Attitude Heading Reference System) and AAINS (Acoustically Aided Inertial Navigation System). Running both the AHRS and INS algorithms concurrently allows inertial navigation to start or restart instantaneously on receipt of a position update as the AHRS seamlessly provides orientation to the INS on start-up. This avoids the lengthy ‘alignment’ period common to other INS systems. Thereafter, the separate AHRS and INS computed orientation are autonomously monitored as an indication of system health.

All AHRS and AAINS computations are performed within the Lodestar, making the system robust and resilient to communications issues. Lodestar maintains a rolling 15 day backup of all real time navigation and raw data on an onboard SD card which can be retrieved if required. Coupled with concurrent logging of all data by the topside software, data integrity is ensured.

• Popular for navigating ROVs and AUVs
• Speeds up operations – saves you vessel time
• Small, lightweight and easy to install
• Track record spanning more that 10 years
• Range of performance levels to suit your task

SPRINT Nav is an all-in-one subsea navigation instrument for underwater vehicles. t combines Sonardyne’s SPRINT INS, Syrinx DVL 600 kHz (Doppler Velocity Log) and high accuracy intelligent pressure sensor in a single housing that is one of the smallest combined inertial navigation instruments on the market.

The unit is comprised of three high grade Ring Laser Gyros (RLG) and accelerometers. These ultra-reliable sensors are used also for safety critical navigation by the majority of the world’s large commercial aircraft and do not require factory recalibration over the product’s lifespan.

SPRINT-Nav’s dual algorithm capability is unique in the market and allows for simultaneous use from one instrument, e.g. AHRS plus DVL for ROV piloting, INS plus DVL for survey operations.

The SPRINT and Syrinx components can be operated as standalone sensors, independently of one another depending on the need. SPRINT-Nav is calibration free.

With power-pass-through, aiding sensors can be powered directly, reducing cabling cost and complexity. Sensor offsets are rigid and very accurately known, helping to reduce systematic errors in lever arm measurements. The pressure sensor module can be removed for calibration or repair without incurring downtime.

Each Syrinx transducer is fitted with a full depth rated water block to ensure protection of the internal components.
