About Precision survey
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.

Overview Revolutionising your subsea navigation SPRINT is the acoustically aided subsea inertial navigation system (INS) for all your ROV, towed platforms and AUV operations. Giving you flexibility, cost-effectiveness and ease of use, it embodies our commitment to bringing you innovation in subsea navigation. Get the SPRINT advantage SPRINT gives you:Robust performance in challenging subsea conditionsHigh-precision outputs for enhanced vehicle controlInstantaneous start-up without lengthy alignment periodsSeamless integration with your existing equipmentSPRINT 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
