Description

Teledyne RD Instruments’ new Pathfinder DVL is precisely what our customers have been waiting for! This new highly compact 600 kHz DVL is small in size and huge on value. Derived from Teledyne RD Instruments’ long-standing, highly reliable DVL technology, this system promises to deliver the precision navigation performance you’ve come to expect from Teledyne RDI, at a price point, size, and weight that’s ideally suited for your next application.
Utilizing Teledyne RDI’s proven state-of-the-art electronics, the Pathfinder DVL provides an array of advanced internal algorithms and features you’d typically expect to find only in higher-end solutions. With up to 150 m of bottom tracking, in up to 300 m of water, the Pathfinder 600 delivers a solid, value-priced solution for
vehicles ranging from small inspection class ROVs to large diameter AUVs.
Utilizing Teledyne RDI’s proven bottom-detection algorithms and single-ping bottom-location accuracy
with its broadband velocity processing technology, the Pathfinder provides users with highly reliable precision velocity data for navigation and position control, even over indeterminate terrain.
The Pathfinder DVL is available off-the-shelf in a self-contained or OEM configuration, providing you with a footprint and flexibility that’s right for your unique vehicle requirements.

Product Features:

Small but mighty: Dramatically reduced size and weight allows Pathfinder to be installed on board the smallest vehicles with minimal impact on system payload.
Budget minded: Priced for smaller budgets, without the need to compromise on performance.
Proven Performance / Reliability: Building upon Teledyne RDI’s vast experience with DVL technology and performance, Pathfinder offers a proven, reliable solution to ensure the success of your mission.
New optional XRT (Extended Range Tracking) delivers 50% increase in bottom tracking range
Phased Array: Unique phased array transducer design delivers enhanced position accuracy at a reduced size, eliminates the need for speed of sound correction, and reduces drag on your vehicle.
Flexible Design: Self-contained or OEM package options available to meet your unique vehicle needs.
Versatile: Upgradeable to include Acoustic Doppler Current Profiling (ADCP) capability.
Ethernet Compatibility: Plug-n-play with today’s interfaces.

Other sensors

Dual Leak Sensor These instruments include leak detection sensors: one mounted near the connector end and one mounted at the transducer end of the DVL. This feature provides the user with real-time leak detection monitoring, allowing for peace of mind and strategic decision making during critical, high-pressure missions. Transducer Health Monitor The innovative transducer health monitor provides insight, in near real-time, about the status of the transducer, and alertsthe user of potential problems. The health monitor sensor also tracks pressure cycles, maximum pressure, and operating time for quality tracking purposes.
