Teledyne RD Instruments

Teledyne RD Instruments is a U.S. marine-instrumentation manufacturer within Teledyne Marine, known for acoustic Doppler current profilers, Doppler velocity logs, wave-measurement instruments, water-resources flow systems, and underwater-navigation sensors. The company traces its origins to the 1982 development of the first commercial ADCP and operates from a San Diego-area facility in Poway, California.

Teledyne RD Instruments supplies acoustic Doppler instruments used to measure water currents, support oceanographic survey work, and provide velocity data for subsea vehicles. Its public product lines cover marine measurements, precision navigation, and water-resources applications, linking the manufacturer to cataloged support equipment rather than direct weapon effects.

The manufacturer's catalog relevance comes from sensors and navigation instruments that can appear in naval, survey, unmanned-vehicle, or hydrographic equipment suites. Teledyne's parent reporting places marine instrumentation inside its Instrumentation segment, while Teledyne Marine identifies RDI as a San Diego-based operation with engineering, laboratory, manufacturing, and test areas.

Acoustic Doppler Current Profiler (ADCP), Current profiling instrument, Support EquipmentAcoustic Doppler Current Profiler (ADCP)Current profiling instrumentBuilt in: United States / NorwayAcoustic Doppler Current Profiler (ADCP) is a hydroacoustic current-measurement instrument that uses Doppler-shifted sound returns to profile water-current speed and direction through the water column. Teledyne RD Instruments, Nortek, NOAA, NASA, and USGS sources document ADCPs as shipboard, moored, seafloor, buoy, vehicle-mounted, and river-discharge instruments, with the cataloged Haixun 08 fit showing how this commercial sensor class appears in a hydrographic survey-vessel suite.
