2-Day Teledyne RDI Doppler Velocity Log (DVL) Training Course

Hosted in Houston, TX,  this course offers an in-depth overview of the principals and applications of Teledyne RDI’s DVL products as they apply to your underwater platform. 

Day 1 - Basic Training - Thursday, April 18, 2013
8:30 am - 9:00 am - arrival / continental breakfast
9:00 am - 5:00 pm - training (lunch and breaks provided)

This basic training will focus on the fundamentals of the DVL’s basic operation, diagnostics, and primary integration concerns.  Topics discussed will include:

• Basics of Doppler Shift
• Basic operational setup/software
• Data output and interpretation
• Ping rate and effect on accuracy
• Effects and importance of Speed of Sound, temperature, salinity, turbidity, roll, pitch, yaw
• Using a DVL at low altitude
• Using a DVL at low and high velocities - limitations and effects on accuracy 
• Differences related to beam orientation (Beam 3 forward vs. all beams at 45 degrees)
• Causes of saturation and ringing
• External sensors (Sound Velocity Probe, Temperature, and pressure sensors)
• Sources of interference.
• Using a DVL in conjunction with other acoustic sensors and the need for triggering
• Problem solving - Diagnostic Fundamentals for DVL’s
• Basic maintenance
• A look inside the DVL

Day 2 - Advanced Training - Friday, April 19, 2013
8:30 am - 9:00 am - arrival / continental breakfast
9:00 am - 5:00 pm - training (lunch and breaks provided)

This advanced training will focus on a combination of practical application and more advanced theory, with a focus on using the DVL for navigation as well as current profiling purposes, and interpreting the data output. Topics discussed will include:

• Determining average velocity and range from four independent beams
• Front end hardware (aliasing) and software (windowing) filters and their effects on response data
• Understanding broadband: 

          -Benefit vs. narrowband;

-Creating the transmit pulses

-Time domain correlation of receive data to transmit data; 

-Effects of uncorrelated external interference

-Understanding frequency domain response data

•  Using a DVL at low altitude
• Using a DVL for Current Profiling
• Differences related to beam orientation (Beam 3 forward vs. all beams at 45 degrees)
• Interpreting data in PD5, PD6, and PD0 data files, and when to use each file type.
• Understanding Ambiguity
• Using a DVL at low and high velocities:
  
  -Limitations
  -Effects on accuracy

• Variation with beam orientation
