Making sure your navigation system operates properly before deploying a vehicle

How do you know if your navigation system is functioning properly before deploying your subsea vehicle? Nortek DVLs have several features and capabilities which can assure you that transducers are pinging and giving you reasonable values.

In this video, a Nortek field and test engineer runs through a typical test of a DVL, explains the issue of noise reducing range (and how Nortek's DVLs avoid it), and talks about how a spectrum analyzer can help identify interference and avoid issues.
