Dpeloyement planning and measurement load

Hi we recently purchased an Aquadopp and a AWAC. We normally use 600s profile intervals and an averging interval that will offer a precisionof 2cm/s or better. I noticed that the measurement load varies as I change the averaging interval. Why does it do this? I also noticed that I could select to control this manually but wondered what advantage there was of a longer averaging interval and lower measurement load compared with shorter averaging interval and a higher measurement laod.

thanks

Hi there

Here are a couple of postings that may be of help:

System integration and telemetry

The advantage of using longer averaging interval and lower measurement load is that you get a better statistical averages.  If your average time is too short, the estimate of the mean currents could be dominated by short term effects like surface waves.
