Example Waves Setups
The
Waves + Currents
template samples Profile 1 at 2 Hz so that the noise floor can be
characterized with Profile 2 at 1hz.
The
Continuous Waves
template samples at 2 Hz.
If the deployment duration requires >30 days with a V100 system:
•
Add an external battery case or Lithium battery
Or
•
Reduce the number of wave pings/burst from 2100 to 1024 while keeping
the ping rate at 2 Hz (0.5 seconds/ping).
Reducing the burst duration should not be performed on any western ocean boundaries
where you have low frequency ground swell (i.e. Alaska to Chile on the pacific, or UK to Africa
in the Atlantic). If you are on the eastern boundary of the ocean, a 1024 ping burst is
acceptable.
To profile to a range less than 49.6 meters:
•
Change the bin size to <1.2 meters.
To profile to a range of >99 meters, you must:
•
Clear the ping collision error by setting the ping rate of the waves burst (Profile 2 only!) to 1.25
seconds
•
With 1.25 seconds, the power consumption is much larger, suggestions are to:
o
Add an external battery case or Lithium battery
o
Further reduce the number of pings per wave burst to <1024 to allow 30 days
Version 1.5 of
Velocity
will “zero fill” the burst to deal with non-powers of 2 FFT lengths.
If you make changes to any of the Profile settings, the name of the profile will change to
Custom.
Opening a Saved Scenario
To open a saved Scenario:
1. Click anywhere on the
Step 1 Set sampling strategy
section on the Home panel.
2. To open a scenario, click the
Import
button. On the Open dialog, select the deploy-
ment scenario file (*.txt). Click the
Open
button.
3. Use the
Step 1 Set sampling strategy
panels to adjust the scenario settings if needed.
4. If changes are made, click the
Export
button to save the selected scenario (*.txt) to
the computer. On the Save As dialog, name the deployment scenario file (*.txt).
Click the
Save
button.
