RDI Doppler BottomTrack Speed (Remote Cherry) - 30


Driver to decode bottom track forward and starboard velocity from an ASCII output data ensemble from a RD Instruments (RDI) Acoustic Doppler Current Profiler (ADCP), using the Remote Cherry Display Output Format.
The driver returns the horizontal velocity along with its direction (heading).

Decoding Notes

The driver always wants to receive velocity relative to the bottom (see format A).

The defined Direction observation (Database Setup) should always be of Type "Angle" (not Bearing, True).

Interfacing Notes

No special two-way RS-232 cable connection is required.
The driver does not send any command to the Doppler, so the unit should already be in continuous data output mode.

Database Setup

The unit for the Speed observation should be meters/second, the recommended a priori sd 0.1.

The unit for the Angle observation should be degrees, the recommended a priori sd 5.0.

Drivers IO Notes

The Qinsy RDI driver has the possibility to validate the speed data that is being decoded.
To use this feature the user has to manually edit the "DRIVERS.IO" file. Locate the DrvRDIRemoteCherry.exe driver.
Any number that is present as command line argument will be used as the maximum speed to be accepted by the driver.
