DVL Output Data Format (PD3) Details

The H-ADCP sends this data format only when the PD3 command is used. In multiple byte parameters,
the least significant byte always comes before the more significant bytes.

Stores the DVL (speed log) identification word (7Eh)

† Bit #0: Always output. If the data bit is set to 0, then Ship coordinates are used. If the
data bit is set to 1, then Earth coordinates are used. These fields contain the velocity of the
vessel in relation to the bottom in mm/s. Positive values indicate vessel motion to (X)
Starboard/East, (Y) Forward/North, (Z) Upward.
† Bit #1: Vertical velocities.
† Bit #2: These fields contain the velocity of the vessel in relation to the water reference
layer in mm/s. Positive values indicate vessel motion to (X) Starboard/East, (Y) For-
ward/North, (Z) Upward.
† Bit #1 and Bit #2
† Bit #3: These fields contain the vertical range from the H-ADCP to the bottom as deter-
mined by each beam. This vertical range does not compensate for the effects of pitch and
roll. When a bottom detection is bad, the field is set to zero.
Scaling: LSD = 1 centimeter; Range = 0 to 65535 cm
† Bit #4: These fields contain the average vertical range from the H-ADCP to the bottom as
determined by each beam.
