Parameter Name
Description
Size
VB_Depth
Vertical Beam depth for each sample, including the Transducer
Depth and compensation for tilt
NS x 1
BT_Depth
Mean Bottom Track depth for each sample, including the Trans-
ducer Depth and compensation for tilt. This is the mean of the
depth measured by each active transducer and projected in verti-
cally below of the ADP
NS x 1
BT_Vel
Bottom Track Velocity for each direction (or beam, if exported in
Beam coordinates) for each sample
NS x 4
BT_Beam_Depth
Bottom Track depth for each beam for each sample, including the
Transducer Depth and compensation for tilt
NS x 4
BT_Frequency
Frequency used for Bottom Track data for each sample (correlate
with Frequency parameter from Transformation_Matrices struc-
ture)
NS x 1
Units
Units for above parameters (BT_Frequency is kHz)
NA

GPS_Age
Time since the last corrected GPS signal received at the rover
GPS antenna, whether from the RTK Base Station or from the sat-
ellite if using the SonTek DGPS option
NS x 1
Altitude
Altitude above mean sea level for each sample
NS x 1
GPS_Quality
GPS Quality for each sample
(5 = RTK float, 4 = RTK fixed, 2 = Differential, 1 = Standard, 0 =
Invalid)
NS x 1
GpsGeoid
Gps Geoid Height is the distance between the geoid (mean sea
level) and the WGS84 ellipsoid
NS x 1
UTM
Universal Transverse Mercator (UTM) coordinate system in X and
Y coordinates for each sample
NS x 2
Units
Units for above parameters (GPS_Age are in seconds)
