SonTek RS5 User Manual (August 2020) 124
and the D(BT)/D(GPS) (Ratio of Bottom Track track distance to GPS track
distance) is approximately 1.
9. If using GPS, make sure the number of GPS satellites is good and the GPS
quality is valid.
10. On the Transect tab, evaluate different plots by right-clicking on the vertical axes.
11. Plot the depth measured by the Vertical Beam as well as Bottom Track depth.
Make sure the VB and BT depth scales are the same. Check for any major
discrepancies.
12. Evaluate Boat Speed and Water speed plotted on the same graph. Ideally, the
Boat speed should not exceed the water speed where possible.
13. Make sure that Heading/Pitch/Roll and Temperature are relatively constant.
14. Verify that the SNR data and beams are valid with special focus on the edges
and shallow water.
15. Verify water velocity in ENU: U (up) and D (Error Velocity) should be close to
zero.
16. Make sure that discharge curve and profile extrapolation is applicable (using
Processing Toolbox – Profile Extrapolation).
17. Verify that the SNRs are valid for the contour (graph at the bottom).
18. Verify that the velocity cell cutoff on the contour plot is valid, also look at the
screening distance and make sure that is graphically correct.
19. In the Discharge Measurement Summary make sure that:
References and Coordinates should be the same
Starting edges should alternate
Date/times should be consecutive
Duration of measurements should be similar
Use the Statistics to identify any outliers
Channel width and discharge areas should be similar
Uncheck or delete problematic records
