11.2 LBL accuracy
The position accuracy for LBL operation depends on the
transponder array geometry, sound velocity errors and signal to
noise ratio. Range accuracy’s down to a few centimetres can be
obtained, while ROV and vessel positions can be calculated to
within a few decimetres.
Table 1 and Figure 8 show acoustic parameters and position
accuracies that are achieved in deep waters when using an array
with four transponders at water depth 3000m.
