multi-beam sonar. The system also estimates and displays the accuracy of its
attitude and heading measurements.
TrueHeave
TrueHeave (different than real-time heave) is based on an advanced two
sided filter, making use of both past and present vertical motion data to
compute a significantly improved heave estimate. POS MV has sufficient
computational speed such that a secondary estimate of heave can be
accomplished shortly after the sonar acquisition event.
Delayed time heave output not only removes many of the compromises that
must be made in real-time, but provides near real-time Quality Control (QC) of
heave performance. The MV-POSView graphical interface includes a time
series plot of both real-time and TrueHeave estimates, which allows the
operator to react if a divergence between the two heave estimates is
observed.
(As a software option on the MV 320, TrueHeave must be enabled before
use. Contact your Applanix Customer Support representative for the
appropriate authorization code; refer to page
A-1 for contact details.)
Refer to the
TrueHeave Operation description on page 6-1 for a full
description of the data formats used by POS MV to output these parameters.
Analog Interface
The analog interface hardware option delivers motion measurements (roll,
pitch and heave) for use by external equipment such as an echo-sonar.
