which provides the TrueHeave output, the equivalent of the real-time heave solution and the applicable
Time of Validity (TOV) signal. Group 113 contains the associated performance metrics.
Groups 111 and 113 data are output on the real-time Ethernet data port at a rate of 25 Hz to provide
sufficient resolution on the Heave Data display, see Figure 53. It may be selected for internal or Ethernet
logging.
Note: The heave data output, in real-time, is in no way affected by the addition of TrueHeave; it can and
should continue to be used as normal.

TrueHeave Procedure

Use the following procedure to enable the TrueHeave feature prior to its first use.
1. Initialize POS MV ensuring that all pre-set user accuracy values are acceptable. This is indicated
by green light buttons adjacent to the Attitude, Heading, Position, Velocity and Heading labels in
the Accuracy pane on the MV-POSView Controller, see Figure 54.
2. View real-time heave and TrueHeave data by selecting View, Heave Plot, see Figure 53. Due to
the delay inherent in creating the TrueHeave solution, the heave data plot remains blank for the
first three minutes after initialization.
