2. If you can identify a heading offset then enter this value in the
Heading Correction field of the GAMS Parameter Setup window,
see
Figure 31 on page 4-29. Select the OK button to install the new
correction value.
POS MV will then compute new components of the surveyed antenna
baseline vector having a corrected azimuth.
3. Select Settings, Save Settings from the MV-POSView menu bar to
save the new values to the PCS Non-Volatile Memory (NVM).
Note: The Heading Correction field in the GAMS Parameter Setup window
allows you to correct an inaccurately surveyed baseline vector. You can use
this method to obtain a more accurate vector.
Note: You should not use this facility to implement the installation angles of
the IMU body frame with respect to the echo-sonar frame. Refer to the
Installation Parameters and the Configuration Data descriptions on pages 2-
38 and
4-12 respectively, for instructions on how to measure and enter these
installation parameters.
