Configuration and Display Software
NAV-VIEW provides an easy to use
graphical interface to display, record,
playback, and analyze all of the
AHRS380SA Attitude & Heading
Reference System parameters.
NAV-VIEW can also be used to set a
wide range of user-configurable fields
in the AHRS380SA to optimize the
system performance for highly
dynamic applications.
NAV-VIEW software is available for
download from MEMSIC’s
