NAV-VIEW provides an easy to use
graphical interface to display, record,
playback, and analyze all of the
AHRS380ZA Attitude & Heading
Reference System parameters.
NAV-VIEW can also be used to set a
wide range of user-configurable fields
in the AHRS380ZA to optimize the
system performance for highly
dynamic applications.
NAV-VIEW software is available for
download from MEMSIC’s website at:
www.memsic.com/support
Other Components
The AHRS380ZA can be evaluated
using the EVAL-KIT DMU380ZA-200 or
-400 kit (depending on range
purchased), allowing direct connection
to a PC for use with NAV-VIEW display
and configuration software.
