VN-200 Start Up Sequence
Time: 0 sec
The VN-200 is operating as an AHRS.
Using the on-board magnetometer for
coarse heading estimation
Time: +30 sec
GPS Fix acquired. Local magnetic
declination applied. VN-200 still
operating as AHRS.
The VN-200 needs to exceed 5 m/s for
more than 1 second to start dynamic
alignment
During dynamic alignment accel and
GPS data are correlated to produce
yaw estimate. Typically take 60
seconds of sufficient motion to
complete alignment.
VN-200 Heading uncertainty is now
below 2 degrees. Sensor operating
within specification.
