Vehicle starts
Adjustment: select a predefined value from the drop-down list.
If you know the vehicle will be level when starting (to within about 5°) select Level.
This saves about 40 s during the initialisation process since the RT does not have to
take the time to compute an initial roll and an initial pitch. In high vibration
environments Not Level may not work and so the RT can only start if the vehicle is
level and the Level option has been specified.
Vibration
Adjustment: select a predefined value from the drop-down list.
The Normal vibration level is adequate for most circumstances. The RT is very
tolerant of vibration and has been used successfully in environments with more than 2 g
RMS using the Normal setting. If the velocity innovations are very high, and many
GNSS packets are being dropped, then this setting can be changed.
