Vibration - Advanced Navigation Spatial Dual Reference Manual

Vibration

Spatial Dual is able to tolerate a high level of vibration compared to other inertial
systems. This is due to a unique gyroscope design and a special filtering algorithm.
There is however a limit to the amount of vibration that Spatial Dual can tolerate and
large levels of vibration can cause Spatial Dual's accuracy to degrade.
When mounting Spatial Dual to a platform with vibration there are several options. It is
recommended to first try mounting Spatial Dual and see whether it can tolerate the
vibrations. The raw sensor view in the Spatial Dual Manager software can give you a
good idea of how bad the vibrations are, see section 11.7.4. If the vibrations are
causing the sensors to go over range you will need to increase the sensors range, see
section 10.5.
If Spatial Dual is unable to tolerate the vibrations there are several options:
1. Try to find a mounting point with less vibration.
2. Spatial Dual can be mounted with a small flat piece of rubber.
3. Spatial Dual can be mounted to a plate which is then mounted to the platform
through vibration isolation mounts.
