Abstract

An inertial measurement unit (IMU) is provided that includes a container that defines a cavity. A sensor suit or ISA having a housing is provided in the container of the IMU. A dampening material is provided between the housing of the ISA and the container of the IMU. The dampening material may be applied by coating, spraying, or dipping, or may be separately molded and then inserted, if desired. A sway space may also be provided between the ISA and the IMU container.
