Abstract
Aspects of the disclosure may reduce motion noise by mounting vector component sensors on a bottom-weighted instrument platform that is supported with a spherical bearing. An apparatus for data acquisition is provided. The apparatus includes a base assembly, a spherical bearing mounted to the base assembly, and an instrument platform having at least one vector component sensor fixed thereto. The instrument platform is mounted on and supported by the spherical bearing. The spherical bearing couples the instrument platform to the base assembly and allows free angular rotation of the instrument platform, within a tilt angle range. The instrument platform is bottom weighted in that it has a center of mass disposed below its center of rotation. The apparatus may include a controller that receives and/or stores data from the at least one sensor.
