Abstract
A cylindrical compass gimballing and data readout system permitting 360.degree. rotation about both yaw and roll axes includes a cylindrical compass housing flooded with semiconductive fluid to permit transmission of a digitally multiplexed signal from a remote reading compass to a processing unit in which the fluid is interposed between spaced-apart plates located along and perpendicular to the roll axis of the compass. This permits electrical connection to and from the compass, and permits not only 360.degree. rotation about the yaw axis for compass heading readout, but also 360.degree. rotation of the compass about the roll axis to permit use in seismic streamers.
