According to one aspect of the invention, a method for calibrating a torque measurement for a rotatable object is disclosed, wherein the method includes coupling the rotatable object to a structure, the structure including a member extending along a length of a surface of the rotatable object, coupling the rotatable object to an adapter and applying a known torque to the rotatable object via the adapter. The method also includes measuring a first rotational displacement via a first sensor coupled to the member at a first axial location of the rotatable object, measuring a second rotational displacement via a second sensor coupled to the member at a second axial location of the rotatable object and determining first and second angular displacements of the rotatable object based on the first and second rotational displacements.

Method and apparatus for calibrating a torque measurement

Certain embodiments of the invention may include systems and methods for providing a translating telemetry stationary antenna. According to an example embodiment of the invention, a method is provided for automatically aligning a stationary antenna with a corresponding rotor antenna. The method provides for mounting a stationary antenna with respect to a rotor antenna associated with a rotor. The method includes mounting a stationary antenna to an inner circumference of a support frame, mounting a plurality of radial air bearings to the support frame for maintaining radial alignment of the stationary antenna with respect to the rotor antenna, and mounting a plurality of axial air bearings to the support frame for maintaining axial alignment of the stationary antenna with respect to the rotor antenna.
