A top drive assembly may comprise a drive motor that provides rotational torque to a drill string for driving the drill string into the earth. A sensor and a transmitter may be located on a section of the drill string or on a device that can be incorporated into a drill string. The sensor may take measurements of the drill string that is rotating during the drilling operation. If the sensor is located near the top drive assembly, the sensor may take measurements of an upper portion of the rotating drill string during the drilling operation. The transmitter may wirelessly transmit the sensor information in real-time to a coordinator or main radio. The transmitter may also be located near the top drive assembly and during the drilling operation, may transmit from the rotating drill string while located in a position above the earth's surface.
