Abstract
A drill string rotation angle sensor diagnostic system includes a first rotation angle sensor assembly, a second rotation angle sensor assembly, an operator interface; and a control module. The control module is configured to receive a first signal from the first rotation angle sensor assembly, receive a second signal from the second rotation angle sensor assembly, determine if a valid state exists based on the first signal and the second signal, and indicate a fault on the operator interface if a valid state does not exist.
