1. A method comprising:
monitoring a signal indicative of an orientation of a downhole tool, in which the downhole tool orientation is monitored using a rotational sensor at a spindle;
selecting a desired downhole tool orientation;
actuating rotation of a spindle configured to provide rotational force to the downhole tool;
causing rotation of the spindle to cease when the signal indicates the downhole tool is within an error tolerance of the desired downhole tool orientation;
actuating advancement of the downhole tool;
while advancing the tool, monitoring the signal; and
while advancing the tool, rotating the spindle to maintain the downhole tool within the error tolerance of the desired downhole tool orientation.
