Abstract
A drilling assembly is equipped with apparatus that includes a device that periodically changes the resistance to the flow of drilling fluid through the drill pipe to create pressure pulses that can be detected at the earth surface and a sensor for controlling the pulse orienting device in response to the orientation of the drilling assembly relative to a preselected orientation relative to earth.
