Abstract
A drill control system includes an uphole control device and a downhole control device. The uphole control device is configured to transmit a reference trajectory to the downhole control device and receive information about an actual trajectory from the downhole control device. The downhole control device is configured to receive the reference trajectory from the uphole control device, measure the actual trajectory, correct deviations between the reference trajectory and the actual trajectory, and transmit information about the actual trajectory to the uphole control device.
