<p>A multifunction orientation system comprising a primary measuring means for measuring a drilling characteristic, at least one secondary measuring means for taking a set of orientation related measurements and a user interface means for receiving data from, and communicating data to, a user. The user operates the user interface to enter in a set of threshold values for the drilling characteristic. When the primary measuring means determines that the current measurement of the drilling characteristic exceeds one of the set of threshold values, the at least one secondary measuring means operates to take measurements as required by the set of measurements and communicate those measurements to the user.</p> |
