摘要： This publication relates to a system and a method for identifying or monitoring the orientation and position of a device, such as a tool, intended to be moved through or be stationary arranged a medium, such as rock, the system comprises an orientation unit (10) including an outer element (11) and an inner element (12). The system comprises further: -a fixed reference point member (13) is arranged on one element of the orientation unit; -at least one detector (15) for at any time sensing and thus identifying the position of the fixed reference point member(13); -at least one second detector (16) for sensing earth gravity; -device(s) for connecting the at least one first detector (15) and the at least one second detector (16) with a processor or retrieving collected data from said at least one first detector (15) and said at least one second detector (16), using such data from said at least one first detector (15) and said at least one second detector (16) for calculating and determining the rotational orientation of the fixed reference point member (13) relative to earth gravity.

摘要： The present invention relates to a system for identifying or monitoring the orientation and position of a rotary steerable drill for drilling in bedrock, wherein the system comprising; • a substantially non-rotating outer body element (1) housing at least one reference point magnet (14),, and • a rotating drive shaft (3), arranged inside the outer body element (1), that is connected to a drill bit (4) at its first end and to the drill rod (5), and • an inner body element (11) that is arranged inside the drive shaft (3), drill rod (5) or coupling thereof and where the inner body element (11) can be seated and retrieved from surface by means of a wireline. The inner body includes: - a cradle or platform (23) is arranged essentially concentrically inside the inner body element (11) being suspended rotationally free to the inner body element (11) enabling the cradle or platform (23) to freely rotate relative to the inner body element (11). The cradle or platform also includes at least one gravity sensor for at any time measuring the direction of earth's gravity relative to the said cradle or platform (23), and at least one alignment device (19) configured to align said cradle or platform (23) in a known rotational position relative to a reference constituted by the reference point element (14) or the direction of earth's gravity.
