Abstract (en)

[origin: WO2016024867A1] 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.
