Special orientation during logging is a very important task, and it is essential in almost all borehole tools. For this purpose, various orientation sensors (such as accelerometers, magnetometers, and others) are usually used. During logging, the task is being complicated with increasing temperature range and device vibrations due to the movement along the borehole. Thus, this paper describes experimental results in the downhole logging of the developed digital spatial orientation module, which was integrated into...
