Abstract
In order to properly work, every distributed system need to know several parameters about local metrological devices. Some of these parameters may change because of environmental factors such as vibrations, thermal change or other accidental reasons. For this reason, a careful calibration activity is needed to achieve the best accuracy. During this phase, which can be automated to some extent, the system calculates information like network device positions and bearings, local temperature, humidity, pressure and so on. All this information is used during the measurement phase. Errors during the calibration phase adversely affect the accuracy of the measurements.
