The analysis of implementation methodology of sound metric stations AZK-5 and AZK-7, which are adopted by the Armed Forces of Ukraine and some other countries, shows that this methodology provides an approximation of the second-order curve – hyperbola, which describes the location of the target by its asymptotic rays. This approximation provides simplification of algebraic and geodesic computing. Nevertheless, it causes the emergence of methodology error of target bearing process.
Consideration of the liquid-in-tube thermometers envisages that the performance depends on their linear sizes and the row of thermophysical properties. Methodic error is defined by the ratio of the complex parameters that take into account the mentioned characteristics of the measured object and the thermometer. We consider the liquid-in-micro tube thermometers for measuring temperature.
