Methodic error

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.
