METHOD OF DETERMINATION OF COEFFICIENTS OF INSTRUMENTATION ERROR MODEL OF NAVIGATIONAL SYSTEM Russian patent published in 1995 - IPC

FIELD: precision instrumentation engineering. SUBSTANCE: sensitive element unit is smoothly moved from one fixed position to another and "n" magnitudes and angular velocity are measured between these positions both with the aid of sensitive element unit and without it; then magnitudes of acceleration and angular velocity measured from sensitive element unit are multiplied one by one and by one another to obtain squares and cubes of acceleration and their cross magnitudes in accordance with adopted error model; magnitudes of acceleration, angular velocity and their products are multiplied by coefficients of error model, then total error of model is formed, independednt total errors are calculated after which difference between these errors is determined which is used for calculation of new magnitudes of coefficients. EFFECT: reduction of time required for determination of coefficients. 1 dwg
