METHOD DETERMINING TEMPERATURE CORRECTIONS IN PROCESS OF GRAVIMETRIC MEASUREMENTS

摘要

FIELD: measurement technology, measurement of gravity acceleration by nonthermostatting static gravimeters. SUBSTANCE: reference test with establishment of response of gravimeter to specified changes of temperature conditions is conducted. Forecasting recurrent dynamic model of temperature sluggishness is selected and employed to calculate temperature corrections to measurement results of temperature of device taken before and during flight with use of inertia coefficients found in process of reference tests. Calculated temperature corrections are applied to measurement results. Form of thermodynamic functional inertial dependence of internal temperature of system on temperature of environment for case of linear change of temperature is utilized as function of state for structural recurrent dynamic model. EFFECT: reduced temperature errors of gravimetric measurements under any temperature conditions. 3 dwg
