An Analysis Of Low-frequency Component In Microacceleration Measurements Made Onboard The Foton M-2 Satellite

摘要

The low-frequency component is investigated in the data of measurements performed onboard the Foton M-2 satellite with the three-component accelerometer TAS-3. Investigations consisted in comparison of this component with its calculated analog found from a reconstruction of the satellite's attitude motion. The influence of the Earth's magnetic field on the accelerometer readings is discovered by way of spectral analysis of the functions representing the results of determining the low-frequency microacceleration by two methods. After making correction for this influence, the results obtained by these two methods coincided within a root-mean-square error of less than 10~(-6) m/s~2.
