Determination of the Satellite Attitude Motion According to the Onboard Measurements Data

The methods for reconstruction of the rotational motion of the Earth scientific satellites from measurements of onboard sensors are presented in this article. The goal of this reconstruction is to gain the data for the analysis of the residual microaccelerations that were affecting during space experiments. It is sufficient to know the quasi-static (low frequency) component of microacceleration, to analyze the results of many experiments with gravitationally sensitive systems and processes. The quasistatic component of the microacceleration has frequencies less than 0.01 Hz and is determined from information of the satellite motion by calculation.
