摘要

As is well known, in Low Earth Orbit, besides gravitational force, a number of perturbing factors influence a spacecraft's trajectory. It is possible to divide these perturbations into two basic groups: gravitational - due to Earth's non-sphericity, other celestial bodies attraction (The Sun, the Moon) and non-gravitational — due to mainly atmosphere drag and direct/indirect solar radiation pressure. A very sensitive, electrostatic, feed back, three axial and symmetrical microaccelerometer MAC with the cubic proof mass was developed for the measurement of the accelerations rising by virtue of non-gravitational perturbing on the spacecraft board. Some examples of non-gravitational perturbations and corresponding accelerations are shown in table 1 (for Low Earth Orbit and characteristic value dependency of effective area and spacecraft mass is equal to 0,005 m2/kg). Hereafter, the article describes a principle of microaccelerometer measurement on spacecraft board, block diagram of instrument control circuits and its analysis.
