Experimental research of an on-board laser acceleration measurements for the gravitational field parameters estimation on cubesate nanosatelite

The paper considers the possibility of constructing a device for a acceleration measurement based on an optical interferometer instead of a capacitive measuring system. The design of polarization single-frequency interferometer is considered. The layout of the accelerometer sensing element and a bench for measuring its sensitivity are also described. The results of the study are presented and prove the possibility of achieving sensitivity not worse than $10^{-8} \mathrm{~m} / \mathrm{s}^{2}$.
