Abstract :
One of the possible versions of wave gravity inertial orientation principle of animals and birds for realization in space is gravity inertial compass with floated sensitive element. The results of the analytical researches of solid body behavior are given. The body makes returned-forward oscillations along the vertical and is liable to transfer angular motion Earth diurnal rotation. In this case alternating Coriolis forces compel a solid body to make oscillations along line of prime vertical, i.e. in line Orient-West. On the basis of the received analytical results the construction of floated sensitive element is elaborated. Periodic changes of pressure allow stable float oscillations along the line East-West. Optical system makes a survey of information about these oscillations and identifies them with prime vertical direction. Recording of information is produced by video cameras. Experimental researches have shown determinations of reference direction stability and small time (several seconds) preparation and removal information. Received results of researches are used for making gravity inertial compass
