... the orbit of a space-craft N o 1 : period - about 9 days, perigee - 75 000 km, apogee - 300 000 km; the orbit is subjected to of systematic disturbances by Moon, and consequently ensures the obtaining of high quality images for any sky objects; . ...
... The orbit parameters are chosen such that the gravitational perturbation from the Moon and the Sun provided the largest rotation of the orbital plane around the axis of apsides, and a motion of the axis. ...
... of the orbit resulting from gravitational perturbations by the Moon, will give some degree of two-dimensional coverage ... and electronic components and in calibrating the pointing of the antenna using the Moon and other strong cosmic radio sources ...
