FIELD: instrument making.
SUBSTANCE: device comprises a globe with a planet surface map applied on it, a spiral element that models an orbit of a spacecraft (SC), a facility to lock the spiral element on the axis of globe rotation. The spiral element is arranged in the form of an orbit turn with a positive incline of the SC. The start of the orbit turn shall be a point of the orbit located beyond the quarter of the SC circulation period to the ascending unit of the orbit. The end of the orbit turn shall be a point of the orbit that is distant by the quarter of the SC circulation period after the next ascending unit of the orbit. The facility for fixation of the spiral element on the axis of globe rotation is arranged in the form of two connection elements, the angular size of every of which, measured from the centre of the globe, is equal to 90°-i, where i - orbit inclination.
EFFECT: expansion of functional capabilities.
