MAP-BOARD FOR SELECTION OF OBJECT FOR OBSERVATION FROM ORBITAL SPACECRAFT Russian patent published in 2008 - IPC G01C21/24 G09B29/00 

FIELD: transportation, astronautics.

SUBSTANCE: map-board for selection of object for observation from orbital spacecraft (SC) includes flexible tape with two copies of planet surface map applied on it with aligning the Equator end point of the first map copy with the Equator start point of the second map copy, device providing map tape movement from two spaced and secured in parallel shafts. At that, the tape is looped and located on shafts with possibility of its circular motion along equator line of the maps. Additionally following is introduced: translucent tape with the image of continuous line of route for at least three sequential aircraft orbit passes, device providing movement of the tape with image of orbit along the tape with maps from two spaced and secured in parallel shafts and device for synchronisation of movement of the tape with maps and the tape with orbit image. At that, the tape with orbit image is looped and located on shafts of device providing movement of the tape with orbit image with possibility of its circular movement along equator line of the maps. Length of the tape with orbit image is made equal to overall length of represented orbit passes as measured along the equator direction, length of the tape with maps is made equal to total length of equators of plotted on the tape maps, and width of the tape with orbit image and width of the tape with maps are made in the ratio equal to ratio of orbit inclination angle to 90°, at that diameter of shafts of devices providing movement of the tape with orbit image is made equal to diameter of shafts of device providing movement of the tape with maps and constitutes value not exceeding one-fourth of difference between length of the tape with orbit image and length of the tape with maps.

EFFECT: map-board functionality enhancement due to providing of representation on the map-board previous and consequent orbit passes of aircraft.
