FIELD: space engineering; methods of survey of earth surfaces from space.
SUBSTANCE: proposed method is based on use of optical electronic camera mounted on spacecraft. Spacecraft is injected into orbit at draconic period 
satisfying the following dependence:
where N is integer of turns, days; 
is integer which is lesser and simple at 
; 
is angular velocity of Earth; 
is angular velocity of longitude precession of ascending node of orbit; 
is so selected that fraction 
which is closest to 
, where 
is integer which is lesser and simple with 
and 
and N are selected in such way that altitude of orbit is located in required spherical layer.
EFFECT: improved characteristics of observation of earth surface by means of remote sounding apparatus.
