FIELD: physics, navigation.
SUBSTANCE: invention is related to the field of instrument-making and may be used for definition of navigation parameters of motion of winged unmanned air crafts (UAC) that flies in ricochet mode. Method for homing of unmanned air craft in ricochet mode includes measurement of components of seeming acceleration and determination of gravity acceleration by means of measurement of signals in those moments of time, when derivative on seeming acceleration accepts value equal to zero, according to formula: 
where wyi, wy(i+1) - values of seeming speed of UAC; tj(i=1, 2, 3...), tj+1 - moments of time, when function wy is turned to zero.
EFFECT: higher accuracy of homing.
