A method of adjustment of trajectory of a free-falling container for its delivery into a given point, which includes assignment of coordinates of the point of delivery of the container, a drop of the container from the aircraft, determination of current coordinates of the container by means of a system of satellite navigation, moreover the assignment of coordinates of the point of delivery of container, in particular of geographic latitude &phgr;, geographic longitude of λand height Hof location of the container above the terrestrial geoid is made by means of an unit of introduction of coordinates of the point of delivery of container with their subsequent, after drop of the container from aircraft, transmission to an onboard digital computer. Into onboard digital computer from the system of satellite navigation the current coordinates of the falling container are also transmitted, in particular the current coordinates of geographic latitude &phgr;, longitude λ and height H of location of the container above terrestrial geoid, and also from the sensor of angular signal velocity about change of the angular rate of rotation of container ω. At reaching the value of current height H of the location of container above terrestrial geoid, which is equal to assigned H, a signal for parachute opening is delivered. |
