METHOD FOR DETERINATION OF COORDINATES OF FLIGHT VEHICLE Russian patent published in 2005 - IPC

FIELD: procedure of indirect measurements of coordinates of flight vehicle that may be used, in particular, in complex in flight control systems of flight vehicle.

SUBSTANCE: the method is based on coordination of measurements of flight vehicle, ranges to a group of ground radio beacons being in the zone of its direct visibility with the aid of a position navigation sensor with evaluations of the ranges obtained with the aid of reproduction of the flight vehicle trajectory by solution of differential equations of its motion, substituted in which are the measurements of the airborne sensors and the course vertical. The method provides for determination of the coordinate of the flight vehicle at an arbitrary flight trajectory with a high precision required, for example, at a landing approach an at a landing, it also provides for continuity of determination of coordinates at a failure of measurements of the position navigation sensor, for example, at a maneuvering of the light vehicle.

EFFECT: enhanced reliability.
