METHOD OF DETERMINING RELATIVE POSITION OF OBJECTS Russian patent published in 2012 - IPC G01S11/12 

FIELD: physics.

SUBSTANCE: method involves forming a measuring system consisting of a set of optical reference marks made on the first object, said set comprising not less than three reference optical emitters, and an optical measuring set installed on the other object. Radiation power of each reference optical emitter is modulated on a repetition frequency different from other frequencies, while periodically generating time marks simultaneously at all frequencies. The optical measuring set is used to determine viewing angles of each reference optical emitter and the difference between the distance to a randomly selected reference optical emitter and distances to the rest of the reference optical emitters and parameters of relative position of the objects are calculated based on these data.

EFFECT: unambiguous determination of parameters of relative position and relative orientation of two objects, minimising the number of reference optical emitters required to ensure unambiguity, possibility of taking measurements in conditions of direct solar illumination of the optical measuring receiver and high accuracy of measurements in case of re-reflection of signals of the reference optical emitters from the objects.
