METHOD OF ANGULAR ORIENTATION OF OBJECT BY SIGNALS FROM SATELLITE RADIO NAVIGATION SYSTEMS ( VARIANTS ) Russian patent published in 2002 - IPC

FIELD: satellite radio navigation. SUBSTANCE: method can be employed for spatial orientation of mobile objects by interferometric method with size of interferometer base up to several meters. Technical result of invention lies in finding of initial and present angular positions of mobile object without any forced change of orientation of vectors- bases on which ends antennas are placed. Technical result in agreement with first variant is achieved by determination of present angular orientation of object by way of solution of system of equations written by m measurements of phase shifts of signals of n spacecraft of satellite radio navigation system (n≥4, m≥4). In accordance with second variant technical result is achieved by determination of initial angular orientation of object and by its change with reference to initial angular orientation which are found by differences of isochronous measurement of phase shifts of signals of n spacecraft (n≥6),, by present values of directing cosines of vectors-base from object to each spacecraft and by their increments during measurement time. EFFECT: finding of initial and angular positions of mobile object. 2 cl, 1 dwg
