METHOD AND DEVICE FOR DETERMINING ORIENTATION OF SPACE OR AIR CRAFTS Russian patent published in 2017 - IPC B64G1/36 G01C17/34 G01C17/38 

FIELD: aviation.

SUBSTANCE: group of inventions relates to orientation control of the space (SC) and air crafts (AC) by means of sensing elements. The device comprises orientation sensors (S) relative to the inertial coordinate system and relative to the astronomical objects positioned on the base. Wherein the device is provided with one-dimensional or two-dimensional (or their combinations) S of angular measurement for each of the mentioned S. S of angular measurement comprises a radiation source and a radiation receiver mounted on the base, and a reflective element - at one of the S of determining orientation. These elements are mounted so that the planes of the incident and reflected radiation beams are not parallel. The angles are measured, for example, between the running axes of orientation S and the base. Management of these angles (in the data processing unit) is intended to eliminate the influence of errors in orientation S position in body-fixed coordinate axes (e.g., due to deformation of the structure) on the measured parameters of the craft orientation.

EFFECT: increased orientational accuracy of the spacecraft or aircraft without increasing the rigidity of their structure.
