sextant electronique has three axes of the inertial system and method of determination of the position

摘要

sextant electronic circuit comprising an inertial system 3 axes delivering a signal representative of the angle formed by the optical axis of a camera with respect to the vertical in the local terrestrial reference frame, a camera associated with a computer controlled by software for recognition of stars heavenly, and a clock. The recognition software determines the coordinates of the stars in the inertial frame of the universal j2000 and in that the sextant comprises a memory which stores the data for the determination of a transformation matrix making it possible to recalculate the coordinates stars in the frame of reference earth.
