  • Patent number: 5155327
    Abstract: A laser pointing system directs a laser beam at one face of a steering mirror to produce a steered reflected beam. A highly attenuated portion of the laser beam passes through the mirror leaving at a second side, which side also reflects a stellar field. A star of the stellar field and the attenuated beam are both imaged on a star tracker. The mirror is moved so the two images coincide, thus aligning the steered beam parallel to the direction of the star. A gyro package detects changes in the system orientation to update the mirror reference position, and a processor provides command coordinates to move the beam from the stellar coordinates and cause it to point in a selected target direction.
