Claim 0:
1. A system for transmitting information, the system comprising:
a first communications unit and a second communications unit, each communications unit comprising a transmitter, a communications photodiode (CPD), one or more steering mirrors, a position sensitive detector (PSD), and one or more actuators,
wherein the transmitter of the first communications unit comprises a laser for sending a laser beam to the second communications unit,
wherein the transmitter of the second communications unit comprises a laser for sending a laser beam to the first communications unit,
wherein the PSD of the first communications unit:
obtains positioning and/or steering information from the laser beam incoming from the second communications unit, and
controls positioning and/or steering of the laser beam of the first communications unit in order to, despite motions of the laser beams, (i) keep the laser beam of the first communications unit directed at the second communications unit and (ii) keep the laser beam from the second communications unit aligned on the CPD of the first communications unit, and

wherein the PSD of the second communications unit:
obtains positioning and/or steering information from the laser beam incoming from the first communications unit, and
controls positioning and/or steering of the laser beam of the second communications unit in order to, despite the motions of the laser beams, (i) keep the laser beam of the second communications unit directed at the first communications unit and (ii) keep the laser beam from the first communications unit aligned on the CPD of the second communications unit,

wherein:
(i) a first steering mirror of the one or more steering mirrors of the first communications unit receives the laser beam incoming from the second communications unit, and wherein a second, separate steering mirror of the one or more steering mirrors of the first communications unit contacts the laser beam of the first communications unit before the laser beam of the first communications unit passes to the second communications unit, and/or
(ii) a first steering mirror of the one or more steering mirrors of the second communications unit receives the laser beam incoming from the first communications unit, and wherein a second, separate steering mirror of the one or more steering mirrors of the second communications unit contacts the laser beam of the second communications unit before the laser beam of the second communications unit passes to the first communications unit.
