A bi-directional pointing and tracking system is needed in order to establish the optical link between two optical transceivers located in two separated points at the ground or on satellites. That usually suppose the presence of a separate laser transmitter an optical beacon used for pointing and tracking purposes. The major stages of the pointing and tracking process were analyzed based on a mathematical model presented in references. In order to increase the reliability of optical links a new optical beacon is purposed and, consequently a new pointing and tracking method is developed. This method requires only communication laser transmitters and uses their optical beams for pointing and tracking process, additionally giving the possibility to increase the signal to noise ratio at the communication receiver. A mathematical model of such a system is developed and an analysis of the method is performed.
