High-speed noise-proof communication lines are an important element that ensures the successful solution of the problems of the functioning of space-based Earth sensing systems, therefore laser communication systems are an important component of promising means. At the moment, there are factors limiting the use of lasers for communication in space – scattering and the complexity of beam guidance. In satellite optical communication, the minimum bit error coefficient is important while ensuring the minimum radiation power. In the work, a mathematical model of the communication and tracking system is obtained, which provides the optimal value as a function of the gain of the transmitter. The purpose of the work is to show a mathematical model that determines the optimal aperture of the transmitter as a function of the signal ratio/ noise of the satellite tracking system with a minimum bit error rate.
