description: The object of study is reception noise immunity and packet error rate of Satellite â Automatic Identification Systems signals. The aim is to increase signal reception reliability of the Satellite â Automatic Identification Systems by means of decollision processing. The work is devoted to the study of decollision signal processing algorithms in the space segment of automatic identification system (SAT-AIS). A universal simulation model has been developed. It takes into account the spacecraft orbital parameters, the characteristics of ground and space antennas, the ground transmitting stations distribution and their transmission power. The applicability of various GMSK-demodulators under space signal distribution and receiving has been investigated. As a method of signal collision mitigation an iterative collision avoidance algorithm is proposed, which increases the reliability of the SAT-AIS signal reception by 60%. Optimal configurations of processing algorithms and receiving antennas are determined for different application scenarios. Terminological features of the subject area are taken into account and software tools for problem solving are applied. Specialized software and mathematical software MATLAB is applied. The efficiency and applicability of the algorithm in real systems have been evaluated.
