The paper considers methods for receiving and processing automatic identification of ships (AIS) signals by a small satellite (CubeSat). A comparison of various methods for reducing the impact of collisions on the reliability of reception is given, such as the choice of orientation and type of the CubeSat receiving antenna, the use of various demodulation algorithms that take into account the presence of Doppler frequency shifts, as well as decollision processing algorithms. Using simulation modeling that takes into account the parameters of the space scenario (orbit altitude, antenna type, etc.), the efficiency of the considered methods in terms of reducing the packet error in the presence of first-order collisions is shown.

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
